Ohms Adjustment
1. Connect the ProcessMeter to the volt/ohm output of the 5522A calibrator.
2. Turn the UUT’s switch to
V.
3. Press and hold the Calibration Button for approximately 2 seconds. The unit will beep
(see Figure 11).
Note
Pressing the Calibration Button puts the ProcessMeter into and out of
calibration mode. The ProcessMeter will remain in calibration mode until
the unit is turned off or the calibration button is pressed a second time.
CAL appears in the bottom display when the ProcessMeter is in calibration
mode.
4. Apply the resistances listed below. Press  after each sourced value appears.
Do not alter the sourced value while the display reads Busy.
Applied resistances:
• 0 Ω
• 400 Ω
• 4 kΩ
• 40 kΩ
• 400 kΩ
• 4 MΩ
• 40 MΩ
5. When Store is displayed, press  to store the calibration value.
Diode Adjustment
1. Connect the ProcessMeter to the volt/ohm output of the 5522A calibrator.
2. Turn the UUT’s switch to
V.
3. Press J (BLUE) to enter the diode function.
4. Press and hold the Calibration Button for approximately 2 seconds. The unit will beep
(see Figure 11).
Note
Pressing the Calibration Button puts the ProcessMeter into and out of
calibration mode. The ProcessMeter will remain in calibration mode until
the unit is turned off or the calibration button is pressed a second time.
CAL appears in the bottom display when the ProcessMeter is in calibration
mode.
Before applying 0 V dc, the 5522A must be range locked in the 3.3 V range.
Impedance of 330 mV range changes the 0 V point.
5. Apply 0 V dc. Press  after the sourced value appears. Do not alter the sourced
value while the display reads Busy.
6. Apply 1 V dc. Press  after the sourced value appears. Do not alter the sourced
value while the display reads Busy.
7. When Store is displayed, press  to store the calibration value.
