Step 3: Press to activate the control, then or
to adjust the selected place value and or to
select another v alue.
Step 4:

cannot be changed.)
Press when the adjustment is complete.
3.3 Instrument Calibration
Before measuring thickness with the CL 5, the instru-
ment and connected probe must be calibrated. It’s
important that the setup file corresponding to the
attached probe be selected prior to launching the
calibration process.
Calibration requires the use of one or more standards
of known thickness. When a contact probe is installed,
either a one or two point calibration can be specified.
Note that contact probe types require zeroing and the
zeroing process is automatically accomplished as
part of calibration. To calibrate the instrument, follow
the instructions in Figure 3-4 and on your instrument’s
display screen.

Note:
Proper calibration affects the accurate operation of
the instrument. The instrument should be calibra-
ted if there is a change in the type or temperature
of the material being tested, if the attached probe is
changed, after performing any parameter adjust-
ment, or at intervals specified in your test procedures.
3.4 Setting the Maximum and
Minimum Alarms
The CL 5 is equipped with a red LED (at the bottom
center of the instrument’s key pad) that illuminates
whenever the user-inputted minimum or maximum
