410 DC and AC Milliamp Calibration Front Panel

Perform the dc and ac milliamps calibration as follows:

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

2. Connect the dc milliamps source to the [100 mA] and COM inputs.

3. Apply the dc milliamp outputs indicated in Table 4-5 (steps 18 and 19), and calibrate the meter with the A button.

4. Press the ( button to select mA AC calibration.

5. Connect the ac milliamps source to the [100 mA] and COM inputs.

6. Apply the ac milliamp outputs indicated in Table 4-5 (steps 20 and 21), and calibrating each step by pressing the (auto) button.

Note

Settling times mentioned here assume that steps 1 through 32 are followed in sequence. If you have just calibrated dc volts (steps 1 through 10), but do not follow the subsequent sequence, a special settling period of 4 minutes may be required due to dielectric absorption caused by the 1000 V dc input in step 10. Examples of this requirement include re-checking dc volts calibration (going from step 10 back to step 1) or skipping to ohms calibration (going from step 10 to step 25.)

* A 190 W source calibrates the 300 W range on the Fluke 45 to 0.06%+2 digits +0.02 W. For calibration of

this range to 0.05%+2 digits +0.02 W, use a 290 W source and the procedure detailed under Alternate

Ohms Calibration (Front Panel). This procedure can also be used with appropriate discrete resistor

values (such as a decade box) on all ranges.

** Note that the 300 kW and 3 MW ranges are quite sensitive to noise. Any movement of the input leads or

movement of the hands or body in the vicinity of the leads can cause noisy readings. This causes an

error in the calibration if the (auto) button is pushed during a bad reading. To avoid this, use shielded

leads during this calibration and hold very steady for several seconds with your index finger resting on

the i

button before pressing it. These two cal points should be verified for accuracy at the

conclusion of calibration.
