10. Additional functions

You can use the function button (C) to enable a range of different functions. The multimeter beeps each time you
press the button.
a) REL function
The REL function allows you to take a reference measurement to avoid possible line losses (e.g. during resistance
measurements). This function resets the current measurement to zero.
To enable this function, press and hold toe "REL" button for approximately one second. "Δ" will appear on the display
and the measurement will be reset to zero.
To disable this function, change the measurement mode or press and hold the "REL" button for approximately one
second.
The REL function is not available in the following modes: Battery test, diode test and continuity
test.
The "REL" button only works when a measured value is displayed. It cannot be used when "OL" is
displayed.
b) HOLD function
This feature freezes the current reading on the display so that you can record it for future reference.
When testing live wires, make sure that this function is disabled before taking any measurements,
otherwise the measurement will be incorrect!
Press the "HOLD" button to enable this feature. The multimeter will beep and "H" will be displayed.
To disable the hold feature, press the "HOLD" button or change the measuring mode.
c) Auto power-off function

power and prolongs the battery life. The
The multimeter will beep several times approximately 1 minute before it turns off. If the REL/HOLD button is pressed
before the multimeter switches off, the multimeter will beep again in 15 minutes. A long beep indicates that the mul-
timeter is switching off.
To switch the DMM back on, move the control dial over the "OFF" position or press the REL/HOLD button.
