Calibration of the instrument channels
– Channel x
The
Channel x
sub-list appears after
entering the
Vibration
option in the
Calibration
list. It consists of five
positions, which are used to perform the
calibration
(
System Check
,
Calibr. By Sensitivity
,
Calibr. By Measurement
), or used for
checking the parameters of the previous
calibrations and (
Calibration History
)
and
to delete previous calibration
information
(
Clear Calibr. History
).
<ENT>
Note: The calibration factor is always added to the results in the Level Meter, 1/1 Octave,
1/3 Octave, FFT modes.
Note: The calibration level and the calibration result are expressed in different units depending on
the settings of the instrument. The metric or non-metric Vibration units are set in the Vibration Units
window (path: <Menu> / Auxiliary Setup / Vibration Units). Additionally, the linear or logarithmic units
are set in the Display Scale window (path: <Menu> / Display / Display Scale).
Note: It is not possible to check and calibrate the instrument during the execution of the
measurements. It is possible to open different lists and sub-lists but the positions in these lists are
not displayed inversely and so -
not accessible. The “►” icon indicates that the instrument is in the
measurement process. In order to change the sensitivity, the current measurement in progress must
be finished!

instrumentation. Checking should be carried out immediately before and
after measurements are made.
