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
6. Make sure that the error is in the specified limits
(Table 10 or Table 11).
Table 10: mV input error limits
Table 11: Volts (V) input error limits
Calibration - Procedures (mA input)
1. Connect the instrument to the calibration equipment
(Figure 4).
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
)
