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
