3. Programming the column gauge
All programming and settings of the column gauge are done with the 4 keys on the front panel. The user
is taken step by step through the different menus with the help of the lamps and the numeric display. The
programming follows a logic structure and becomes self-explanatory after a short study.
3.1 Key functions
PRG/CAL When this key is pressed the gauge changes from Measuring to Programming mode or
vice versa.
ENTER On Measuring mode ( manual gauge selection mode ) with the ENTER key you switch
to the next gauge.
In Programming mode this key confirms the programmed values and selections.
ÏWhen this key is pressed in Measuring mode the measured value on the numeric
display is increased. A short pressure increments by 1. If the key is held down the
measured value is increased rapidly ( manual zero adjustment ).
In Programming mode the key is used to increase a given value or switch to the next
menu or function.
ÐWhen this key is pressed in Measuring mode the measured value on the numeric
display is reduced. A short pressure decrements by 1. If the key is held down the
measured value is rapidly reduced ( manual zero adjustment ).
In Programming mode the key is used to reduce a given value or to switch to the next
menu or function.
Ï& ÐWhen the Ïand Ð- keys are pressed simultaneously in Measuring mode either an
automatic zero adjustment or a gauge calibration is done.
If the Ïand Ðkeys are pressed simultaneously for more than 3 seconds the internal
zero adjustment offset value is erased and the mode for the mechanical adjustment of
inductive probes is started.
Refer to chapter 4.3 "Mechanical adjustment of inductive probes".
3.2 Foot switch functions
1. On manual gauge selection you switch to the next gauge
2. Output of measured value at RS232 output

Instruction Manual C100
After pressing the ENTER key ( confirm flashing "Unit" ) in the 2nd menu you can select either „mm“ or
„INCH" by pressing the Ïor Ðkey. Confirm with the ENTER key.
Press the Ðkey to advance to the next menu.
Notice : a) If you change the unit, numeric values introduced in the programme, e.g. master values,
nominal size values and tolerances do not change automatically.
b) Further units on request.
The programming of a master value is base of the Automatic Zero Adjustment.
On Automatic zero adjustment ( do this by placing the master piece into the measuring fixture and press
the
Ï and Ð keys simultaneously during Measuring mode ) the master value will be taken as the
measured value and appears on the numeric display.
When measuring comparative values ( shows the deviation to the nominal size on numeric and column
displays ) zero is programmed as master value.
When pneumatic converters are used, Automatic Gauge Calibration can be considered as an option. If
this option is chosen in the Setup menu "AutoCA" you will be prompted to program a second master
value.
If you then enter the same value for both masters, the error message 'Err. 11' will appear. If you enter a
difference between the two masters with more than 3 mm the error message 'Err 12' will appear.
Notice : On Auto Zero Adjustment the zero position of the column gauge related to the master is
automatically adjusted by an offset value.
On Automatic gauge calibration the offset value ( zero point ) and the gain ( pneumatic
spread ) is calculated automatically by the column gauge.

15
Instruction Manual C100
The nominal value indicates the value to be chosen as zero point of the column display. If the nominal
value is 20 mm ( SEt.Pnt. is set to 20 mm ) the column display will show a deviation of 0,1 mm for a work
piece measuring of 20,1 mm.
Notice : The nominal value is used only for the zero position of the column display and does not
influence the numeric display.
In this menu you can set a maximum of 4 tolerance points representing relative deviation from the
nominal value.
Programming starts by selecting one of the four tolerance marks on the column display :
+ red upper tolerance ( red )
+ yellow upper tolerance ( yellow )
– yellow lower tolerance ( yellow )
– red lower tolerance ( red )
The chosen tolerance point flashes. Go to the next point using the Ïand Ðkeys and confirm with
ENTER key. After this you can switch the tolerance point on or off by selecting on / oFF on the numeric
display. You can set the relative deviation from the nominal value ( max. ± 1.5 mm ), if the tolerance point
is switched on.
