Facom 709 Bedienungsanleitung Seite 11

Measuring direct or alternating current voltages
Place the contacts in parallel on the circuit to be measured.
The equipment will begin to operate automatically, recognising whether the
current is direct or alternating and choosing the most appropriate of the four
possible settings to measure the tension.
Read the value shown on the display.
The value can be stored by pressing HOLD.

* Operational range: 10 Hz to 400 Hz sinusoidal.
NB: If there is no readout on the display, there is no voltage or the voltage
is lower than 600 mV.
Automatic stop: once disconnected from the circuit, the Multitester 709 will
switch off automatically and the display will go out.
The 709 can detect phase and neutral in an outlet socket:
• Non-earthed socket:
Introduce the red contact into the socket
• if the display lights up, this is phase.
• if the display does not light up, this is neutral.
• Earthed socket:
By attaching the black contact to earth and the red contact to phase or
neutral, the earth/phase or earth/neutral tension can be measured without
causing any break in the differentials
