9102S Dry-Well Calibrator DC Power Operation 3.4 DC Power Operation This instrument is equipped with a DC power option. The DC option requires a power source that delivers 12 VDC at 3 amps. WARNING: A fire may occur if a short circuit occurs along the input cord and no protective devices are on the DC input source. For short circuit protection using a battery, a fuse is required at the battery terminals. The DC power socket is located on the rear panel of the instrument near the AC power jack.
Parts and Controls Rear Panel 4 Parts and Controls The user should become familiar with the dry-well calibrator and its parts: (See Figure 2 on this page and Figure 3 on next page). 4.1 Rear Panel Power Cord - The removable power cord, (Figure ) attaches to the back side of the instrument. It plugs into a standard 115 VAC (optional 230 VAC) grounded socket. Figure 2 Back Panel DC Power Jack - The calibrator can be used with a DC power source. The DC input jack requires 12V and 3.3 amps.
9102S Dry-Well Calibrator Front Panel corners of the instrument are provided for airflow. The area around the calibrator must be kept clear to allow for adequate ventilation. The air is directed from the front to the back. Allow 6 inches of open space around the calibrator to allow adequate ventilation. RS-232 - The RS-232 serial port provides a means for connecting the instrument to a computer or a printer using the included serial cable.
Parts and Controls Accessories Controller Keypad - The four button keypad allows easy setting of the set-point temperature. The control buttons (SET, d, u, and EXIT) are used to set the calibrator temperature set-point, access and set other operating parameters, and access and set calibration parameters. Setting the control temperature is done directly in degrees of the current scale. It can be set to one-tenth of a degree Celsius or Fahrenheit.
General Operation Changing Display Units 5 General Operation 5.1 Setting the Temperature Section 6.2, Temperature Set-point, on page 19 explains in detail how to set the temperature set-point on the calibrator using the front panel keys. The procedure is summarized here. 1. Press “SET” twice to access the set-point value. 2. Press u or d to change the set-point value. 3. Press “SET” to program in the new set-point. 4. Press and hold “EXIT” to return to the temperature display.
Controller Operation Temperature Set-point 6 Controller Operation This chapter discusses in detail how to operate the dry-well temperature controller using the front control panel. Using the front panel key-switches and LED display the user may monitor the well temperature, set the temperature set-point in degrees C or F, monitor the heater output power, adjust the controller proportional band, and program the calibration parameters, operating parameters, and serial interface configuration.

S 6.2.2 Accept selected set-point memory Set-point Value The set-point value may be adjusted after selecting the set-point memory and pressing “SET”. 4 50.
9102S Dry-Well Calibrator Scan 6.3 Scan The scan rate can be set and enabled so that when the set-point is changed the dry-well heats or cools at a specified rate (degrees per minute) until it reaches the new set-point. With the scan disabled the dry-well heats or cools at the maximum possible rate. 6.3.1 Scan Control The scan is controlled with the scan on/off function that appears in the main menu after the temperature scale units.
Controller Operation Heater Power changed. The set-point resistance is used to perform a calibration adjustment using the Callendar-Van Dusen R versus T curve fit (see Section , Calibration Procedure). The instrument must be at temperature and stable prior to taking the set-point resistance reading. The set-point resistance can be displayed by pressing the “SET” and d simultaneously. The set-point resistance is displayed as follows. SrES SrES flashes for two seconds and then the whole number 99.
9102S Dry-Well Calibrator Proportional Band 6.7 Proportional Band In a proportional controller such as this, the heater output power is proportional to the well temperature over a limited range of temperatures around the set-point. This range of temperature is called the proportional band. At the bottom of the proportional band, the heater output is 100%. At the top of the proportional band, the heater output is 0.
Controller Operation Serial Interface Parameters 6.8 Controller Configuration The controller has a number of configuration and operating options and calibration parameters which are programmable via the front panel. These are accessed from the secondary menu after the proportional band function by pressing “SET”. Pressing “SET” again enters the first of three sets of configuration parameters — operating parameters, serial interface parameters, and calibration parameters.
9102S Dry-Well Calibrator Serial Interface Parameters 6.11.1 Baud Rate The baud rate is the first parameter in the menu. The baud rate setting determines the serial communications transmission rate. The baud rate parameter is indicated by, bAUd Flashes bAUd for one second and then displays the setting 2400b Current baud rate The BAUD rate of the serial communications may be programmed to 300, 600, 1200, 2400 (default), 4800, or 9600 BAUD. Use the up or down arrows to change the BAUD rate value.
Controller Operation Calibration Parameters FULL Current duplex mode setting The mode may be changed using the up or down arrows (u d). HALF New duplex mode setting Press “SET” to accept the new setting or “EXIT” to abort the operation and skip to the next parameter in the menu. 6.11.4 Linefeed The final parameter in the serial interface menu is the linefeed mode.
The calibration parameters are accessed by pressing “SET” after the name of the parameter is displayed. The value of the parameter may be changed using the up or down arrow. After the desired value is reached, press “SET” to set the parameter to the new value. Pressing “EXIT” causes the parameter to be skipped ignoring any changes that may have been made. 6.12.1 R0 This probe parameter refers to the resistance of the control probe at 0°C.
6.12.3 DELTA This probe parameter characterizes the curvature of the resistance-temperature relationship of the sensor. The value of this parameter is set at the factory for best instrument accuracy. DeLta Flashes for one second and then the DELTA setting is displayed 0.0000 Current DELTA setting To change the DELTA setting, press the up or down arrows. 0.1000 New DELTA setting To accept the new setting, press “SET”. Press “EXIT” to continue without storing the new value.
Digital Communication Interface RS-232 Connection 7 Digital Communication Interface This instrument is capable of communicating with and being controlled by other equipment through the digital serial interface. With a digital interface, the instrument may be connected to a computer or other equipment. This allows the user to set the set-point temperature, monitor the temperature, and access any of the other controller functions, all using remote communications equipment.
9102S Dry-Well Calibrator Interface Commands 7.2 Interface Commands The various commands for accessing the calibrator functions via the digital interface are listed in this section (see Table 4 on this page). These commands are used with the RS-232 serial interface. The commands are terminated with a carriage-return character (CR, ASCII 13). The interface makes no distinction between upper and lower case letters, hence either may be used.

Test Probe Calibration Dry-well Characteristics 8 Test Probe Calibration For optimum accuracy and stability, allow the calibrator to warm up for 10 minutes after power-up and then allow adequate stabilization time after reaching the set-point temperature. After completing operation of the calibrator, allow the well to cool by setting the temperature to 25°C for one-half hour before switching the power off. 8.1 Calibrating a Single Probe Insert the probe to be calibrated into the well of the instrument.
Calibration Procedure Calibration Procedure 9 Calibration Procedure Note: This procedure is to be considered a general guideline. Each laboratory should write their own procedure based on their equipment and their quality program. Each procedure should be accompanied by an uncertainty analysis also based on the laboratory’s equipment and environment. Sometimes the user may want to calibrate the dry-well to improve the temperature set-point accuracy.
