PARAMETER MENU

Enter the desired Display Intensity Level (0-15) by

using the arrow keys. The display will actively dim or

brighten as the levels are changed. This parameter also

appears in Quick Programming Mode when enabled.

DISPLAY INTENSITY LEVEL

The meter has been fully calibrated at the factory.

Scaling to convert the input signal to a desired display

value is performed in Module 1. If the meter appears to be

indicating incorrectly or inaccurately, refer to

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.

CALIBRATION









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.  and

PAR

can be chosen to exit the calibration mode without any changes taking place.

Then perform the following procedure:

1. Use the arrow keys to display   and press

PAR.

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

4. Press

PAR and  will appear on the display for about 10 seconds.

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.)

6. Press

PAR and  will appear on the display for about 10 seconds.

7. When  appears, press

PAR twice.

8. If the meter is not field scaled, then the input display should match the value

of the input signal.

9. Repeat the above procedure for each input range to be calibrated.

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.

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.

PAXD - Input Calibration

PAXH - Input Calibration

PAXP - Input Calibration

Before starting, verify that the precision signal source is connected to the

correct terminals and ready. Allow a 30 minute warm-up period before

calibrating the meter.  and

PAR can be chosen to exit the calibration mode

without any changes taking place.

Then perform the following procedure:

1. Use the arrow keys to display   and press

PAR.

2. Choose the range to be calibrated by using the arrow keys and press

PAR.

( and

PAR can be chosen to exit the calibration mode without any changes

taking place.)

3. When the zero range limit appears on the display, apply the appropriate:

- Voltage range: dead short applied

- Current range: open circuit

4. Press

PAR and  will appear on the display for about 10 seconds.

5. When the top range limit appears on the display, apply the appropriate:

- Voltage range: 10 VDC

- Current range: 20 mADC

6. Press

PAR and  will appear on the display for about 10 seconds.

7. When  appears, press

PAR twice.

8. If the meter is not field scaled, then the input display should match the value

of the input signal.

9. Repeat the above procedure for each input range to be calibrated.

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)

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.  and

PAR can be chosen to exit the calibration

mode without any changes taking place.

Then perform the following procedure:

1. Press the arrow keys to display   and press

PAR.

2. The meter displays . Use the arrow keys to select the range that matches

the Signal Jumper setting. Press

PAR.

3. Apply the signal matching the meter prompt.

4. Press

PAR and  will appear on the display, wait for next prompt.

5. Repeat steps 3 and 4 for the remaining three prompts.

6. When  appears, press

PAR twice.

7. If the meter is scaled to show input signal, the Input Display should match

the value of the input signal in the Display Mode.

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.

RESTORE FACTORY DEFAULTS

Use the arrow keys to display   and press

PAR.

The meter will display  and then return to  .

Press

DSP key to return to Display Mode. This will

overwrite all user settings with the factory settings.
