QUICK SETUP: Note: For detailed instructions for each type of detector, refer to the Operating Procedures section. 1. Turn On the Meter: Note: For the most accurate measurements possible, the S310 should be turned on and warmed up for 30 minutes. Note: For information on Group Settings, refer to the Group Settings section. Press the ON switch located in the rear panel of the meter. The S310 will immediately turn on with its operational state based on the last used detector Group Setting.
5. Select a Range: On the first press of the RANGE button, the analog scale (if active) will disappear. Then briefly press the RANGE button each time another range is desired. Press the SELECT button when the range you desire appears in the display (failure to press the SELECT button within 3 seconds will activate the range shown in the display and return the S310 to its operation state). 6. Select a Mode: The MODE button allows selection of the type of measurement to be made (watts, joules, etc).
2. Group Settings for Astral or Large Aperture Calorimeters: Note: The factory default Group for Astral or Large Aperture Calorimeters is Group #1. Note: Pressing the CANCEL button at any time during this process will terminate this process with no changes made. Note: Holding down the SELECT button for 3 seconds at any time during this process will save any changes made up to that point and return the S310 to its operational state for the Group selected.
To set the time delay between pulses use the count up (RANGE) and count down buttons (MODE) buttons to enter the time in seconds. Press the SELECT button after the time has been entered to save the setting.
3. Group Settings for Vector Pyroelectric Detectors and Vector HR Pyroelectric Detectors: Note: The factory default Group for Vector Pyroelectric Detectors is Group #2. Note: The factory default Group for Vector HR Pyroelectric Detectors is Group #3. Note: Pressing the CANCEL button at any time during this process will terminate this process with no changes made.
H. The "At" (attenuation) annunciator now appears in the display. This allows you to enter a value from 0.0001 to 9999 which will become a multiplier of the actual displayed value. If no attenuator or correction factor is to be used in conjunction with the pyroelectric detector then the attenuation factor must be set to 1.000. The attenuation factors of optics can be entered into the H410 so the displayed value will automatically compensate for the amount of attenuation.
C. To select a Group, press the SELECT button when the Group you desire appears in the display (failure to press the SELECT button within 3 seconds will activate the Group shown in the display and return the S310 to its operational state). D. Press the SETUP button until the "ULtr" annunciator appears in the display. Immediately press the SELECT button to select the Ultra detector configuration program. E. The "SET CAL" (calibration) annunciator now appears in the display.
OPERATING PROCEDURES: USING THE S310 WITH VECTOR PYROELECTRIC DETECTORS: Pyroelectric detector models P25, P50, SP25, SP50, P05, and P09 are coated with a special black absorbing material which provides a very flat spectral response over a broad wavelength band. Pyroelectric detector models PHD25, PHDX25, PHDX25UV, PHD50, PHDX50, PHDX50UV, SPHD25, and SPHD50 are coated with a special high damage absorbing material which provides absorption over a broad wavelength band.
3. To Zero the Analog Needle (does not apply to the S310D): Refer to Figure 3. The black slotted button located just below the display allows screwdriver adjustment to set the analog needle to zero. This adjustment should be made before connecting a pyroelectric detector. 4. To Connect a Pyroelectric Detector: Note: Only one detector should be plugged in at any time. Refer to the drawing of the S310 rear panel in Figure 2.
7. To Select a Mode: Available pyroelectric modes are: Energy (J), Avg. Energy (J AVG), Average Power (W AVG), and Volts (V). A. To Measure Energy (J): Note: The update rate of the display is 20Hz. i. Press the MODE button (repeatedly, if necessary) until the “J” annunciator appears in the display. ii. Press the SELECT button (or wait 3 seconds) and the joules mode will automatically be activated. iii. The energy level of each laser pulse will be displayed on the LCD. B.
8. To Measure a Statistical Run of Energy Pulses: Note: Do not use AUTO range when making a statistical run. Note: Do not go from the Average Power Mode to Stats since the range will be too high. Select the range manually. Note: When using the PHF09 pyroelectric detector in the long pulse setting, a manual range must be selected when running statistics. Note: Each time a new stats run begins, data from the previous run is lost.
