I. Feature & Function
LLRMM30 laser ranging detector is an
essential accessory for line lasers to detect
the position of the laser signal emitted by the
line lasers. Used in conjunction with the line
laser to give horizontal and vertical
reference plane quickly and accurately.
※Digital display the laser line position
exactly;
※Large detecting window;
※TFT LCD and high-brightness LED
display simultaneously;
※Ranging function
※Suitable for various types of line lasers
Both red and green lasers can be used;
※Strong magnetic attachment function.
II. User Security

1. Switch on/off
Press once, the LCD displays the instrument
model and version number (Figure 3), the
LED indicator lights up from top to bottom
and then goes out ; the buzzer emits a “didi”
power-on prompt, and then enters the
normal detection state. Shown in Figure 4.
Figure 3 Figure 4
2. Detection accuracy mode selection
Short press the key in the power-on
state, and the instrument will switch
6
between fine measurement (±1mm) and
coarse measurement (±3mm) modes. The
detection accuracy indicator on the LCD is
shown in the figure below.
As shown in the figure: the top one is the fine
measurement, the bottom one is the coarse
measurement;
Figure 5
3. Short/long distance mode selection
When the instrument is turned on, the
instrument is in the long-range mode, if you
want to receive strong signals, you need to
hold down the key to switch to the
short-range mode to receive signals; There
are text prompts at the top left of the screen:
Far, Near.

4. Sound state selection
Short press the key in the power-on
state, and the instrument will switch
between sound and silent state. The sound
indicator on the LCD is as shown in the
figure below.
Figure 6
sound silent Prompt: The
sound and silent state is for the sound
indication when receiving; the key tone will
not be turned off;
5. LCD backlight function
The lighting is on when it is turned on, and
the backlight of the round blister is also
turned on. If the laser signal is not received
within 2 minutes, and there is no key
operation, the backlight will automatically go
out. Once the laser signal is received, or
8
there is a button operation, the backlight will
automatically turn on.
6. Value display & unit switch function
Long press to switch the value unit.
On the left corner of the screen displays:M, Ft.
M means meters, and Ft means foot.
7. Posture recognition and display flip
When the instrument is used upside
down, the instrument will automatically
recognize the posture and turn the display
on the LCDupside down to facilitatethe user
to read the indication status and measured
value;
8. Laser detection
The meaning ofthe information displayed on
the LCD when the instrument detects the
laser is as follows:
9
a. The laser line is on the upper part of
the zero position, and the lower indicator
LED is long on, and the instrument emits a
quick short tone.
Example: The laser line is emitting 1mm
above the zero line, the LCD displays an
upward arrow, and the
offset distance value
is 1mm.
Figure 7
b. The laser line is at the bottom of the
zero position, the upper indicator LED is on,
and the instrument emits a slow short tone.
