Procedures: mV/Volts 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 mV or Volts input task (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 12
or Table 13).

Procedures: mV/Volts output

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 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 mV or Volts output task (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 14
or Table 15).

Procedures: Hz input/output

1. Connect the instrument to the calibration equipment
(Figure 6).
2. Let the equipment get to a stable temperature (minimum:
5 minutes since the last power on).
3. Set up the equipment with these conditions:
Frequency meter:
Signal generator:
DPI 880:
4. Use the calibration menu (Table 9) to do the calibration.
The display shows the applicable instructions to complete
the calibration.
5. To make sure that the calibration is correct, set up the
equipment to do one of these calibration checks:
• Hz input calibration check (Figure 6):
Frequency meter:
Signal generator:
DPI 880:
• Hz output calibration check (Figure 6):
Frequency meter:
DPI 880:
6. Measure or supply the specified values (Table 16/17): Hz
then kHz. Make sure that the error is in the specified
limits.
