Overview
SERIES 2000-RANGE-VALVE
Cancel Mounting Position Effect
All transmitters are calibrated vertically. When a transmitter of the Series 2000-RANGE-VALVE is installed horizontally,
there will be a small “mounting effect” on the zero
(4 mA). For example the transmitter shows 4.03 mA instead of 4.00 mA. This can be easily canceled with P103. In P103
there are three options:
1.
ESC:
Nothing can be changed.
Leave without doing anything. (confirm with PROG).
2.
RESET:
Use this option when you are not sure if P103/SET has been done in a proper way. (confirm with PROG).
when using this option the original factory setting will be valid.
3.
SET:
Canceling mounting position effect. (confirm with PROG).
When “SET” is selected the transmitter is automatically adjusted at 4.00 mA. The span will not be affected.
CAUTION:
Do not apply pressure while executing “cancel mounting position effect”
N.B.:
From revision 2 the description above is valid. Transmitters working with software revision 1 will direct process cancel
mounting position.

Several engineering units can be shown on the display
by using a conversion factor. (See conversion table).
Four engineering units will light up on the display
(mH

O, inH
2
O, bar and PSI).
N.B.:
To show one of the engineering units, P109 must
be adjusted at 1 (= pressure unit).
This will be explained with an example (e.g. bar):
1. Push at [PROG] till “100” is shown on the display.
2. Push 4 times at [
h
], go to [P104].
3. Push at [PROG] to confirm this.
4. Push at [
h
] / [SPAN] and adjust at 3 (= bar).
1 = mH
2
O (=mWC), 3 = bar, 5 = PSI, 11 = inch WC.
5. Confirm with [PROG].
The transmitter will now read out in bars.

the value of the highest range is larger than 9999, “NA” will
appear in the display (Not Applicable). Another unit must be
chosen.
