4.6.4 Calibration
The instrument is factory calibrated for the specified range, but due to
long term drift of components, re-calibration may be necessary in some
cases. For calibrating the instrument a reliable source is required. This
source should be at least ten times accurate compared to the range of
the instrument.
Note: Masibus can provide a calibration service that is traceable to
international standards.
We recommend that you return the instrument to the manufacturer or an
approved service agent for calibration. If you use an alternative
calibration facility, make sure that it uses these standards.
The unit can be calibrated without opening it and without trim pots. To
enter in calibration mode follow the steps below.
First press the MENU/ENT key in RUN mode to enter in Menu page. In
Menu page select the Settings option and press F1 key to enter into the
Setting mode. In setting mode select the Calibration option and press F1
key to enter into the calibration mode.
To calibrate the instrument first enter the correct password. If the
entered password is correct Measure & Source Calibration option will be
enabled.
