4.5 functional test
Only open connections in a depressurised state.
Observe the operating parameters in the technical data.
When touching the measuring device, be aware that the surfaces of
the device components could become hot during operation.
4.6 Setting the display
Switch on
After completing the installation, you can put the unit into operation by applying the
supply voltage. Check all electrical connections once again beforehand to ensure that
they are connected correctly.
Start sequence
During the switch-on process, the segment test (8 8 8), the message of the software
type and then the software version are displayed for 1 second for the same time. The
start-up sequence is followed by the change to the operating or display mode.
Parameterisation of 4-digit values
If 4-digit values are to be parameterised, the ones digit is set first and then ([ ]–key
briefly) the tens, hundreds and thousands position is set.
Display of 4-digit values
If, for example, the end value was parameterised to a thousand value during lineari-
sation, the display divides the display by 10 from the display of the thousand value
and displays it as follows: 2‘00 for 2000. The last digit is rounded commercially.

5. Handling and configuration
Description of the operation and setting of the unit with the 3 keys on the display
unit.
5.1 operation
The operation is selectable in 2 presentations: cryptic or numerical (program
numbers). A changeover occurs when leaving the program by selecting „run“, with
subsequent confirmation of „UnL“ for the cryptic menu or „FLt“ for the numeric
menu. Furthermore, the parameter lock can e activated there by selecting „LOC“.
The display has 3 push buttons with which you can parameterize the device and
call stored functions during operation.
Functions, that can be adjusted or changed are always signalled with a flashing
display. The settings made in the parameter level are always confirmed with []
and thus saved. However, the indicator also automatically saves all adjustments
and switches to operating mode if no further keypress occur within 30 seconds. By
simultaneously pressing the two navigation keys [▲] & [▼] the configuration
mode can be interrupted and taring (depending on the selected input) can be
triggered in the operating mode.

Example: Setting of device parameters, e.g. selection of the input signal
Example: Setting of numerical values, e.g. limit value of measuring range
Numerical values are adjusted from the smallest to the largest digit with [▲] [▼] ad
confirmed digit by digit with [ ]. A minus sign can only be parameterized in the most
significant place. After the last digit, the display changes back to the menu level.
Parameterization software PM-TOOL:
Component including the software on CD is a USB cable. The connection is made via
a USB port on the front panel to the PC side.
System requirements: PC with USB-interface
Software: Windows 7, Windows 10
With this tool, the device configuration can be created, skipped and stored on the PC.
The easy-to-use program interface allows the parameters to be changed, whereby
the mode of operation and the possible selection options are preset by the program.
ATTENTION!
When parameterizing with an applied measuring signal, make sure
that the measuring signal has no ground reference to the program-
ming plug.
The programming adapter is galvanically not isolated and directly
connected with the PC. By reversing the polarity of the input signal, a
current can flow through the adapter and destroy the device and
connected components!
