412 Ohms Calibration Front Panel

If you do not have the value resistors (290 W, 2.9 kW, 29 kW, etc.) required by the Fluke

45 calibration prompts, the requested value (prompt) must be edited to the value available. (See "Editing the Prompt for Different Calibration Points", later in this chapter.) In the following procedure, the Fluke 5700A Multifunction Calibrator is used as the ohms source, with input values of 190 W, 1.9 kW, 19 kW, 190 kW, and 1.9 MW.

1. If the meter is already in calibration mode, press the (^B or button to select W calibration. Otherwise, select calibration mode first (press Cal Enable button for three seconds), then select W calibration by pressing the ( button six times.

2. Connect the ohms source to the meter in a four-wire configuration. Refer to Figure 41.

3. On the 5700A, select 2-wire compensation ON, with external sense. Then program the 5700A for the output in step 25 of Table 4-5.

4. Edit the meter prompt display to read the same value as the 5700A output display.

5. On the meter, press the (auto) button to calibrate this step. Then continue with steps 26 through 29 in Table 4-5.
