12.3 Calibration Steps
12.3.1 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 eye contact with the silicone heat sink compound as it will cause
temporary irritation.
12.3.2 Remove the four screws securing the cover plate and remove it. Silicone heat
sink compound has been liberally spread between the hybrid case and the cover plate.
12.3.3 Install the calibration cover plate, power up the system and allow a 20 minute
warm-up period. Monitor system output to verify stability.
NOTE
: Output at null should be ideally 0.000 V. In practice, this is very difficult to
achieve since it requires positioning the target to within micro-inches. Thermal
expansion caused by simply placing a hand on the calibration fixture can cause more
movement than a micro-inch. Get as close to 0.000 V as possible, not to exceed ± 10
mV.
12.3.4 To adjust for 0.000 V:
Monitor the output of axis 1.
Using the adjusting tool, adjust the zero control for axis 1 (Figure 14) for 0.000 V
output.
