Troubleshooting before attempting to calibrate the meter.
When recalibration is required (generally every 2 years), it should only be
performed by qualified technicians using appropriate equipment. Calibration
does not change any user programmed parameters. However, it may affect the
accuracy of the input signal values previously stored using the Apply (
Scaling Style.
Calibration may be aborted by disconnecting power to the meter before
exiting Module 9. In this case, the existing calibration settings remain in effect.
PAXD - Input Calibration
WARNING: Calibration of this meter requires a signal source with an
accuracy of 0.01% or better and an external meter with an accuracy
of 0.005% or better. Resistance inputs require a resistance
substitution device with an accuracy of 0.01% or better.
Before starting, verify that the Input Ranger Jumper is set for the range to be
calibrated. Also verify that the precision signal source is connected and ready.
Allow a 30 minute warm-up period before calibrating the meter.

2. Choose the range to be calibrated by using the arrow keys and press PAR.
3. When the zero range limit appears on the display, apply the appropriate:
- Voltage ranges: dead short applied
- Current ranges: open circuit
- Resistance ranges: dead short with current source connected

5. When the top range limit appears on the display, apply the appropriate:
- Voltage ranges: top range value applied (The 300 V range is the exception.
It is calibrated with a 100 V signal.)
- Current ranges: top range value
- Resistance ranges: top range value (The ohms calibration requires
connection of the internal current source through a resistance substitution
device and the proper voltage range selection.)

PAXH - Input Calibration
WARNING: In the PAXH, DC signals are used to calibrate the AC
ranges. Calibration of the PAXH requires a DC voltmeter with an
accuracy of 0.025% and a precision DC signal source capable of:
1. +1% of full scale, DC
2. -1% of full scale, DC
3. +100% of full scale, DC; (300 V range = +100 V calibration)
4. -100% of full scale, DC; (300 V range = -100 V calibration)
and PAR
Before starting, verify the Input Range and Signal Jumpers are set for the
range to be calibrated and the Couple jumper is installed for DC. Also verify the
DC signal source is connected and ready. Allow a 30 minute warm-up period
before calibrating the meter.

8. Repeat the above procedure for each range to be calibrated or to recalibrate
the same range. It is only necessary to calibrate the input ranges being used.
9. When all desired calibrations are completed, remove the external signal
source and restore original configuration and jumper settings. If AC is being
measured, continue with AC Couple Offset Calibration.
