Calibration
Calibration is recommended in the following cases.
• When the surrounding environment has drastically changed
(example: the product is brought from the inside the room to
the outside)
• When an hour or more has elapsed after measurement is
started or after calibration
1.
Attach the protective cover to the IG-340 main unit.
Be careful not to cause looseness and backlash of the
cover when attaching.

Press and hold the [CAL] button for two seconds.

The IG-340 main unit is adjusted in such a way that the
measurement value obtained when the standard plate has
been measured is set as a standard value (refer to
"Standard value setting" (page 39)).
