Instrument’s calibration – Calibration
The instrument channels are factory calibrated with the supplied accelerometer and microphone (optionally) for
the reference environmental conditions (see Appendix C). In case of using other transducers calibration of the
measurement channels should be performed by the user. Periodic calibration of standard transducers is also
required.
The
Calibration
list includes four positions for
calibration each instrument channel separately.
First three channels are dedicated for Vibration
measurements and the fourth channel is
dedicated for Sound measurements.
<ENT>
Note: The Sensitivity parameter in all channels has predefined units and range: 10.0
µV/ms
-2
÷ 10.0
V/ms
-2
for the Channels 1-3 and 50.0
µV/Pa ÷ 50.0 V/Pa
for the Channel 4.
The
Channel x
sub-list consists of three
positions:
By Sensitivity
,
By Measurement
,
which are used to perform the calibration and
Calibration History
used for checking the
results of the previous calibrations.
<ENT>
Note: It is advised to perform calibration of the instrument each time before measurements begin. A
single calibration at the start of each day is usually sufficient for most regulations.
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 list
(path: <Menu> / System / Vibration Units). Additionally, the linear or logarithmic units are set in the
Display Scale list (path: <Menu> / Display / Display Scale).
Note: It is not possible to calibrate the instrument during the execution of measurements. It is possible
to open different lists and sub-
lists but the positions in these lists are not accessible. The “play” icon
indicates that the instrument is in the measurement process.
Note: The recommended factory calibration interval is 12 months for this instrument to be confident
in its continuing accuracy and compliance with the international specifications. Please contact your
local Svantek distributor for further details.
