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: mV input or output error limits
Calibration - Procedures (CJ input)
1. Connect the instrument to the calibration equipment
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: 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.
