(5) In case of DC current measurement, output is positive when
the current flows from the upside to the underside of the
clamp adaptor as shown in Fig.2.
5-2-2 AC current measurements (2A, 20A&200A ranges)
Note :
For AC current measurements, input waveform will be
available at the output jack, DC coupled and without
distortion. Therefore, true RMS measurements
would be possible using a true RMS reading AC
Voltmeter. In case of non-sinusoidal input current,
the reading may not be accurate when the 8113 is
connected to an average responding AC voltmeter
calibrated in RMS of a sinewave.
(1) With the power switch set to ON position, select the desired
range.
(2) Refer to Table 3 for output voltage against input current.

Note : Measurements can be made up to 5A at the 2A range
position and up to 50A at the 20A range position.
(3) Press the trigger to open the transformer jaws and clamp
and onto one conductor only. The current measured will be
displayed as voltage. Take the reading in amperes by
referring to Table 2 for voltage/current conversion.