10. To Perform a Transfer Calibration: You can transfer a calibration from a calorimeter to a Vector pyroelectric detector using the Transfer Calibration function of the S310. To do this, please refer to the Group Settings for Vector Pyroelectric Detectors, paragraph #G. You must follow the Group Settings steps to get into the Transfer Calibration function.
CORRECTING PYROELECTRIC DETECTOR OPERATING PARAMETERS FOR USE AT DIFFERENT WAVELENGTHS: NOTE: Due to variability in the manufacturing process the absorption characteristics of the HD and P model detectors can vary in the UV region (190 to 400nm). Scientech recommends optical calibration at 266nm if the detector is to be used in the UV region instead of relying on an absorption rate in the chart at the end of this manual.
2. To Turn the Analog Needle On or Off (does not apply to the S310D): To turn the analog meter on or off, press and keep holding the RANGE button down. Then release after the meter appears or disappears. 3. To Zero the Analog Needle (does not apply to the S310D): Refer to Figure 3. The black slotted button located just below the display allows screwdriver adjustment to set the analog needle to zero. This adjustment should be made before connecting a calorimeter. 4.
7. To Select a Mode: The modes available for the calorimeters are: Average Power (W AVG) or Energy (J). A. To Measure Average Power (W AVG): Note: The speed-up circuit (differentiator) in watts mode is controlled by software and was adjusted at the factory to accommodate the type of calorimeter being used. You can change the speed-up setting to your preference.
The statistics mode will collect data on a pulse population of up to 1000 pulses. At your prompting, the indicator will display the number of pulses delivered, average energy, minimum energy, maximum energy, standard deviation, and coefficient of variation. When the statistics mode is selected, the energy mode is automatically activated regardless of the mode previously selected. Select the appropriate range for the pulse energy level to be measured.
The following are viable external triggers. The following pulses will not trigger the S310. CORRECTING ASTRAL SERIES HD CALORIMETERS OPERATING PARAMETERS FOR USE AT DIFFERENT WAVELENGTHS: NOTE: Due to variability in the manufacturing process the absorption characteristics of the HD and P model detectors can vary in the UV region (190 to 400nm).
USING THE S310 WITH ULTRA SERIES DETECTORS: The Ultra detector selected needs to be the appropriate model for the planned laser measurements. Please familiarize yourself with the operating specifications which are given in the front of this manual. Note: The default Group Setting for Ultra Detectors is Group #4. Either select Group #4 or configure another Group for Ultra Detectors and select that Group. 1.
CORRECTING ULTRA SERIES HD CALORIMETERS OPERATING PARAMETERS FOR USE AT DIFFERENT WAVELENGTHS: NOTE: Due to variability in the manufacturing process the absorption characteristics of the HD and P model detectors can vary in the UV region (190 to 400nm). Scientech recommends optical calibration at 266nm if the detector is to be used in the UV region instead of relying on an absorption rate in the chart at the end of this manual.
1. Calorimeter Watts Mode: Compare voltage to the watt reading displayed on the S310 to determine V/W constant to use when looking at the analog output. In power (watts) mode, the analog output is nominally 3 V full scale for each range. Therefore, to calculate watts from the analog output voltage: W = V/S where: V = analog output voltage (V) S = analog output sensitivity (V/W) ≈ 3 V/range (W) (for example, on the 10 mW range, S ≈ 3 V/.010 W = 300 V/W) 2.
3. Pyroelectric Watts and Joules Modes: Compare peak voltage to energy (joules) or power (watts) reading displayed on the S310 to determine V/J or V/W constant to use when looking at the analog output. In power (watts) and energy (joules) mode, the peak voltage of a laser pulse is directly proportional to the power energy level: W = Vpk/S where: Vpk = peak voltage from the analog output S = analog output sensitivity (V/W) ≈ 3 V/range (W) (for example, on the 3 mW range, S ≈ 3 V/.
