PROCEDURES: DC mV/Volts (measure) 5.7
Do the procedure as follows:
1. Connect the applicable calibration equipment (See
Table 5-1
).
2. Let the equipment get to a stable temperature (minimum: 5
minutes since the last power on).
3. Use the calibration menu (
See Section 5.4
) to do a three-point
calibration.
(-FS, Zero and +FS) for the applicable set of ranges:
mV (measure) ranges Volts (measure) ranges
200 mV 20 V
2000 mV 30 V
4. Check the calibration is correct:
•
Select the applicable Millivolts or Voltage (measure) function.
• Apply the input values that are applicable to the Calibration:
mV: -2000, -1000, -200, -100, 0 (short circuit)
mV: 0, 100, 200, 1000, 2000
Volts (V): -30, -21, -20, -10, -5, 0 (short circuit)
Volts (V): 0, 5, 10, 20, 21, 30.
• Check that the error is within limits (
See Table 5-4
and
Table
5-5 ).
