Relative Value Measurement

Except for frequency/duty ratio and diode measurements, all other measurements can employ relative measurement. Press REL
key to enter relative measurement and the meter will record the initial value when pressing the key. And the later displayed
value is:
Displayed value = present measurement value — Initial value
Press REL again to exit relative measurement. Changes of measurement value may be found in relative measurement which
also can be used for the small resistance and the small capacitance measurements, for example, when performing resistance
measurement, connect the red testing line and the black testing line in short, press the REL key to record the values of
resistance (resistance of both the red and black lines), and after that performing resistance measurement again the lead
resistance will have been taken off from the displayed value. When performing capacitance measurement, open the red and
black testing line, press REL key to record the distributed capacitance, and after that performing capacitance measurement
again, the distributed capacitance will have been taken off from the displayed value. During relative measurement, analog bar is
always indicating the present measurement value but not the relative value. When measurement over, OL will display instead of
showing the relative value.
Maximum Value/Minimum Value Measurement
Except for frequency and diode measurements, by pressing the MAX/MIN key the meter will enter the maximum value and
minimum value record state and display the maximum value. The meter measures the present value and continuously judges if
it is necessary to update the maximum or minimum value. Pressing the MAX/MIN key again it is possible to select displaying
