12.10 Procedures (CH1): Resistance (Source)
Use this procedure:
1. Connect the applicable calibration equipment. Refer to Table 12-1.
2. Let the equipment get to a stable temperature (minimum: 5 minutes since the last power on).
3. Use the Calibration menu (see Section 12.1) to do a two-point resistance source calibration
for each of the following ranges:
• Range: 0 - 400Ω
• Range: 400Ω - 2000Ω
• Range: 2kΩ - 4kΩ
Figure 12-9: Calibration – Resistance Source CH1 (Range: 2000 to 4000Ω)
4. Do a check that the calibration is correct:
a. Select the Resistance (source) function via the Calibrator Task menu.
b. Use the resistance values in Table 12-13 that are applicable to the calibration.
c. Do a check that the error is in the limit range. Refer to Table 12-13.
