• Display scaling (calibration)

General

To set the display scaling you select the decimal point link position and

adjust the ZERO (Z) and SPAN (S) control to give the required units.

he ZERO adjusts the ‘zero’ point reading (adjustment range ±1200

counts). The SPAN adjusts the ‘full scale’ reading (adjustment range 20

to 2100 counts).

Procedure

. If the decimal point needs to be changed, remove the back plate by

gently prising apart the four clips that hold it in place, place the link

(on the display board) as shown (to right) and reassemble.

Inject a ‘zero’ (normally 4 mA) signal and adjust the Z control to give

the required display value.

. Set the input source to ‘full scale’ (normally 20 mA) and adjust the S

control to give the required full scale display.

. Recheck the zero and repeat steps 2 & 3 if required.
