of the ambient temperature of ± 2 °C, the measuring accuracy data will apply after 1 hour.
8. Measuring with the BENNING MM 12
8.1 Preparation for measuring
Store and use the BENNING MM 12 only under the correct temperature conditions stated.
Always avoid longer exposure to sunlight.
-
Check the rated voltage and rated current stated on the safety measuring leads. The safety
measuring leads supplied with the unit are suitable for the rated voltage and current of the
BENNING MM 12.
-
Check the insulation of the safety measuring leads. If the insulation is damaged in any way,
do not use the leads.
-
Check the continuity of the safety measuring leads. If the conductor in the safety measuring
lead is interrupted, do not use the leads.
-
Before selecting another function with the rotating switch
J
, always disconnect the safety
measuring leads from the measuring point.
-
Sources of strong current in the vicinity of the BENNING MM 12 may cause unstable or
incorrect readings.
8.2 Voltage and current measurement
Always observe the maximum voltage to earth potential!
Electrical hazard!
The maximum voltage which may be applied to the sockets,
-
COM socket
L
-
socket for
V, Ω,
, Hz,
K
-
socket for mA range
M
and the
-
socket for 10 A range
N
of the BENNING MM 12 to earth is 600 V CAT IV/ 1000 V CAT III.
8.2.1
Voltage measurement
-
Use the rotating switch
J
to select the required function (V AC, mV AC, V DC, mV DC) on
the BENNING MM 12.
- In the direct voltage (DC) range, press the
Function
key
5
(down/ ▼) of the
BENNING MM 12 to select the voltage type to be measured: (DC) or (AC+DC).
-
Connect the black safety measuring lead to the COM socket
L
on the BENNING MM 12.
-
Connect the red safety measuring lead to the socket
K
on the BENNING MM 12.
-
Connect the safety measuring leads to the measuring points. Read the measurement value
displayed in the digital display
1
of the BENNING MM 12.
See figure 2:
Direct voltage measurement
See figure 3:
Alternating voltage measurement
8.2.2
Current measurement
-
Use the rotating switch
J
to select the required range and function (A AC, A DC, A AC/ DC)
on the BENNING MM 12.
-
Press the
Function
key
5
(down/ ▼) of the BENNING MM 12 to select the current type to
be measured: alternating current (AC), direct current (DC) or (AC+DC).
-
Connect the black safety measuring lead to the COM socket
L
on the BENNING MM 12.
-
Connect the red safety measuring lead to the socket for the mA range
M
for currents up
to 400 mA or to the socket for 10 A range
N
for currents greater 400 mA to 10 A on the
BENNING MM 12.
-
Connect the safety measuring leads to the measuring points. Read the measurement value
displayed in the digital display
1
of the BENNING MM 12.
