Always test the NCV function first on a known AC voltage source to avoid incorrect measurements. Incor-
rect measurements may cause an electric shock. The inner conductors are twisted in many cables. For this
reason, move the sensor a few centimetres along the cable to ensure that you cover all parts of the inner
conductors.
10. Additional functions
The multimeter comes with the following additional functions that you can use when taking measurements.
a) Automatic power-off
The multimeter switches off automatically after 15 minutes if no buttons are pressed and the rotary dial is not moved.
This protects the batteries and prolongs the battery life.
The multimeter will beep five times approximately one minute before switching off. Press any button to keep the
multimeter switched on for a further 15 minutes.
If no buttons are pressed, the multimeter will emit a long beep tone and switch off.
If the multimeter switched off automatically, press any button to switch it back on. Alternatively, move the rotary dial
over the "OFF" position. The multimeter will switch back on after 1 - 2 seconds.
The " " symbol indicates that automatic power-off is enabled.
Disabling automatic power-off
When taking prolonged measurements, it is necessary to disable the automatic power-off feature. To disable this
feature, switch off the multimeter.
Hold down the "MODE" button and switch on the DMM using the rotary dial. The multimeter will beep three times and
the automatic power-off symbol will no longer appear on the display.
The multimeter will stay switched on until you switch it off or the batteries are exhausted. Automatic power-off is
automatically re-enabled when you switch off the multimeter.
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 (L) on the side of the multimeter to enable this feature. The multimeter will beep and "HOLD"
will be displayed.
To disable the hold feature, press the "HOLD" button or change the measuring mode.
