Calibration Procedures (CH1/CH2): DC mV/Volts (measure)
Note:
When recalibrating ‘measure’ functions for this
range, any adjustment will affect the corresponding
source function calibration. The source function
must, therefore, be re-calibrated after adjusting the
measure function.
Perform the calibration as follows:
1.
Connect the applicable calibration equipment specified
in Table 10-1; for example see
Section 2.8
.
2.
Let the equipment get to a stable temperature
(minimum: 5 minutes since the last power on).
3.
Use the calibration menu (Ref:
Section 10.2
) 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 (Ref:
Section 2.8
).
•
Apply the input values that are applicable to the
calibration:
mV: -1995, -1000, -195, -100, 0 (short circuit)
mV: 0, 100, 195, 1000, 1995
Volts (V): -30, -21, -20, -10, -5, 0 (short circuit)
Volts (V): 0, 5, 10, 20, 21, 30.
Check that the error is within the specified limits (Ref:
