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.

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.

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.

ANALOG OUTPUT CARD CALIBRATION

Before starting, verify that the precision voltmeter (voltage output) or current

meter (current output) is connected and ready. Perform the following procedure:

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

PAR.

2. Use the arrow keys to choose  and press

PAR.

3. Using the chart below, step through the five selections to be calibrated. At

each prompt, use the PAX arrow keys to adjust the external meter display to

match the selection being calibrated. When the external reading matches, or

if this range is not being calibrated, press

PAR.

4. When  appears remove the external meters and press

PAR twice.

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, 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 input channel/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 the top range limit will appear on the display after

approximately 1 second.

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

- Voltage range: 10 VDC

- Current range: 20 mADC

6. Press

PAR and .  will appear on the display after approximately 1

second.

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.
