Digital value
- 4 digital and decimal point
- basic function module: indicates a perma-
nent bar measurement range
- menu-driven module: allows individual
scaling of bar measurement range
Connection is made via a plug connector
according to the "Electrical connection“ sec-
tion.

Adjustment system
• Select the required function with the rotary
switch.
• Change the value with the "+“ and "–“ keys.
• Reset rotary switch to OPERATE, the ad-
justed values are transferred to the EEP-
ROM-memory. They remain there even in
case of voltage drop.
Adjustment
For adjustment of zero and span, an amme-
ter must be connected to terminals 1 and 3.
The measured value is identical to the output
current.
1 Adjustment of zero
(e.g. process pressure zero or vessel
empty)
• Set rotary switch to zero
• By pushing the "+“ and "–“ keys (simulta-
neously) the current jumps directly to 4 mA
or set it to 4 mA by pushing the "+“ and "–“
keys.
Adjustment range of zero:
-20 % … +95 % of the nominal range (corre-
sponds to turn of up to +95 %)
