1. Brief description
The panel meter instrument M2-1F is a 5-digit device for pulse signals, respectivley 2- and 3-wire
sensors. The configuration happens via four keys at the front. The integrated programming interlock
prevents unrequested changes of parameters and can be unlocked again with an individual code.
Optional the following functions are available: a supply for the sensor, a digital input for triggering of
Hold (Tara), one analog output or switching outputs for further evaluating in the unit.
The electrical connection is done via plug-in terminals on the back side.
Selectable functions like e.g. the recall of the min/max-value, an averaging of the measuring signals,
a nominal presetting or setpoint presetting, digital frequency filter for contact bounce suppression
and disturbance suppression with adjustable key relation, a direct threshold value regulation during
operation mode and further measuring setpoints for linearisation, complete the modern device
concept.

4. Function- and operation description
Operation
The operation is divided into three different levels.
Menu level (delivery status)
This level is for the standard settings of the device. Only menu items which are sufficent to set the
device into operation are displayed. To get into the professional level, run through the menu level
and parameterise “prof“ under menu item RUN.
Menu group level (complete function volume)
Suited for complex applications as e.g. linkage of alarms, setpoint treatment, totaliser function etc. In
this level function groups which allow an extended parameterisation of the standard settings are
availabe. To leave the menu group level, run through this level and parameterise „uloc„ under menu
item RUN.
Parameterisation level:
Parameter deposited in the menu item can here be parameterised. Functions, that can be changed
or adjusted, are always signalised by a flashing of the display. Settings that are made in the
parameterisation level are confirmed with [P] and thus safed. By pressing the „zero-key“ it leads to
a break-off of the value input and to a change into the menu level. All adjustments are safed
automatically by the device and changes into operating mode, if no further key operation is done
within the next 10 seconds.

4.1. Parameterisation software PM-TOOL:
Part of the PM-TOOL are the software on CD and an USB-cable with device adapter. The
connection is done via a 4-pole micromatch-plug on the back side of the device, to the PC-side the
connection ist done via an USB plug.
System requirements: PC incl. USB interface
Software: Windows XP, Windows VISTA
With this tool the device configuration can be generated, omitted and safed on the PC. The
parameters can be changed via the easy to handle program surface, whereat the operating mode
and the possible selection options can be preset by the program.

Setting end value of the measuring range, END:
Default: 100e3
Choose between six different frequency ranges. Confirm the selection with [P] and the display
switches back to menu level.
Setting the final value of the measuring range, END:
Default: 10000
Set the final value from the smallest to the highest digit with [▲] [▼] and confirm each digit with
[P]. A minus sign can only be parametrized on the highest value digit. After the last digit, the
display switches back to the menu level. If Sens was selected as input option, you can only
select between noca and cal.With noca, only the previously set display value is taken over, and
with cal, the device takes over both the display value and the analogue input value.
Selection of the input signal, TYPE:
Default: frequ
If the scaling of the device is done via SEnS.F (Sensor calibration), the frequency range needs to
be preset under rAnGE and is adjusted by application of the final value /initial value. If FrEqU
(Factory calibration) is preferred, the final value needs to be entered under End and the final
frequency needs to be entered under EndA. Under OFFS the initial value needs to be entered and
under OFFSA the initial frequency. There is no application of the measuring signal. Confirm the
selection with [P] and the display switches back to menu level.
Parameterisation levelMenu level
5.1. Switching-on
Once the installation is complete, you can start the device by applying the voltage supply. Before,
check once again that all electrical connections are correct.
Starting sequence
For 1 second during the switching-on process, the segment test (8 8 8 8 8) is displayed, followed by
an indication of the software type and, after that, also for 1 second, the software version. After the
starting sequence, the device switches to operation/display mode.

