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.
Initializing of settings and upgrading to the latest software version may be carried
out during repair and restoration. Please backup any important data before sending
it for repair and calibration.
For LR8514
Only the Humidity Sensor, which affects the measurement accuracy, is subject
to calibration. No calibration for LR8514 Wireless Humidity Logger is required
because it has no measurement circuit that affects the accuracy.
If the instrument is not to be used for an extended period of time
CAUTION
To avoid corrosion from battery leakage and/or damage to the instrument,
remove the batteries from the instrument if it is to be kept in storage for an
extended period.
