6253 DC Voltage Current Source/Monitor Operation Manual
6.3 Test Method
6-3
Current source and measurement test (2 A)
1. Connect the 6253 and a DMM as shown in Figure 7-1 (c)
The resistance value is as follows:
2. Set the DMM to DCV, auto range and integration time of 10 PLC or longer.
3. Set the 6253 to DC source mode, AUTO trigger 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 2 A range, verify that the
differences between the source values and the current-converted values that is
obtained by “DMM measured value/Standard resistance value” are within the
accuracies described in Chapter 8, “SPECIFICATIONS.”
NOTE: If the result of this test does not fall within the accuracy
specifications, calibrate the 6253 as outlined in Chapter 7,
“CALIBRATION” or contact an ADC CORPORATION sales
representative for the calibration or servicing.
Standard resistance value
2 A 100 mΩ
