12.3 REL function
The REL function allows you to take a reference measurement to avoid possible
line losses (e.g. during resistance measurements). For this purpose, the current
indicated value is set to zero. A new reference value is set.
Press the "REL" button to enable this function. The display shows "Δ" and the meas-
urement will be reset to zero. The automatic measurement range selection function
will be disabled.
To disable this function, change the measurement mode or press and hold the but-
ton for approx. 1 second.
The REL function is not available in the "continuity test" mode.
The "REL" button only works when a measurement is displayed. It
cannot be used when "OL" is displayed.
12.4 HOLD function
This function freezes the current reading on the display so that you can record it for
future reference.
When testing live wires, ensure that this function is disabled before
taking any measurements. Otherwise, a false measuring result is
simulated!
Press the "HOLD" button to enable this feature. The multimeter will beep and
"HOLD" will be displayed.
To disable the hold feature, press the "HOLD" button again or change the measure-
ment mode.
12.5 Automatic shut-off function
The multimeter switches off automatically after a preset time if no buttons are
pressed or the control dial is not used. This function saves battery power and ex-
tends the battery life. The time symbol will be displayed at the top left when the
automatic shut-off feature is enabled.
The multimeter will beep one time approx. 1 minute before it turns off. You will hear
a long beep when the multimeter switches off. Pressing any button or moving the
control dial interrupts the shut-off sequence.
