General information

5.1 General details on the multimeter
5.1.1 The digital display  for the test voltage is a 4-digit liquid crystal display
with 16 mm high numerals. The largest numerical value which can be
displayed is 6000.
5.1.2 The polarity indication  is automatic. Only one polarity with respect to
the socket marked "-" is indicated.
5.1.3 The overranging is indicated by "OL" or "-OL" and, in part, an acoustic
warning.
Warning, no indication and prior warning in the event of an overload
condition!
5.1.4 The MIN/MAX button function  inputs and stores automatically the
highest and lowest measured value. The following values are indicated
by button operation:
"MAX" indicates the stored maximum value, and "MIN" indicates the
lowest value. The continuous detection of the MAX-/ MIN value can
be stopped or started by pressing the button "HOLD"  . Pressing the
button "MIN/MAX" for an extended period of time (2 seconds) switches
back into normal mode.
5.1.5 The RS-232 button  activates the optical infrared interface for trans-
mitting the measured values from the BENNING MM 10 to a PC/ lap-
top. The PC/ laptop is galvanically separated from the measuring signal
by means of the optical infrared interface. The activation is effected with
the simultaneous display of "RS232" in the display unit.
5.1.6 The button "RANGE"  is used to index the manual measuring ranges
whilst simultaneously fading out "AUTO" in the display. Press the but-
ton for an extended period (2 seconds) to select the automatic range
selection (indication "AUTO"):
5.1.7 Measured value storage "HOLD": Press the button "HOLD"  to store
the measured result. At the same time, the display shows the symbol
"HOLD. A renewed press of the button switches back into measuring
mode.
5.1.8 Button (yellow)  switches on the display illumination. Press button
again to switch off.
5.1.9 The measuring rate of the BENNING MM 9/ 10 amounts nominally to
1.5 measurements per second for the digital display.
5.1.10 The BENNING MM 9/ 10 is switched on or off by the rotary switch  .
Shutdown position "OFF".
5.1.11 The BENNING MM 9/ 10 switches off automatically after approx. 10
minutes (APO, Auto Power Off). It switches back on again if a button
or the rotary switch is operated. A buzzer sound signals the automatic
shutdown of the unit. The shutdown is not active, if the RS-232 button
is first operated.
5.1.12 Temperature coefficient of the measured value: 0.15 x (stated measur-
ing precision)/ °C < 18 °C or > 28 °C, related to the value for the refer-
ence temperature of 23 °C.
5.1.13 The BENNING MM 9/ 10 is supplied by a fitted 9 V block battery
(IEC 6 LR 61).
5.1.14 If the battery voltage drops below the specified operating voltage of the
BENNING MM 9/ 10, then a battery symbol  appears in the display  .
5.1.15 The life span of a battery amounts to approx. 300 hours (alkali battery).
5.1.16 Appliance dimensions:
(L x W x H) = 158 x 76 x 38 mm without rubber protection frame
(L x W x H) = 164 x 82 x 44 mm with rubber protection frame
Appliance weight:
265 g without rubber protection frame
365 g with rubber protection frame
