Calibration - Procedures (mV or Volts output)
1. Connect the instrument to the calibration equipment
(Figure 2).
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 two-point
calibration (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 output task and range (Table 2).
5. Then set the output values that are applicable to the
calibration:
• mV: 0, 30, 60, 90, 120
OR
• Volts (V): 0, 3, 6, 9, 12
6. Make sure that the error is in the specified limits
(Table 13 or Table 14).

Calibration - Procedures (mA output)
1. Connect the instrument to the calibration equipment
(Figure 3).
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 two-point
calibration (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 mA output task (Table 2) and set these
output values:
• mA: 0.1, 4, 12, 20, 24
5. Make sure that the error is in the specified limits
(Table 15).

Calibration - Procedures (IDOS UMM)
Refer to the user manual for the IDOS UMM.
When the calibration is complete, the instrument
automatically sets a new calibration date in the UMM.
