ALIBRATION
A reserved memory space incorporated in the +CLINO PLUS+ contains calibration data in predefined intervals.
Prior to all displays this data is accessed applying a specialized interpolation and is used to compute the
measurement value. Calibration data stored in this memory is initiated from an automatic calibration process
based on a high accuracy dividing head, which is performed at the manufacturing stage.
Recalibration is possible at any time if suitable and accurate equipment which allows precise setting of angles
(dividing head, sine equipment etc.) is available.
A
recalibration
may also be performed at any time starting the calibration program by key operation. The
following example is for a +CLINO PLUS+ with a measuring range of ± 45 deg. Basically the same procedure is
used for other ranges.
**1**
Mount the +CLINO PLUS+ to the angular reference equipment and set an angle of 50 deg. sloping to the
right (display facing you and data connector being on the right side). Connect the cable of the remote
push button to the data connector.
**2**
Before starting the calibration procedure preferably a reset is performed (See chapter 2.11)
To reset, simultaneously press the two keys
“ON/MODE" and
“ENTER/HOLD" by starting with
the
“ON/MODE" key, for a min. period of 1 sec.
Start the calibration program by pressing first the key
“SELECT/PRINT” and keep pressed while using
simultaneously the key
“ENTER/HOLD” for a period of min. 5 seconds . A successful start to the
calibration program
is indicated by the display showing at first "
00.00" thereafter displaying
in flashing mode which represents the first calibration point.
**3**
To enter a calibration point first confirm that the reference setting corresponds with the value displayed,
then press the remote button or if absent the key
“ENTER/HOLD”. Allow a moment ( a few seconds)
for the +CLINO PLUS+ to register the respective data. The instrument must remain untouched.
**4**
When the calibration data for one setting is successfully stored, the +CLINO PLUS+ will display the next
setting required. The display will, in 5 deg. steps successively show
to
Due to automatic adjustment of acceptance requirement calibration may be impossible if vibrations are
present or if an unstable set-up is used.
**5**
Adjust the angular equipment according to the new value flashing on the +CLINO PLUS+ display.
**6**
Repeat operation 3 to 5 until the last value
is registered.
**7**
Upon completion the +CLINO PLUS+ automatically returns to the mode last set or, if the setting data was
cancelled to the standard setting.
IMPORTANT! Prior to absolute measurements it is necessary to reset zero.
