Calibrations
IMPORTANT
Periodic calibration is necessary in order to ensure that the
instrument provides correct measurement results of the specified
accuracy.
The calibration frequency varies depending on the status of the
instrument or installation environment. We recommend that the
calibration frequency is determined in accordance with the status of
the instrument or installation environment and that you request that
calibration be performed periodically.

been attached. Make sure that the protector has been removed
and rinse with room-temperature water.
