1 Introduction
The PM110 is a digital manometer featuring a Min/Max display
function. Full scale (FS) accuracy is ± 0.5% based on the upper
limit of the measurement range.
Dynamic pressure peaks are measured at a scanning rate of
10ms (100 measurement values/second). The MIN/Max memory
is continuously updated and rewritten.
1.1 Notes on safety / product selection
The correct functioning of the PM110 can only be guaranteed
when the specifications detailed in these operation instructions
are adhered to. In particular, specifications relating to the
permitted upper limit of the measurement range as well as the
permissible temperature range must be observed.
Serious malfunctions leading to personal injury or
damage to property can result from using the chosen
product in applications that do not comply with the
specifications or from disregarding the operating
instructions. In particular, incorrect mounting of the
manometer and the corresponding adapter can cause
the manometer to be torn out of the assembly.
For repairs or calibration of the measurement instruments,
please contact a Webtec sales branch.

A pressure peak is indicated by means of a
pixel (graduation mark).
The indicated value is refreshed at intervals of
50 ms (20 measurements/s).
ACT Indicates the actual pressure.
The indicated value is refreshed at intervals of
300 ms (3 times/s).
MIN/MAX Indicates the MIN, MAX or FS value according
to setting.
The indicated value is refreshed at intervals of
300 ms (3 times/s).

5.1 Turning on (ON)
A self-test procedure is carried
out
The measuring range is indicated
(FS)
Unit (bar) SR- PM-110-MT-XXX
Unit ( SI) SR- PM-110-UN-XXXX
Auto Power Off function is active.
Power off activates automatically
after 5 minutes. This function can
be altered in MENU.
Display mode:
ACT value displayed

5.2 Turn off (OFF)
Press once (briefly) .
5.3 Turn on backlight
Press for 2 seconds.
The backlight goes out automatically after 20 seconds.
5.4 MIN/MAX indication
Use this key to toggle the required value.
The key function is sequential; the values are indicated in the
display in sequence.
The MIN/MAX function is used to measure pressure peaks. The
respective lowest (MIN) and highest (MAX) measured values are
stored in the MIN/MAX memory. Values in the MIN/MAX memory
are erased when the device is turned off. If different pressure
tests are to be carried out in succession, the MIN/MAX memory
must be erased after each measurement.
MIN/MAX/FS value is indicated in the display.
14

5.5 FS Full Scale display
Displaying the upper limit of the scale (FS) is designed to
increase readability of the bar graph function.
The upper limit of the measurement range is indicated
numerically.
FS is indicated in sequence after MIN and MAX.
FS is displayed.
5.6 Erasing the MIN/MAX values
Erases MIN/MAX values.
5.7 OFL Display
This indicates that the applied pressure is
outside given full scale range.
If the message remains displayed when the
PM110 is disconected from the pressure
source, please consult a Webtec Sales Office.
5.8 Zero point correction (ZERO)
The zero point can be corrected manually should undesired
deviations occur when no system pressure is being applied
(atmospheric pressure).
ENGLISH

Caution!
The zero point correction sets the current ACT value to
zero. In order exclude erroneous measurements, ensure
no system pressure is being applied when carrying out
this function.
This initiates the zero point correction. The ACT (actual)
value is indicated in the display as 0.0 bar. The
correction remains active until the device is turned off.
OFL/ZEro is displayed for 3
seconds if the measured pressure
(0 bar) is greater than 5% of the
measurement range.
Zero point correction cannot be
carried out. Please ensure that no
system pressure is being applied.

5.9 Resetting the zero point correction
Turn off the device. Zero point correction is no longer
active when the device is turned off and on again.
5.10 Automatic power off
Press for 2 seconds.
Depending on the device configuration, two different displays
are possible:
