(1) Confirmation of recording conditions
It is recommended to check to see if the recording indicator shows zero during the night and
gradually goes up and down according as moving the sun during daytime. In addition, it is
desirable to check to see if recording conditions are appropriate and check the number of
recording sheets left.
(2) Confirmation of gauge
It is important to visually check the condition of the gauge during inspection. There are
cases in which scattered objects cover the gauge and the glass part of the sensitive parts are
soiled.
