General information
5.1 General details on the multimeter
5.1.1
The digital display is a 3 ¾ or 4 ½ digit liquid crystal display with a 13
mm font size and decimal point. The largest display value is 4.000/ 20.000.
5.1.2
The bar graph display comprises 42 segments.
5.1.3
The polarity indication is automatic. Only one polarity with respect to
the socket marked "-" is indicated.
5.1.4
The overranging is indicated by "0L" or "- 0L" and, in part, an acoustic
warning.
Warning, no indication and prior warning in the event of an overload
condition! A exceeding of dangerous contact voltage (> 60 V DC/ 30 V
AC rms) is indicated by an additional flashing symbol "".
5.1.5
The BENNING MM 11 confirms each button press with a signal sound.
Invalid button presses are confirmed by a double signal sound.
In the event of an incorrect circuit of the jack for the mA / A range
the BENNING MM 11 warns with a signal sound and the indication
of in the display .
The acoustic alarm and the indication
if a safety measuring lead is plugged into the jack for the mA or
A range and the corresponding current measurement range was
selected by means of the rotary switch .
The acoustic alarm and the indication
in the case of a defective fuse, if the safety measuring lead is plugged
into the jack for the mA or A-range and the corresponding current
measurement range was selected by means of the rotary switch .
5.1.6
The BENNING MM 11 features individual setting options which in part
remain active even after a shutdown. In order to change a setting,
press one of the following buttons and simultaneously activate the
BENNING MM 11 from its "OFF" switch position.

60 Hz). This adjustment ensures improved stability
and accuracy in AC V mode. These settings are main-
tained even after the BENNING MM 11 is switched off.
The settings are modified only after a new presetting!
