1. Connect the applicable calibration equipment in Table 10-1;
for example: see Section 3.2.9 (Example procedure:
Measure or simulate an RTD (or Resistance)), example B.
2. Let the equipment get to a stable temperature (minimum: 5
minutes since the last power on).
3. Use the calibration menu (Section 10.3) to do a two-point
calibration for each range.
• Range: 0-400Ω
• Range: 400Ω-2000Ω
• Range: 2kΩ-4kΩ
4. To make sure the calibration is correct, select the applicable
Resistance (source) function; see Section 3.2.9, (B).
5. Set the specified values (Table 10-11). Make sure the error
is in the specified limits.
