SPECIAL MEASUREMENT FUNCTIONS

Scaled Readings

Except in temperature measure ranges all readings can be presented
in a number of 5 digits and a sign. This number could represent an
engineering unit like gallons/hour, revolutions/minute or any other
relationship. This facility is available on both measurement and
source functions. The original signal reading is still displayed in
smaller sized digits.
Setting-up scaled readings (linear relationship)
Select SCALE to open the set up screen. Fill out the high- and low-
limits for the span (preset at 4 and 20 mA in the milliamp ranges). Fill
out both scale ends for the new scale. Press EXE to show the
working screen.
Note: Scaling in lower ranges only when auto ranging.
Setting-up scaled readings (flow relationship)
Only available on the mA ranges. Select SCALE and FLOW to open
the set-up screen. High- and low-limits for the span are preset at 4
and 20 mA. Change span if necessary. Fill out both scale ends for
the new scale. Press EXE to show the working screen.
Note: Readings are flow related when simulating or reading
dP-transmitters measuring across an orifice plate.
