ΔREL Function
For an insulation, resistance, or capacitance measurement, you can configure the instrument to
subtract a reference value from the measured value and display the difference.
To activate this function, take a measurement, and then press the
ΔREL
button. This measurement
becomes the reference (Rref) and will be stored and subtracted from subsequent measurement
values (Rmeas).
The
ΔREL
symbol appears on the LCD while this function is activated. If the
measured value is less than the stored value, the display becomes negative.
You can display the difference as a percentage of the reference (
) by pressing the
u
button until the % sign appears:
Note: For insulation measurements, only the digital display is modified by ΔREL. The bar graph
continues to display the true measured value.
To deactivate the
ΔREL
function, press the
ΔREL
button or turn the rotary switch to another setting.