Rescaling the measuring input values, EndA:
Default: 10000
With this function, you can rescale the input value of e.g. 8.000 Hz (works setting) without
applying a measuring signal. If sensor calibration has been selected, these parameters are not
available.
Rescaling the measuring input values, OFFA:
Default: 0
With this function, you can rescale the input value of e.g. 100 Hz (works setting) without
applying a measuring signal. If sensor calibration has been selected, these parameters are not
available.
Setting up the display time, SEC:
Default: 1.0
The display time is set with [▲] [▼]. The display moves up in increments of 0.1 sec up to 1 sec
and in increments of 1.0 sec up to 10.0 sec. Confirm the selection by pressing the [P] button.
The display then switches back to the menu level again.
Setting the decimal point, dot:
Default: 0
The decimal point on the display can be moved with [▲] [▼] and confirmed with [P]. The
display then switches back to the menu level again.
Setting the start/offset value of the measuring range, offs:
Default: 0
Enter the start/offset value from the smallest to the highest digit [▲] [▼] and confirm each digit
with [P]. After the last digit the display switches back to the menu level. If Sens.F was selected
as the input option, you can only select between noca and cal.With noca, only the previously set
display value is taken over, and with cal, the device takes over both the display value and the
analogue input value.

5. Setting up the device
Setting up the final value of the analog output, Out.En:
Default: 10000
The final value is adjusted from the smallest digit to the highest digit with [▲] [▼]and digit by
digit confirmed with [P]. A minus sign can only be parameterised on the highest digit. After the
last digit, the device changes back into menu level.
Setting up the initial value of the analog output, Out.OF:
Default: 00000
The final value is adjusted from the smallest digit to the highest digit with [▲] [▼]and digit by
digit confirmed with [P]. A minus sign can only be parametrised on the highest digit. After the
last digit, the device changes back into menu level.
Selection of analog output, Out.rA:
Default: 4-20
Three output signals are available: 0-10 VDC, 0-20 mA and 4-20 mA, with this function, the
demanded signal is selected.
Adjustment of the optimum digital frequency filter, fi.frq:
Default: NO
If the optional filter is not activated by the adjustment „No“, frequences are ignored by the
adjusted frequency filter. Act on the assumption that the pulse-duty factor is 1:1. Accordingly
the minimal pulse duration is derived from the half of the time of oscillation. Use a filter of 10 Hz
or 20 Hz for contact bounce suppression.
Setting of the pulse delay, dELAY:
Default: 0
With the impulse delay of 0 – 250 s (max), frequencies can be collected, which are even
smaller than by the predetermined measuring time of the device. If e.g. a delay of 250 seconds
is set, this means that the device waits up to 250 seconds for an edge, before it assumes a 0
Hz-frequency. Thus frequencies up to 0.004 Hz can be collected.

Hysteresis for limit values, HY-2:
Default: 00000
The delayed reaction of the alarm is the difference to the threshold value, which is
defined by the hysteresis.
Threshold values / Limits, LI-2:
Default: 3000
This value defines the threshold, that activates/deactivates an alarm.
Function if display falls below / exceeds limit value, FU-1:
Default: high
The limit value undercut can be selected with Louu (LOW = lower limit value) and limit value
exceedance can be selected with high (HIGH = upper limit value). If e.g. limit value 1 is on a
switching threshold of 100 and occupied with function „high“, the alarm will be activated by
reaching the threshold. If the limit value is allocated to „Low“, an alarm will be activated by
undercut of the threshold. See page 29.
Hysteresis for limit values, HY-1:
Default: 00000
For all limit values exists a hysteresis function, that reacts according to the settings (threshold
exceedance / threshold undercut).
Function for threshold value undercut /exceedance, Fu-2:
Default: high
A limit value undercut is selected with Louu (for LOW = lower limit value), a limit value
exceedance with High (for HIGH = higher limit value). If e.g. limit value 1 is on a threshold level
of 100 and allocated with function High, an alarm is activated by reaching of the threshold level.
If the threshold value was allocated to Low, an alarm will be activated by undercutting the
threshold value, as long as the hysteresis is zero.
Threshold values / limit values, LI-1:
Default: 2000
For both limit values, two different values can be parameterized. With this, the parameters for
each limit value are called up one after another.

