SIMULATION
CURRENT
In this function, the output current can be simulated to correspond to 0%, 50%
or 100% of the set current range. The ‘error values’ 2 mA (for 4...20 mA) and
25 mA (maximum possible value) or 22 mA for NAMUR can also be simulated.
After activating the simulation mode, the message “S: CURRENT OUTP. SIMUL.
ACTIVE” appears on the display in the HOME position.
Application example:
– checking instruments connected
– checking the adjustment of the internal current signal
Note!
• No simulation is possible if “Positive zero return” is activated.
• The selected simulation mode affects only the current output. The flowmeter
remains fully operational for measurement, i.e. totalizer, flow display etc. are
operating normally.
• Positive zero return interrupts any simulation being carried out and sets
the output current to 0 mA or 4 mA.

CURRENT
In this function, the current and calculated target value of the output current is
shown (0.00...25.00 mA). The effective current can vary slightly due to external
effects such as temperature.