CALIBRATION OF ASTRAL CALORIMETERS USING ELECTRIC SUBSTITUTION HEATING: For Astral calorimeters the electric substitution heating option must be ordered and installed at the factory when the calorimeter is purchased. It can not be retrofitted to a calorimeter at a later time. To calibrate using electric substitution heating proceed as follows. Figure 5 A. Remove the screws holding the calorimeter's ID tag and remove the plate to expose the circuit board as shown in Figure 5. B.
CALIBRATION OF LARGE APERTURE CALORIMETERS USING ELECTRIC SUBSTITUTION HEATING: Electrical substitution heating is a standard feature of large aperture calorimeters. Figure 6 Calibration with an Interface Module and S310 Indicator: A. Connect a DVM to the white jacks of the calorimeter. Refer to Figure 6. B. Measure the resistance of the substitution heater making sure to subtract the resistance of the patch cables from the total resistance measurement.
where: V = voltage applied to the heater coil Rc = substitution heater resistance from step B C = Cal coefficient 360401 = 1.018 360801 = 1.000 380401 = 0.974 380801 = 1.008 380402 = 1.024 380802 = 1.008 384UV5 = 1.021 388UV5 = 1.002 W = desired laser power in watts D. Connect the DVM to the calorimeter’s DIN connector. E. Apply the calculated voltage (V) to the electrical substitution heater. F. Record the voltage reading of the DVM (Vc). G.
Operation of Astral and Large Aperture Calorimeters with a Digital Volt Meter: Note: Whenever a large aperture calorimeter is used without an indicator the interface module is not used . The calorimeters may be used with any digital volt meter (DVM) capable of reading 5 volts full scale. Connect the output of the calorimeter to the DVM. A. Select the DC volts mode. B. Direct the laser beam on to the absorbing surface of the calorimeter. C.
The error, in theory, is only dependent upon the value of ∑dVi, that is the cumulative random error of Vi. This number should approach zero if data is carefully taken. The accuracy is also increased if the time interval, dt, is minimized. Numerical integration can yield accurate results, but is a tedious task.
Remote Interface Language: The remote interface language for the S310 is compatible with Std-IEEE488.2 and it also works with the RS232 remote interface. 1. RS-232 Connector: The RS-232 connector is a 9 pin subminiature connector on the instrument rear panel. The pin out and pin descriptions are shown below: Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8 Pin 9 Unused Data In (RXD) Data Out (TXD) DTR (is generated) Ground DSR (is ignored) RTS (is marking) CTS (is evaluated if requested) Unused 2.
4. Remote Interface Language Common Commands and Queries: Most commands and queries may be used with either the RS232 interface or the IEEE488 interface. Some commands, however, work only with the IEEE488 interface. Some commands require that a password has been entered. A few commands are archaic, but were left in because no harm was done, and they may be needed again if multi-channel units are constructed again.
RANGE_|auto Sets the range to the decimal number supplied, or to the closest legal range allowed for the current detector and configuration. If the word auto is supplied, this command activates the autorange feature if it is supported for the current detector and configuration. RANGE? The RANGE query returns the decimal number between 1 and the maximum range of the instrument. The meaning of the number varies, depending upon the type of detector, and the configuration of the instrument.
DUMP? If statistics have been collected from the front panel, or by the COL or COL? commands, this command returns all of the data values in the collection. If no statistics have been collected, it does nothing. BAUD_ If the takes any of the values 300, 1200, 2400, 9600, or 19200; or any of their abbreviations 3, 12, 24, 96, 192, this command sets the RS232 baud rate to the corresponding value.
*RCL_ This is the IEEE488.2 common command. It takes the single numeric argument [1-4], and restores the instrument configuration to that configuration stored in the corresponding save area. It also places the IEEE interface into the OCIS and OQIS states. COUNT_ Sets the number of pulses making up each average in average energy mode. COUNT? Returns the number of pulses making up each average in average energy mode.
5. IEEE488 Specific Commands: These commands may be used only from the IEEE488.2 interface. They are all members of the collection of the so-called "common Commands" described in the IEEE488.2 standard. *CLS Clears the Standard Event Status Register and forces the device into Operation Complete Command Idle state. *ESR? Returns a decimal number which is the value of the Standard Event Status Register. Reading the register clears it.
