5. EXAMPLE
A flowmeter produces 20.538 pulses per litre and has a maximum output
frequency on 200Hz. It is required to display the flow rate in litres/min with 1
decimal point and the total in litres with no decimals. A 4-20mA output is
installed and 4mA is to represent 0 litres/m and 20mA is to represent 500 litres/m.
The instrument is then programmed as follows:
Calibration mode is entered by removing the lower cover strip (ie. the dark grey
strip along the bottom of the enclosure) and replacing it the wrong side up.
The following values are then entered:
