Connection:

Via plug-in, lockable screw terminals.

Ambient conditions:

Operating temperature: 0 °C to +40 °C,
relative humidity: 35 %rH to 95 %rH.

Programming:

Programming and operation is menu-driven via the front buttons. It is done via text and can be switched between 5 languages. (English, Italian, German, French, Spanish). All settings are protected by a 4-digit password (cannot be changed). Programming is also possible via the Wachendorff EMG APP (via NFC/RFiD*) for Android smartphones. For programming via APP, the strain gauge display can also be in a de-energized state. The Wachendorff EMG app is currently only suitable for Android operating systems. A Wachendorff EMG app that supports iOs operating systems will follow soon.

*: When interrogated by a reader that supports the NFC-V protocol, the device is to be considered a VICC (Vicinity Inductively Coupled Card) in accordance with the ISO/IEC 15693 standard. The DMS display operates at a frequency of 13.56 MHz. The device itself does not emit any radio waves.

Note on programming:

The NFC sensor is located on the right-hand side of the display, behind the buttons.
Protective covers for smartphones can interfere with the connection and should therefore be removed from the smartphone for the programming period.

Weight:

approx. 165 gram
