IDOS ... UMM only. To calibrate the specified IDOS UMM.
Refer to the user manual for the IDOS UMM.
Calibration Due: To set the date of the next
calibration for the instrument.
After the specified calibration date, there is a
warning message. There is a selection box to stop
the warning.
To change the calibration PIN (Personal
Identification Number).
When you select a channel, the display shows the
applicable instructions to complete the calibration.
When the calibration is complete, select Calibration Due
and set the new calibration date for the instrument.

Calibration - Procedures (mV or Volts input)

1. Connect the instrument to the calibration equipment
(Figure 1).
2. Let the equipment get to a stable temperature
(minimum: 5 minutes since the last power on).
3. Use the calibration menu (Table 9) to do a three-point
calibration (-FS, Zero and +FS). The display shows the
applicable instructions to complete the calibration.
4. To make sure that the calibration is correct, select the
applicable Volts input task and range (Table 2).
5. Then apply the input values that are applicable to the
calibration:
• mV: -120, -60, -30, 0 (short circuit)
Then mV: 0, 30, 60, 120
OR
• Volts (V): -30, -15, -5, 0 (short circuit)
Then volts (V): 0, 5, 15, 30

4. To make sure that the calibration is correct, select the
applicable mA input task (Table 2) and apply these
values:
• mA: -55, -40, -24, -18, -12, -6, 0 (short circuit)
Then mA: 0, 6, 12, 18, 24, 40, 55.
5. Make sure that the error is in the specified limits
