TP2 (+120 VDC to 140 VDC) VDC VAC ( < .005 VAC)
TP3 +5 VDC ( ± .15 VDC) VDC VAC ( < .005 VAC)
TP9 +15 VDC ( ± .30 VDC) VDC VAC ( < .005 VAC)
TP12 -15 VDC ( ± .30 VDC) VDC VAC ( < .005 VAC)
TP13 +3.3 VDC ( ± .15 VDC) VDC VAC ( < .005 VAC)
TP16
+2.5 VDC ( ± .10 VDC) VDC VAC ( < .005 VAC)
If this maintenance is just prior to a RATA or is being done as part of an Emergency Repair:
1. Compare the System Properties to the last recorded parameters.
2. Check and adjust the Pressure calibration.
3. Check and adjust the External Temperature calibration.
4. Check and adjust the Analog Outputs.
Force the monitor through a calibration and record the results.
