75% and reflects 25% of the beam. If the H410 is set up to measure the reflected beam the attenuation could be set up as follows: • An attenuation factor of 1 would display the value of the reflected beam. • An attenuation factor of 3 would display the value of the transmitted beam. • An attenuation factor of 4 would display the value of the source. To enter into the attenuation factor mode: A. Press the MODE button to start a menu cycle of W, CAL and Attn. B.
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 4 A. Remove the screws holding the calorimeter's ID tag and remove the plate to expose the circuit board as shown in Figure 4. B.
CALIBRATION OF LARGE APERTURE CALORIMETERS USING ELECTRIC SUBSTITUTION HEATING: Electrical substitution heating is a standard feature of large aperture calorimeters. Figure 5 Calibration with an Interface Module and H410 Indicator: A. Connect a DVM to the white jacks of the calorimeter. Refer to Figure 5. B. Measure the resistance of the substitution heater making sure to subtract the resistance of the patch cables from the total resistance measurement.
Calibration without an Interface Module and H410 Indicator: Note: Whenever a large aperture calorimeter is used without an indicator the interface module is not used. For this procedure you will need to make an adapter cable to go from the calorimeter’s DIN connector to the DVM. The voltage output is on pin 1 of the DIN connector and should be connected to the positive side of the DVM. Ground is on pin 3 and should be connected to the negative side. Pin 2 is not used. Refer to Figure 5. A.
DETECTOR OPERATION WITHOUT AN INDICATOR: Pyroelectric Detectors: Standard and SP Models: Pyroelectric detectors can be operated with a 1MΩ input oscilloscope. The peak voltage shown on the oscilloscope can be divided by the V/J output sensitivity of the detector to calculate energy. Astral TM and Large Aperture Calorimeters: Cable Requirements: Astral calorimeters are powered up by the indicators.
Operation of Astral and Large Aperture Calorimeters with an Analog Chart Recorder: Note: Whenever a large aperture calorimeter is used without an indicator the interface module is not used. Calorimeter Response: The response of a calorimeter to a single pulse input as displayed by a chart recorder appears below.
Initial Voltage Interpolation: A method used to eliminate the tedious numerical integration task is to project the thermal decay envelope on to the voltage axis, determine the 1/e decay time constant T, and estimate the total energy value (E): E = (Vo/S) x T The change from thermal absorption to thermal transport phenomena near the peak causes difficulty in accurately projecting the envelope on to the voltage axis introducing an error, dVo.