5.3. Programming interlock „run“
Master code (4-digit number-combination free available), A.CodE:
Default: 1234
With this code, all parameters can be unlocked, if LOC has been activated before under menu
item run. By pushing [P] during operation mode for approx. 3 seconds, Code appears in the
display. The user can now reach all parameters by entering A.codE. Leaving the parametrisation,
under menu item run, the user can unlock them permanently by choosing ULOC or ProF. So,
there is no need for anew code entering, even by pushing [P] during operation mode again.
Activation / deactivation of the programming lock or completion of the standard
parameterization with change into menu group level (complete function range), run:
Default: uloc
With the navigation keys [▲] [▼], you can choose between the deactivated key lock Uloc
(works setting) and the activated key lock Loc, or the menu group level ProF. Confirm the
selection with [P]. After this, the display confirms the settings with "-----", and automatically
switches to operating mode. If Loc was selected, the keyboard is locked. To get back into the
menu level, press [P] for 3 seconds in operating mode. Now enter the CODE (works setting 1 2 3
4) that appears using [▲] [▼] plus [P] to unlock the keyboard. FAIL appears if the input is
wrong.
To parameterise further functions ProF needs to be set. The device confirms this setting with
„-----„and changes automatically in operation mode. By pressing [P] for approx. 3 seconds
in operation mode, the first menu group InP is shown in the display and thus confirms the
change into the extended parameterisation. It stays activated as long as ULOC is entered in
menu group RUN , thus the display is set back in standard parameterisation again.
User code (4-digit number-combination, free available), U.CodE:
Default: 0000
If this code is set (>0000), all parameters are locked, if LOC has been selected before under
menu item run. By pushing [P] during operation mode for approx. 3 seconds, Code appears in
the display. To get to the unlocked reduced parameter, the user needs to enter the preset
U.Code. This code has to be entered before each parametrisation, until the A.Code (Master code)
unlocks all parameters again.

5.4. Extended parametrisation (Professional operation level)
Setting the final value of the measuring range, END:
Default: 10000
Set the final value from the smallest to the largest digit with [▲] [▼] and confirm each digit with
[P]. A minus sign can only be parameterized on the highest value digit. After the last digit, the
display switches back to the menu level. If Sens was selected as input option, you can only
select between noca and cal.With noca, only the previously set display value is taken over, and
with cal, the device takes over both the display value and the analogue input value.
Setting the end value of the measuring range, END:
Default: 100e3
Choose between six different frequency ranges. Confirm the selection with [P] and the display
switches back to menu level.
Selection of the input signal, TYPE:
Default: frequ
If the scaling of the device is done via SEnS.F (Sensor calibration), the frequency range needs to
be preset under rAnGE and is adjusted by application of the final value /initial value. If FrEqU
(Factory calibration) is preferred, the final value needs to be entered under End and the final
frequency needs to be entered under EndA. Under OFFS the initial value needs to be entered and
under OFFSA the initial frequency. There is no application of the measuring signal. Confirm the
selection with [P] and the display switches back to menu level.

Rescaling the measuring input values, OFFA:
Default: 0
With this function, you can rescale the input value of e.g. 100 Hz (works setting) without
applying a measuring signal. If sensor calibration has been selected, these parameters are not
available.
Rescaling the measuring input values, EndA:
Default: 10000
With this function, you can rescale the input value of e.g. 8.000 Hz (works setting) without
applying a measuring signal. If sensor calibration has been selected, these parameters are not
available.
Setting up the display time, SEC:
Default: 1.0
The display time is set with [▲] [▼]. The display moves up in increments of 0.1 sec up to 1 sec
and in increments of 1.0 sec up to 10.0 sec. Confirm the selection by pressing the [P] button.
The display then switches back to the menu level again.
Setting the decimal point, dot:
Default: 0
The decimal point on the display can be moved with [▲] [▼] and confirmed with [P]. The
display then switches back to the menu level again.
Setting the start/offset value of the measuring range, offs:
Default: 0
Enter the start/offset value from the smallest to the highest digit [▲] [▼] and confirm each digit
with [P]. After the last digit the display switches back to the menu level. If Sens.F was selected
as the input option, you can only select between noca and cal.With noca, only the previously set
display value is taken over, and with cal, the device takes over both the display value and the
analogue input value.

