・Use a plate with good surface flatness to be sure to obtain a level within 0.01.
・Since the diameter of the LEVEL MASTER WIRELESS is φ109mm, if only 2μof dirt get caught by the
device, a distortion of 0.018mm for 1m will be generated.
・This device (Body/Receiver)is a precision instrument. Do not drop it or cause shocks to it. Also, after the
use, always apply antirust oil to its base and store it using the exclusive storage case.
・When storing the device(Body/Receiver), store it in an environment with a temperature between 0℃and
40℃.
・Since the device is a precision instrument, do not apply coolant to it. Also, after the use, do not leave it on
the machine table, plate or installation jig.
・Since the device(Body/Receiver)is a precision instrument, do not disassemble or modify the device.
Otherwise, its efficiency or lifespan may worsen and the warranty annulled.
・Remove the batteries if the device is not used for a long period.
・If accuracy problems or malfunctions occur, stop using the device and send it to using our
distributors for inspections and repairs.

4-2．How to execute the zero adjustment
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Wireless(Body/Receiver) 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.
③Push the POWER switch to turn ON the power.(Body/Receiver)
④Execute the zero adjustment and the levelling checks following
the procedures below.
②Use as reference the line markers on the base of the Body and
mark 4 points in the X and Y directions on the reference surface.

0.1mm/1m in case of the LOW mode.
The inclination is between 0.08mm/1m and
0.01mm/1m in case of the HIGH mode.
⑳Buzzer sound
Outlet of buzzer sound.
⑱LED level indicator (Central position)
The LED (blue) turns on when the level status
reaches the central position.
The inclination is 0.1mm/1m or less in case of the
LOW mode.
The inclination is 0.01mm/1m or less in case of the
HIGH mode.
⑲Receiver case
21 Batteries box
It is the location where the batteries are installed
(LR03: AAA x4).
・Use a plate with good surface flatness to be sure to obtain a level within 0.01.
・Since the diameter of the LEVEL MASTER WIRELESS is φ109mm, if only 2μof dirt get caught by the
device, a distortion of 0.018mm for 1m will be generated.
・This device (Body/Receiver)is a precision instrument. Do not drop it or cause shocks to it. Also, after the
use, always apply antirust oil to its base and store it using the exclusive storage case.
・When storing the device(Body/Receiver), store it in an environment with a temperature between 0℃and
40℃.
・Since the device is a precision instrument, do not apply coolant to it. Also, after the use, do not leave it on
the machine table, plate or installation jig.
・Since the device(Body/Receiver)is a precision instrument, do not disassemble or modify the device.
Otherwise, its efficiency or lifespan may worsen and the warranty annulled.
・Remove the batteries if the device is not used for a long period.
・If accuracy problems or malfunctions occur, stop using the device and send it to using our
distributors for inspections and repairs.
