BEFORE USING THE DEVICE
If there is a difference in the temperature between the storage location and the utilization location,
leave the device for a certain amount of time in the utilization location to perform the average
environmental settings (temperature, humidity).
When the Level Master is turned on, depending on the utilization environment and on the status
of the reference surface measured, the level position may not be always the "0" position
(continuous blue LED). Execute every time the reference settings by means of zero adjustment
in accord with the utilization environment.
③ Push the POWER switch to turn ON the power .
④ Execute the zero adjustment and the levelling checks following
the procedures below.
② Use as reference the line markers on the base of the device and
mark 4 points in the X and Y directions on the reference surface .

① Position the device on the reference surface. When placing the
device, remove oil and dirt from its base and also remove notches,
oil and dirt from the reference surface of the precision plate.
(Example: If the difference in the temperature is 10°C, leave the device for 15-20 minutes.
