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

applicable mV input or output task (Table 2) and apply 
the necessary values:

• mV input: -10, -5, 0 (short circuit)

Then mV: 5, 10, 20, 50, 100

• mV output: -10, -5, 0, 5, 10, 20, 50, 100
5. Make sure that the error is in the specified limits 

(Table 10)

Table 10: mV input or output error limits

Calibration - Procedures (CJ 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 one-point 

calibration (+FS). The display shows the applicable 
instructions to complete the calibration.

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

applicable T1 input task (Table 2).

5. Make sure that the DPI 821/822 gives a probe 

temperature that agrees with the temperature on 
the digital thermometer ±0.2°F (0.1°C).

Calibration - Procedures (mA input)

1. DPI 822 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 two-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 (short circuit)

Then mA: 0, 6, 12, 18, 24, 40, 55.

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

(Table 11)

Table 11: 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.
