6247G/6247C DC Voltage Current Source/Monitor Operation Manual
7.3 Test Method
7-3
Current source and measurement test (30
A to 300 mA range)
1. Connect the 6247G/6247C and a DMM (Digital Multi-Meter) as shown in Figure
8-1 (c).
2. Set the DMM to DCI, auto range and integration time of 10 PLC or longer.
3. Set the 6247G/6247C to DC source mode, AUTO trigger mode and integration
time of 200 ms.
4. Select current source current measurement, and set the output to Operate.
5. With ZERO and
Full Scale generated in the 30
A range to the 300 mA range,
verify that the difference between the source value and the DMM measured value
is within the accuracy described in Chapter 9, "SPECIFICATIONS."
NOTE:
If the result of this test does not fall within the accuracy specifications, cali-
brate the 6247G/6247C as outlined in Chapter 8, "CALIBRATION" or con-
tact an ADC CORPORATION sales representative for the calibration or
servicing.
