7.3.2
Voltage Source and Voltage Measurement Test
1. Connect the 4601 and DMM (Digital Multimeter) as shown in Figure 8-1 (a).
2. Set DMM to DCV, auto range and integration time of 10 PLC.
3. Set the 4601 to the DC source mode, AUTO sampling and integration time of 200 ms.
4. Set the output status to Operate.
5. With ZERO and
Full Scale generated in the 5 V to 300 V range, verify that the difference between
the source value and the DMM measured value and the difference between the source value and the
voltage measured value of the 4601 are within the accuracies described in Chapter 9, "SPECIFICA-
TIONS."
7.3.3
Current Measurement Test
1. Connect the 4601 and a current source standard as shown in Figure 8-1 (b).
2. Set the 4601 to the DC source mode, AUTO sampling and integration time of 200 ms.
3. Set the voltage source to 0 V and the current limit to
320
A.
4. Set the output status to Operate.
5. Generate 0 A, +300
A and -300
A from the standard, and verify that the difference between the
source value and the measured current of the 4601 is within the accuracy described in Chapter 9,
"SPECIFICATIONS."
6. Change the current limit value from
3.2 mA to
10.2 A, change the source value of the standard to
ZERO and
Full Scale, and check the accuracies in the same way as Step 4 and Step 5.
In the 300 mA to 10 A range, check the positive current by +0.1 A and the negative current by - FS.
The connection in the 3 A range and the 10 A range is shown in Figure 8-4 (c).
7.3.4
Current Limit Test
Perform this test after the current measurement test is complete.
1. Connect the 4601 and a current source standard as shown in Figure 8-2 (d).
2. Set the 4601 to the DC source mode, AUTO sampling and integration time of 200 ms.
3. Set the voltage source to +5 V and the current limit to
300
A.
4. Set the output status to Operate.
5. Ge5 V and -5 V, and verify that the difference between the current limit and the measured
current of the 4601 is within the accuracy described in Chapter 9, "SPECIFICATIONS."
6. Change the current limit from
3.0 mA to
10.0 A, and check the positive and negative current limit
accuracies in the same way as Step 4 and Step 5.
In the 300 mA to 10 A range, check the positive current limit by +0.1 A and the negative current limit
by - FS.
