- Universal measuring input (for standard signals and coope- ration with temperature sensors).
- New range in DC voltage measurement: +/- 75mV.
- Relay alarm output.
- Visualization of the measurement as a horizontal or vertical bar graph - NEW!
- Universal supply voltage from 24 V up to 230 V a.c./d.c.
- Supply of object transducers 24 V d.c.
- OLED display.
- Meter configuration through miniUSB connector with free eCon software.
- Programmable parameters in eCon software: ◦ selection of measured value, ◦ rescaling of indications (individual characteristic), ◦ accuracy of measured value (decimal point), ◦ alarm output mode, ◦ measurement averaging time, ◦ defining your own unit, ◦ language selection.
