Overview
5. Function of Push Buttons
The Series 2000 can be programmed easily by use of the 3 front panel
pushbuttons (See picture right). The display can show engineering units of:
mH
2
O, inH
2
O, bar and PSI.
The functions of the three pushbuttons will be explained below.
This button has 2 functions:
1. It can be directly used for adjusting the zero (zero / 4mA), with or without a test pressure.
When the zero (4 mA) must be adjusted at 0 (atmospheric pressure), the button must be held
until the word “ZERO” appears on the display. The transmitter is now set to 4 mA.
2. Secondly, this button must be used for stepping down in the programming menu or to
decrease a value (-).
Note: For canceling the mounting position effect you have to use P103.
This button has 2 functions:
1. It can be directly used for adjusting the span (20 mA), when using a test pressure (air). When
a test pressure (e.g. 2 bar) is supplied to the transmitter, the button must be held until the
word “SPAN” appears on the display. The transmitter is now adjusted at 20 mA. The span can
also be adjusted without test pressure (see P102).
2. Secondly, this button must be used for stepping up in the programming or to increase
a value (+).
This button has 2 functions:
1. It is used to adjust the 14 Programming Points (P101 to P114). Push it once and P100 is
displayed, use the
h
(SPAN) to step to P101 etc.
2. This button must also be used for confirming the adjustments (enter).
For example if you want to change the adjustment in bars (P104), the following steps
must be taken:
1. Push on [PROG] until “100” appears on the display.
2. Push on [SPAN] 4 times to go to point “P104” (adjustment pressure unit).
3. Push [PROG] to confirm this.
4. Push several times on the
h
(SPAN) to reach 3 (= bar). See also the conversion table (page 12).
1 = mWC, 3 = bar, 5 = PSI, 11 = inch WC
5. Confirm this by pushing once at [PROG].
The transmitter is now adjusted to read in “bar”.
