5.6 Data transmission to PC and smartphone/ tablet
5.6.1
Data transmission to the PC
To transmit measured values, please install the PC software BENNING PC-Win
MM 12 and the hardware driver from the CD-ROM. Then, connect the multimeter to
the PC using a serial data cable with USB connector. For an operating manual of the
PC software, please refer to the “Help” function in the menu bar.
The PC software BENNING PC-Win MM 12 offers the following functions:
-
Graphical representation of the measured values recorded in real time by the
multimeter and storage of these values as MS Excel
®
file. The maximum number
of measured values is limited to 100,000 measured values. The sampling rate
can be adjusted from 1 s to 600 s.
-
Download of the measured values stored in the data logger “LOG” (up to 40,000
measured values) and in the memory “MEM” (up to 1,000 measured values) of
the digital multimeter and storage of these measured values as an MS Excel
®
file.
5.6.2
Data transmission to the smartphone/ tablet
The BENNING MM 12 is provided with a Bluetooth
®
Low Energy 4.0 interface for real-
time wireless transmission of measured values to an Android or IOS device.
The “BENNING MM-CM Link” app required for this is available in the Google Play
Store and in the Apple App Store.
6. Ambient conditions
-
The BENNING MM 12 is designed only for measuring in dry surroundings,
-
Maximum barometric height during measurement: 2222 m.
-
Overvoltage category / setting category: IEC 60664/ IEC 61010-1 → 600 V category IV;
1000 V category III.
-
Degree of contamination: 2
-
Protection class: IP 30 (DIN VDE 0470-1 IEC/ EN 60529).
IP 30 means: Protection against access to dangerous parts and protection against solid
impurities of a diameter > 2.5 mm, (3 - first index). No protection against water, (0 - second
index).
-
Operating temperature and relative humidity:
At operating temperatures of 0 °C to 30 °C: relative humidity under 80 %.
At operating temperatures of 31 °C to 40 °C: relative humidity under 75 %.
At operating temperatures of 41 °C to 50 °C: relative humidity under 45 %.
-
Storage temperature: The BENNING MM 12 can be stored at temperatures from - 20 °C to
+ 60 °C (humidity 0 up to 80 %). The batteries must be removed from the unit.
7. Electrical data
Note: The measurement accuracy is stated as the sum of
-
a relative proportion of the measurement value and
-
a number of digits (i.e. numerical steps of the last place).
This measurement accuracy applies for a temperature of 18 °C to 28 °C and a maximum relative
humidity of max. 80 %.
For the indicating range of 40,000 digits (4¾ digit mode), the specified digit deviation must be
multiplied by 10.
