7.3 Configuring analog outputs
The device has 2 separate configurable analog recorder outputs, see Connecting the
analogue outputs to the electrical system [
}
35]. The outputs have 16-bit resolution
and deliver a result after every measurement. In the continuous measurement setting,
the renewal rate is 2 Hz. For a higher renewal rate, use the RS-232 interface.
Allocation of functions Using a graphic, you can change the allocation of functions for the outputs.
► In the main menu, select “Settings > Interfaces > analog output”.
To change an allocation:
1. Select the pins with the up and down keys on the left side.
2. Select the desired function with the up and down keys on the right side.
3. Confirm with “OK”.

Function Meaning
Pressure 0 ... 10 V corresponds to 0… 1000 mbar
in linear display
LR mantissa Useful only if the other analog output is
assigned “Leak rate exponent”. The
mantissa corresponds to the output
voltage in volts.
LR exponent Useful only if the other analog output is
assigned “Leak rate mantissa”. The
exponent is calculated from the voltage
as follows: Exponent = (voltage [V] × 2) –
14.
For example:
A voltage of 4.5 V results in an exponent
of (4.5 × 2) – 14 = –5.
A voltage for the mantissa of 3 V is 3.
The leak rate is then: 3 × 10
-5
mbar l/s.
