It is recommended that Input Calibration be performed first.

1. With meter power removed, set the Input Range Jumper for 20 V, the Couple

Jumper for DC, and set the Signal Jumper for voltage by removing the jumper.

2. Connect a wire (short) between Volt (terminal 6) and COMM (terminal 4).
3. Apply meter power.
4. In Module 1, program as follows: Range:

7. The readout displays the DC coupled zero input, record the value.
8. Remove the meter power and set the Couple Jumper to AC by removing the

jumper.

9. Maintaining the short between terminals 4 and 6, reapply the meter power.

10. Keeping all programming the same, view the Input Display.
11. The readout now displays the AC coupled zero input, record the value.

AC Couple Offset Calibration - PAXH

PAXS - Input Calibration

PAXT - 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.

Before starting, connect -SIG (terminal 4) to COMM (terminal 5). This

allows a single ended signal to be used for calibration. Connect the calibration
signal to +SIG (terminal 3) and -SIG (terminal 4). Verify the Input Range
jumper is in the desired position. Allow a 30 minute warm-up period before
calibrating the meter.

can be chosen to exit the calibration mode

without any changes taking place. Perform the following procedure:
1. Press 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 0 mV bSIG

and -SIG.

4. Press

PAR

and ---- will appear, wait for next prompt.

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

+SIG and -SIG voltage (20 mV or 200 mV).

6. Press

PAR

and ---- will appear, on the display for about 10 seconds.

7. When

appears, press

PAR

twice to exit programming.

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 -SIG to COMM

connection and external signal source.

10. Restore original configuration and jumper settings.

100 OHM RTD Range Calibration

1. Set the Input Range Jumper to 100 ohm.
2. Use the arrow keys to display

link. Wait 10 seconds, then press

PAR

4. At

, apply a precision resistance of 300 ohms (with an accuracy of

0.01% or better) using a three wire link, to terminals 3, 4 and 5. Wait 10
seconds, press

PAR

5. Connect the RTD, return to the Display Mode and verify the input reading

(with 0 Display Offset) is correct. If not correct repeat calibration.

THERMOCOUPLE Range Calibration

4. Return to the Display Mode.
5. Continue with Ice Point Calibration.

ICE POINT Calibration

Remove all option cards or invalid results will occur.

2. The ambient temperature must be within 20

C to 30

3. Connect a thermocouple (types T, E, J, K, or N only) with an accuracy of 1

or better to the meter.

4. Verify the readout Display Offset is 0, Temperature Scale is

C, Display

Resolution is 0.0, and the Input Range is set for the connected thermocouple.

5. Place the thermocouple in close thermal contact to a reference thermometer

probe. (Use a reference thermometer with an accuracy of 0.25

C or better.)

The two probes should be shielded from air movement and allowed sufficient
time to equalize in temperature. (A calibration bath could be used in place of
the thermometer.)

6. In the Normal Display mode, compare the readouts.
7. If a difference exists then continue with the calibration.
8. Enter Module 9, use the arrow keys to display

11. Return to the Display Mode and verify the input reading (with 0 Display

Offset) is correct. If not correct repeat steps 8 through 10.

Warning: Calibration of this meter requires precision instrumentation

operated by qualified technicians. It is recommended that a
calibration service calibrates the meter.

Before selecting any of the calibration procedures, the input to the meter

must be at 0 mV or 0 ohms. Set the digital filer in Module 1 to 1 second. Allow
a 30 minute warm-up period before calibrating the meter. The
