If the path of the actuator is not from zero to max.
value but, only a apart of it, you may calibrate meter
to correspond the real-path. Indicator saves to its
memory min./max. positions and this does not chan-
ge the scaling of the display. F.ex. display is scaled
0..100% corresponding 0-1000 ohm. In the field,
however,whenthevalveisclosedtherealvalueis70
ohmandwhenclosedtherealvalueis872ohm.This
means that display do not show 0-100% as desired.
This drawback can be easily corrected as follows:
Potentiometer input
Meter accepts pot. input in both channels, each
having its own scaling. Standard ranges are
0..25...1000 ohm. Inside the meter you can change
two resistor for range 10 times, ie. 0..250...10000
ohm.Ifyou usethe expanded rangeyou cannotuse
RTD´s. Standard range allows RTD, or some other
sensor on the other channel. You can set all mathe-
