With the rotating switch , select the desired function (Ω/ buzzer and diode
symbol) on the BENNING MM 7.
-
Using the blue button on the BENNING MM 7, switch to continuity test
(press button once)
-
Connect the black safety test lead to the COM socket on the
BENNING MM 7.
-
Connect the red safety test lead to the socket for V, Ω, Hz, ºC, ºF,
the BENNING MM 7.
-
Contact the measuring points with the safety test leads. If the measuring
lead resistance between the COM socket and the socket for V, Ω, Hz,
ºC, ºF,
on the BENNING MM 7 is lower than 30 Ω the built-in buzzer is
activated.

9. Maintenance
Before opening the BENNINGMM7, ensure that it is not
connectedtoa s ourceofvoltage!Electricalhazard!
Any work required on the BENNING MM 7 when it is under voltage must
be done only by a qualified electrician. Special steps must be taken to
prevent accidents. Before opening the BENNING MM 7, remove it from all
sources of voltage as follows:
-
First remove both safety test leads from the measurement points.
-
Remove both safety test leads from the BENNING MM 7
-
Turn the rotating switch to "OFF".
