Instruction Manual C100
4. Working with the column gauge
4.1 First start-up
Start by fitting the footplate and connecting the accessories ( inductive probes, foot switches,
etc. ). Follow the instructions given in chapter 2 of this manual.
The next step will be programming of the column gauge for your application. Follow the
instructions given in chapter 3 of this manual.
To do this go through all menus listed in these chapter or in the programming card.
After this, use the master and mechanically adjust the probes in the measuring fixture.
Refer to chapter 4.3
Calibrating the Probe inputs -
Refer to chapter 4.6.
Notice : The column gauge is calibrated at the factory for the specified inductive probes.
Recalibration by the user will only be necessary under exceptional circumstances, e.g. when
using uncalibrated probes or extension cables.
The column gauge is now ready for work.
4.2 Measurement operation
- Before starting measuring you should always perform an
Automatic zero adjustment
using the master
supplied in order to compensate all offset errors caused by fluctuations in temperature, wear and so on.
Refer to chapter 4.4.
- Measurements with pneumatic converters ( or in case of special applications ) requiring two masters,
instead of the Automatic zero adjustment an
Automatic gauge calibration
will take place.
Refer to chapter 4.5
The automatic gauge calibration corrects all offset and spread errors.
Switching between the
"Automatic zero adjustment"
and the
"Automatic gauge calibration"
is done
in the Setup menu
"AutoCA".
4.3 Mechanical adjustment of inductive probes
Inductive probes reach their greatest accuracy only within a comparatively small measurement
range. It is therefore extremely important to adjust them very carefully.
1. Connect only one inductive probe at a time.
2. The column gauge must be in Measuring mode. If not, press the
PRG/CAL
key
to leave the
Programming mode.
3. Press the
Ï
and
Ð
keys for more than 3 seconds until the luminous displays
Gauge 1
,
Gauge 2
,
Gauge 3
, and
Gauge 4
start flashing and confirm the Adjustment mode. When this mode is active
the column gauge switches all factors and offsets automatically off and displays the true inductive
probe value.
If
"SECUrE"
appears in the numeric display the keypad is locked. Refer to Setup menu "Automatic
adjustment" (
"0-triG."
→
Adb.
on/oFF set to
"on"
).
4. The column display automatically switches to the column range ±150 µm / 15 Thou and sets two
tolerance marks at ± 50 µm / ± 6 Thou.
5. Adjust now the inductive probe placed on the master to its mechanical zero point. If the measured
values shows on the column display in the green area ( ± 50µm / ± 6 Thou ), the adjustment of the
inductive probe is, adequately set.
6. Disconnect the probe and connect the next probe to be adjusted.
7. When all probes have been adjusted, press the
ENTER
key to exit the Adjustment mode. The
message
Load
appears in the numeric display and all coefficients of the inputs are loaded once
again. The offset values cannot be retrieved. It is therefore necessary to perform an Automatic zero
adjustment or a Gauge calibration before starting work. ( See chapter 4.4 or 4.5 ).
