3. To make sure that the calibration is correct, select the 

applicable ohms input task (Table 2).

4. Make a 4 wire connection to the applicable standard 

resistor (Table 10) and measure the value (Figure 1)

5. Make sure that the error is in the specified limits 

(Table 10).

Table 10: 

Ohms input error limits

Calibration - Procedures (Ohms 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 for each range. 

• Range: 0-399.9

Ω

• Range: 400

Ω

The display shows the applicable instructions to
calibrate each range.

4. To make sure that the calibration is correct, select the 

applicable ohms output task (Table 2).

5. Supply the specified values (Table 11). Make sure that 

the error is in the specified limits.

Table 11: 

Ohms output error limits

Calibration - Procedures (mA input)

1. DPI 812 only. Connect the instrument to the calibration 

equipment (Figure 5). 

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 mA input task (Table 2) and apply these 
values:

• mA: -55, -40, -24, -18, -12, -6, 0 (open circuit)

Then mA: 0, 6, 12, 18, 24, 40, 55.

5. Make sure that the error is in the specified limits

(Table 12)

Table 12: 

mA input error limits 

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.