5. Setting up the device
Number of additional setpoints, SPCt:
Default: 00
30 additional setpoints can be defined to the initial- and final value, so linear sensor values are
not linearised. Only activated setpoint parameters are displayed.
Setting up the tare/offset value, tArA:
Default: 0
The given value is added to the linerarized value. In this way, the characteristic line can be
shifted by the selected amount.
Adjustment of the pulse-duty factor at activated digital filter, fi.rat:
Default: i-i
Adjustment of the desired pulse-duty factor for pulse duration and pulse interruption. Like this, a
special pulse behaviour can be adjusted.
Adjustment of the optimum digital frequency filter, fi.frq:
Default: NO
If the optional filter is not activated by the adjustment „No“, frequences are ignored by the
adjusted frequency filter. Act on the assumption that the pulse-duty factor is 1:1. Accordingly
the minimal pulse duration is derived from the half of the time of oscillation. Use a filter of 10 Hz
or 20 Hz for contact bounce suppression.
Setting up the pulse delay, dELAY:
Default: 0
With the pulse delay of 0 – 250 s (max), frequencies can be collected, which are even smaller
than by the predetermined measuring time of the device. If e.g. a delay of 250 seconds is set,
this means that the device waits up to 250 seconds for an edge, before it assumes a 0 Hz-
frequency. Thus frequencies up to 0.004 Hz can be collected.

Input variable of process value, SIG.in:
Default: a.meas
This parameter controls the device via the analog input signals a.meas = Sens.f repectively fre9u
or via the digital signals of the interface M.bus = RS232/RS485 (Modbus protocol). Confirm the
selction with [P] and the device changes back into menu level.
Display values for setpoints, dIS.01 … dIS.30:
Under this parameter setpoints are defined according to their value. At the sensor calibration,
like at Final value/Offset, one is asked at the end if a calibration shall be activated.
Analog values for setpoints, InP.01 … InP.30:
These setpoints are displayed at works setting (4-20 mA) only. Here, demanded analog values
can be choosen freely. The input of steadily rising analog values needs to be done self-
contained.
Back to menu group level, rEt:
With [P] the selection is confirmed and the device changes into menu group level „–INP-“.
Display overflow, dI.OUE:
Default: 99999
With this function the display overflow (_ _ _ _ _) can be defined on a definite value.
Display underflow, dI.Und:

Arithmetic, ArItH:
Default: no
With this function the calculated value, not the measuring value, is shown in the display. With
no , no calulation is deposited. With [P] the selection is confirmed and the device changes into
menu level.
Sliding average determination, AVG:
Default: 10
Here, the number of the meterings that need to be averaged is preset. The time of averaging
results of the product of measuring time SEC and the averaged metering AVG. With the selection
of AVG in the menu level DISPL, the result will be shown in the display and evaluated via the
alarms.
Rounding of display values, round:
Default: 00001
This function is for instable display values, where the display value is changed in 1-, 5-, 10- or
50-steps. This does not affect the resolution of the optional outputs. With [P] the selection is
confirmed and the device changes into menu level.
Display time, DISEC:
Default: 01.0

Definite contstant value, const:
Default: 0
The constant value can be evaluated via the alarms or via the analog output, like the current
measurand. The decimal place cannot be changed for this value and is taken over by the
current measurand. Like this a setpoint generator can be realised via the analog output by this
value. Furthermore it can be used for calculating the difference. At this the constant value is
substracted from the current measurand and the difference is evaluated in the alerting or by the
analog output. Thus regulations can be displayed quite easily.
Minimum constant value, con.mi:
Default: -i9999
The minimum constant value is adjusted from the smallest to the highest digit with the
navigation keys [▲] [▼] and confirmed digit per digit with [P]. A minus sign can only be
adjusted on the highest digit. After the last digit the display changes back into menu level.
Maximum constant value, con.ma:
Default: 99999
The maximum constant value is adjusted from the smallest to the highest digit with the
navigation keys [▲] [▼] and confirmed digit per digit with [P]. A minus sign can only be
adjusted on the highest digit. After the last digit the display changes back into menu level.
Zero point slowdown, ZErO:
Default: 00
At the zero point slowdown, a value range around the zero point can be preset, so the display
shows a zero. If e.g. a 10 is set, the display would show a zero in the value range from -10 to
+10; below continue with -11 and beyond with +11.
Dynamic for the sliding average determination, step:
Default: no
With step the sliding average determination can be adjusted dynamically. If 6pro or 12pro is
selected, a frequency value with a variance of 6% or 12% of the current display value is taken
over directly for the sliding averaging. The display appears to be more dynamic at a fast
frequency change, without appearing disturbed by a slightly unsteady frequency.
