Start-up
Switch on unit by connecting the power supply.
The instrument will automatically execute the following sequence of steps:
The unit will run a check, causing all display segments to light up for 2 seconds.
Both outputs are switched off and the corresponding LED goes dark.
Basic settings are automatically checked for plausibility. If they fail, the
instrument generates an error message (see section 7).
The zero point is then calibrated if this function is part of the instrument’s
program. If zero point lies outside of the permissible range, the instrument
generates an error message (see section 7).
Transition to monitoring and display mode:
Displays current pressure
Reads out an analogue value proportional to the pressure
Controls switching outputs in keeping with set parameters
Displays output states with LED
Setting instrument parameters as detailed in section 6.1.
After its parameters have been set, the instrument is in monitoring and display mode, in
which it can perform its measurement, control and monitoring functions.
