labelrightarrow Outputs settings →Analogue outputs
Each of the analogue outputs can send a signal in a range between 0-10V. They can be used to control
external devices or record data. The behaviour of the analogue outputs and the type of signal that
will be converted to an analogue value and available at the output, are freely conigured.
The description of analogue output connector pins - see section 2.5.4.
Available coniguration options:
1. SOURCE - source to be converted to an analogue value:
• IG1
• IG2
• IG3
• CH1
• CH2
• CH3
• CH4
2. MODE - selection of conversion method of the measured signal:
• 1 to 1 - the signal is transmitted directly from input to output
• EXPO - the mode used when pressure is the input signal. The output voltage is calcu-
lated using the exponent without taking mantissa into account. From 1E-14, the output
increases by 0.5 V per decade. It is deined by the relation:

𝑒𝑥𝑝𝑜𝑛𝑒𝑛𝑡 + 14

• User Range - deines the measuring range which will be converted into voltage at the
output
3. RANGES - deining the conversion range:
• Min. Range - input signal value, which will correspond to Min. Voltage at the output.
Range means any input signal - e.g. pressure.
• Max. Range - input signal value, which will correspond to Max. Voltage at the output.
Range means any input signal - e.g. pressure.
4. SCALE - selection of measured signal conversion type:
• LINEAR - linear output. It is sometimes useful to retransmit the vacuum over a narrow
range, covering several decades, or other linear signal. In this case, the output voltage is
proportional to the input value. An input signal equal to the Max. Range corresponds
to the upper limit of Max. Voltage, and an input signal equal to the Min. Range corre-
sponds to the lower limit of the output voltage Min. Voltage:
