4.4 Zeroing key
The effects of temperature and positioning of the measurement capsule may cause
the zero-point to shift, thereby distorting the measurement result, i.e., causing the
instrument to display a measured value even when it is not connected to a source of
pressure. Users can recalibrate the zero point by briefly pressing the key.
It is important that no external pressure is applied to the measuring device at the time
of zeroing.
4.5 Analogue output
The EMA 200 has a 0...2V analogue output, allowing it to read out an output voltage
proportional to the pressure. When configuring the instrument, users may set the
pressure at which the instrument will read out an output voltage of 2.0V. The output
voltage is read out of the instrument via a 3.5 mm jack.
