[4] DESCRIPTION OF FUNCTIONS AND TERMS
4-1 Auto Power Off
If no switch or button is operated for about 30 minutes after power
on, the power will automatically be turned off and the display will
become blank.
To reset the meter, press any button or remove the test leads or
the clamp sensor (CT) from an object to measure and set the
function switch to OFF.
*In the auto power off mode, a very small amount of current
keeps flowing. Therefore, when measurement has been
finished, be sure to return the function switch to the OFF
position.
*The auto power off function cannot be canceled.
4-2 AC Detection Method
This meter employs the average value method and therefore
indicates an average value of voltage or current in the positive
half cycle. No error will occur in measurement when the input
waveform is sinusoidal wave with no distortion. However, if the
input waveform is distorted sinusoidal wave or non-sinusoidal
wave, an error of magnitude proportional to waveforms will occur.
[5] MEASURING PROCEDURE
1. Do not apply an input signal exceeding the maximum rated input of
each function.
2. During measurement, do not change the function switch.
3. During measurement, do not hold a place beyond the barrier of the
meter or the test pin side of the flange of the test leads.
4. When measurement has been finished, remove the clamp sensor
(CT) and test leads from the object measured and return the function
switch to the OFF position.
