Congratulations on your choice of this Magnetic Digital Level. We
suggest you read this instruction manual thoroughly before using the
instrument. Save this instruction manual for future use.
There are four key pads on this instrument, they are (from left
to right): calibration/sound key, mode key, hold/backlight key and the
power on/off key.
Calibration/Sound Key
A short press will activate the sound function. A long press
(more than 2 seconds) will activate the calibration function.
Periodic checking should be conducted to this instrument. If it is out
of alignment, recalibration will be necessary. This key pad is used for
horizontal and vertical calibration of the instrument. See the
“Self-Check and Calibration” in section 6.
Push the Cal/Sound a short press to turn on the horn (symbol
should be displayed). Push again to turn off. Horn will start a slow
beep at 10º and 80º and beep faster the closer you get to 0º or 90º.
Once the instrument hits 0º or 90º, you will get a steady tone.
Push the MODE key to switch from one construction language
to another. This controls which construction language your
electronic module will measure in. Your level has the capability to
measure in Degrees, Percentage of slope, Millimeters per Meter, Inches
per Foot (Slope/Pitch) in decimal form and Inches per Foot in fractions
of an inch. A symbol on the upper right of the screen will display
which MODE you are currently in.
Hold/Backlight Key
Set the level in place and press this key a short press to enter
into the hold status, record the current angle of the flashing
display, the displayed value will not change. Press this key again to
release the hold and the data will vary according to slope. A long
press (more than 2 seconds) will turn on the LCD backlight.
Power On/Off Key
Power on and off the instrument by pressing this key.
Automatic Shut-off
This instrument will shut-off automatically if no operation is received
within 20 minutes.
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Horizontal Accuracy Check
1. Turn on the digital level and put it on a smooth and level
surface as shown in figure 1. Wait 10 seconds until the display
digits are stable and record the degree reading.
2. Rotate the digital level 180º in the same plane, see figure 2,
wait 10 seconds until the display data is stable then record
the second degree reading.
3. Turn over the digital level in the same plane, figure 3, wait 10
seconds and record the third degree reading when it is stable.
4. Rotate the digital level 180º in the same plane, figure 4, wait
10 seconds and write down the fourth degree reading when
stable.
5. Of the four degree readings, if any two of the values have a
difference over 0.2º, the unit must be recalibrated.
1. Turn on the digital level and put it on a smooth and vertical
plane as shown in figure 5. Wait 10 seconds until the data
reading is stable and then record the angle degree.
2. Rotate the digital level 180º on the same plane, see figure 6,
wait 10 seconds until the display data is stable then record
the second degree value.
3. Turn over the digital level in the same plane, figure 7, wait 10
seconds and record the third degree value when it is stable.
4. Rotate the digital level 180º in the same plane, figure 8, wait
10 seconds and write down the fourth degree value when
stable.
5. Of the four degree readings, if any two of the values have a
difference over 0.2º, the unit must be recalibrated.

surface, figure 9. Press and hold in for 2 seconds the Calibration
key, -0- will show on LCD display. Wait 10 seconds then press the
Calibration key again, the LCD will show -1-.
2. Rotate the digital level 180º on the same plane, figure 10, wait 10
seconds and press the Cal key until the LCD displays -2-.
