Analogue Output Configuration
We always set the meters to suit any requests on your order, so you should not
need to adjust the analogue board. If you didn’t specify ranges, but ordered
option ‘ANI’, the meter will be set for 4-20mA output. If you ordered ‘ANV’ it
will be set for 0-10V.
If you want to change a range, for example from 0-10V to 4-20mA, the zero and
span potentiometers must be adjusted to get best accuracy at 0% and 100%.
You will need to remove the analogue board from the case to change the position
of jumpers and to adjust the fine trim potentiometers. See the page headed “ How
to fit Option Boards” for details of how to expose this board. The analogue
board, if fitted, can be seen plugged into the upper board, and can be easily
identified because it has either 2 or 3 blue potentiometers, depending on version.
You will need to carefully unplug the analogue output board from the upper
board and change the jumper positions to suit your new range, as shown below.
Re assemble the meter, apply power and follow the Analogue Output Settings
procedure on the next page. Measure the analogue output and trim, if needed,
using the ZERO and SPAN potentiometers, for best accuracy.
