7.3.5
Reference Cell Current Measurement Test
1. Connect the 4601 and a current source standard as shown in Figure 8-2 (e).
2. Set the 4601 to the DC source mode, AUTO sampling and integration time of 200 ms.
3. Set ADC3 measurement to the reference current function Ir and select the 3 mA range.
4. Set the output status to Operate.
5. Generate ZERO and
FS from the standard, and verify that the difference between the measured cur-
rent of the 4601 in the 3 mA to 300 mA range and the setting value of the standard is within the accu-
racy described in Chapter 9, "SPECIFICATIONS."
-FS in the 300 mA range is checked by -30 mA.
7.3.6
Pt Temperature Measurement Test
1. Connect the 4601 and a resistance source standard as shown in Figure 8-2 (f).
2. Set the 4601 to the DC source mode, AUTO sampling and integration time of 200 ms.
3. Set ADC3 measurement to the Pt1 or Pt2 function.
4. Set the output status to Operate.
5. Set the resistance of the standard to 100
, and verify that the measured value of the 4601 is within
the accuracy described in Chapter 9, "SPECIFICATIONS."
The temperature at the resistance is as follows:
7.3.7
AD590 Temperature Measurement Test
1. Connect the 4601 and a current source standard as shown in Figure 8-3 (g).
2. Set the 4601 to the DC source mode, AUTO sampling and integration time of 200 ms.
3. Set ADC3 measurement to the Ad1 or Ad2 function.
4. Set the output status to Operate.
5. Set the source current of the standard to 273.2
A and 373.2
A, and verify that the measured values
of the 4601 are within the accuracies described in Chapter 9, "SPECIFICATIONS."
The temperature at each current is as follows:
