12-2. Equipment Needed to Calibrate:
1. A dimensional standard
2. A regulated ± 15 Vdc power supply
3. A voltmeter accurate to one millivolt
4. An insulated adjusting tool (“tweaker”) Kaman P/N 823977-T007
5. A calibration cover plate
NOTE: When you do a system calibration, if at all possible, do it with the system
installed in the application fixture at normal operating temperatures. This eliminates
any sift in system output caused by moving the system from a calibration fixture to
the application fixture (translation error).
12-3. Calibration Procedure Overview:
12.3a. Calibration involves five steps:
1. Null the Target
2. Monitor the output of axis 1 - Adjust for 0.000 volts output
3. Move the target to full displacement – Adjust for full output voltage
4. Return the target to the null position and check for an output of 0V±10mV
5. Repeat for axis 2
The following information details these five steps.
12-4. Calibration Steps:
12-4a. Install the sensors in the application fixture (or calibration fixture) and accurately
establish the null position for the target (see paragraph 11-3).
WARNING: Avoid contacting the eyes with silicone heat sink compound. It will
cause temporary irritation. It also stains clothing.
12-4b. Withdraw the four screws securing the cover plate and remove it. Silicone heat
sink compound has been liberally spread between the mica pad and the hybrid case.
12-4c. Install the calibration cover plate, power up the system and allow a 20 minute
warm-up period. Monitor system output.
