6243/44 DC Voltage Current Source/Monitor Operation Manual
7.1.3 Test Methods

(2) Voltage source measurement test
1. Connect the 6243 and the DMM (Digital Multi-Meter) as shown in Figure 8-1
(a).
2. Set the DMM to DCV, auto range, and the integration time at 10 PLC or longer.
3. Set the 6243 to the DC source mode, free-run, and the integration time at 10 PLC
or longer.
4. Select voltage source voltage measurement and Operate.
5. With ZERO and F.S generated in the 320 mV range to 110 V range, verify that
the difference between the source set value and the DMM measured value and
the difference between the 6243 measured value and the DMM measured value
are within the accuracy described in Section 9.1, “6243 Specifications.”
(3) Current source measurement test
1. Connect the 6243 and the DMM as shown in Figure 8-1 (b).
2. Set DMM to DCI, auto range, and the integration time at 10 PLC or longer.
3. Set the 6243 to DC source mode, free run, and the integration time at 10 PLC or
longer.
4. Select current source current measurement and Operate.
5. With ZERO and F.S generated in the 30 A range to 2 A range, verify that the
difference between the source set value and the DMM measured value and the
difference between the 6243 measured value and the DMM measured value are
within the accuracy described in Section 9.1, “6243 Specifications.”
However, if 6581 is used as DMM, the F.S of the 2 A range should be 1 A.
NOTE: If the result of this test does not fall within the accuracy specifications, calibrate
the 6243/44 as outlined in Section 8.1, “6243 Calibration” or contact an ADC
CORPORATION sales representative for calibration or servicing.
