Overview of Set-up Parameters
When the instrument is turned on, it briefly displays the
software version number, and then switches automatical-
ly to normal operating mode. Pressing
û
causes the set-
up menu to be called up, indicated by
Esc
on the digital
display. After that, by pressing
þ
repeatedly, each of the
set-up parameters is called up in sequence:
Note: Depending on the version of
the instrument that was ordered,
some of the individual parameters
might not be available.
PAS
Password input (appears only if password va-
lue is not zero). Values: 001 to 999
DSP
Selection of unit of measurement.
DAM
Damping (time constant). Range of values
= 0.0 to 100.0 secs
D0
Damping (display only), range of values 0..100.
Additional: -1 = no digital value and -2 = display
turned off completely.
R1A
Switching output 1: turn-off point.
R1E
Switching output 1: turn-on point.
R1D
Switching output 1: delay. Range of values =
0.0 to 100.0 secs. This value applies equally for
turn-on and turn-off delays.
R1F
Switching output 1 action. If
R1F
= 1, acts as
NO contacts. If
R1F
= 2, acts as NC contacts.
R2A
Switching output 2: turn-off point.
R2E
Switching output 2: turn-on point.
R2D
Switching output 2: delay. Range of values =
0.0 to 100.0 sec. This value applies equally for
turn-on and turn-off delays.
R2F
Switching output 2 action. If
R1F
= 1, acts as
NO contacts. If
R1F
= 2, acts as NC contacts.
EIN
Unit of measurement. The selection is indica-
ted by the backlit symbol to the right of the digi-
tal display. A particular unit can be selected on-
ly if it can be meaningfully represented within
the basic measuring range of the instrument.
MA
Measuring range start point. The value of the
measured variable corresponding with the mi-
nimum value of the output signal (0 V, 0 mA or
4 mA, depending on the instrument version).
ME
Measuring range end point. The value of the
measured variable corresponding with the ma-
ximum value of the output signal (10 V or
20 mA, depending on the instrument version).
dPF
Position of decimal place for free unit.
MAF
Measuring range start point (displayed value)
for free unit.
MEF
Measuring range end point (displayed value)
for free unit.
NP
Zero stabilization. Range = 0 to 100 counts.
The value spans symmetrically around the ac-
tual zero point.
OF1
Zero offset correction, input 1. Range = -100 to
+100 counts.
F
Signal conversion function. (0 = linear,
1 = square root,
2 = horizontal cylindrical tank,
3..30 = look-up table)
lIn
Look-up table entry (sub-menu)
oG1
Output signal limiting, minimum
OG2
Output signal limiting, maximum
OEr
Fault signaling (output signal value on detec-
tion of instrument fault).
res
Reset all values to default. (Default values can
be defined only by using the PC interface.)
-P-
Password setting. Permissible password valu-
es = 001 to 999. "000" disables password pro-
tection.
If the password is lost, the instru-
ment can be unlocked only through
a serial interfaced PC, or the instru-
ment has to be sent to the manufac-
turer for this purpose.
If
oG1
and
oG2
are both set to "0", the
output signal will not be subjected to li-
miting.
If
oG1
is set at the maximum value
(11 V or 21 mA), the output signal can
be adjusted using
oG2
to any arbitrary
value between zero and maximum va-
lue, irrespective of pressure measure-
ment. This feature enables the instrument to be used as
a simulated signal source to test signal lines and other in-
struments or systems.
