Louis John Fluke Mfg. A low reference supply would also cause period B to lengthen. Carefully inspect the interior of the instru- ment: The AC Converter circuitry creates an offset voltage that, if not compensated for, would create an error in the displayed value of the ac input voltage. The recommended test equipment for troubleshooting is listed in Table Have one to sell?

Refer to the rear panel decal and set the line voltage switch to the local line voltage or V ac. Observe the current digital voltmeter reading and complete the resistor selection procedure given in Tab’e It contributes four ac voltage ranges 2, 20,and V ac and employs a true rms conversion technique to provide true rms measurements with a maximum sensitivity of 10 ;uV.
Connect the input signal or resistance and read the measured value on the display. Clarence House, 31, Clarence St. The digit information is strobed out to the display from pins 34, 33, 32, and 31 of U 1 1one significant digit at a time. The output is positive polarity dc which is calibrated to be equivalent to the rms value of a sinewave. The contents of this section should be read before operating the digital multimeter.
