range and 133.3 V for the 0 – 200 V-range.
10.7 Resetting to preset
(standardized) calibration
values
Instead of regular calibration a resetting function can
be activated that will set the calibration values to a
set of preset and standardized values. This will give an
accuracy of about 1%. Resetting can never replace a
regular calibration where accurate and traceable refer-
ence instrument are used, but is a quick and simple
method of solving the problem of having no calibra-
tion values at all. Resetting must always be followed
by a calibration of the zero-offset, which is a part of
the regular calibration procedure.
It is possible to combine resetting and calibration;
first perform a reset and then calibrate the ranges for
which required instruments and sources are available.
The ranges that can not be calibrated will then use
the standard calibration values.
Note: When a reset is performed, ALL settings, values
and parameters will be set to preset default
values. This also implies the settings stored
in INGVAR’s memories, which will be lost if a
reset is performed.
