measurement technology makes the effective measurement distance can reach to 30 meters. The tool
has the function of long distance measurement. And it is easy to operate and clear to display. It is an
ideal tool for building, decoration industries (for example, land agents, upholstery designers and
craftsmen, etc)
KC-200 bidirectional ultrasonic distance measurement is the Class II laser tool conforming to
EN60825-1 safety rule.

OPERATION GUIDE
Battery installation
Open the battery compartment door on the back of the tool, and plug one 9 Volt block battery
onto the battery connector and put the battery back to the compartment and close the door.
Distance measurement
zMake the induction hole of the tool face against the measured object (e.g. the wall) and keep the
tool vertical to the measured object; make sure the point of the level vial stands between the two
lines of the level vial by adjusting the position of the unit.
zPress the READ key to start the tool, the instrument is ready to work.
zPress the READ key again to get the measured distance. There are left measuring and right
measuring result respectively on the upper row. The addition of left measuring result and right
measuring result will display on the lower portion meantime. The laser beam indicates the
measured surface.
3
zKeep pressing the READ key and move the tool to get the dynamical readings, and the measured
distance will be displayed on upper portion of the screen
zPress the BASE key once to transform measurement base. Press the key every time and the base
point are the following five ways in turn: starting from the middle then do bidirectional
measurement、starting from the left then measure to the right、starting from the right then measure
to the right , starting to the left then measure to the left、starting from the right then measure to
the left. The default state is for bidirectional measurement .
zMidpoint indication: At the mode of bidirectional measurement, when the unit detects the
midpoint ( the distance of two sides is equal), the buzzer will sound. Meanwhile the central base
symbol and two ultrasonic symbols on the display will twinkle.
zUnit transform: Keep pressing RM key for 2 seconds to select measurement unit: British unit
or the Metric unit. (the original unit is Metric unit)
●Shut the tool: Keep pressing the BASE for 2s to shut the tool. And if there’s no action in 60s, the
tool will turn off automatically.
Tips: A. The measured object must be a normative horniness surface and without barrier.
B. To ensure exact measurement, the measured surface should be smooth, bigger area and of
homogeneity.
C. If the measured surface is too small, abnormity or the surface is soft, a board should be
placed on the surface of measured object.
D. The unit can’t measure through the glass.
E. When measuring, the tool should keep a distance away from the measured object at least 2
feet (50cm).
F. To ensure exact measurement, the temperature of the tool should be same with the
temperature of environment
G.. If the tool has been off automatically or by hand, just restart the tool after 5s.
Addition (W/O using M memory)
zPress READ key for measurement and the measured value is displayed on upper portion of the
screen (note: when bidirectional measurement,the addition of left measurement result and right
measurement result will display on the lower portion of the screen);
zPress +/= key to enter the addition mode, and the “+” icon will appear on upper portion of the
screen. At the same time, the addition of primary data on lower portion and measurement result
now is displayed on the lower side of the display.
4
Notes: 1. When enter “+” operation for the first time, the primary data will be seemed as “0” to
do addition.
2. Pressing +/= key will be of no effect, when the tool with no any measurement (the
data is 0.00m on the upper portion).
3. If the data is continuous dynamic measuring result, the last display data will enter into
the “+” operation.
zPress READ key again for second time measurement, the measured value is displayed on the
screen;
zPress +/= key again to display the new sum on the lower portion of the screen;
Note: If continuously press the +/= key for 2 times, the addition operation will be canceled,
all the anterior computation result will clear away.
zRepeat the steps:3～4 above can continue accumulation.
Addition (using M memory)
zPress the M key to save the first measured result, and the “M+” will appear on the
rightportionofthescreen.
zPress the READ key for new measurement and display the result.
zPress the RM key to recall previous measurement for the addition (displayed on the bottom of the
display), and at the same time, the “M+” icon disappears and the stored memories will be
automatically eliminated;
5
zPress+/= key for accumulation, the result of memory data and measurement data will display on
the lower portion of the screen. At the same time, “+”icon will display on the upper portion of the
screen.
zNotes: 1. If continuously press the +/= key twice, the addition operation will be canceled, all
the anterior computation result will clear away.
2.At this moment, if pressing M key again, the tool will memory the result on the bottom
of the display. The tool will add with accumulation.
Area
zPress MODE key to enter area mode, and the " "will appear on the display.
zThe length character " " on the display will blink with the frequency of 2Hz showing the
length measurement you will be firstly taking. Press READ key to take length measurement and
display on the screen. (Step 1);
zThe width character " " on the display will blink showing the next measurement to take.
Press READ key to take width measurement and display on the screen (Step 2);
6
zThen the area character" "on the display will blink, Pressing READ key to take the area
result and display on the lower portion of the screen. At this moment, the " " icon won’t
blink again. (Step 3);
zPress the READ key again will toggle back and forth between the length and width, area
measurement result and corresponding icon " " " " and" " will display
and blink with the frequency of 2Hz on the screen, meanwhile the measurement won’t work.
●Press MODE key again to clear the data on the portion of the screen, then can begin the new
calculation of area.
Addition of area under area mode:
zPress the M key to save the calculated area on the lower portion of the screen, at the same time,
the “M+” icon appears on the screen;
zPress MODE key again to begin the second time measurement and computation (follow step 1, 2
and 3 under the area section);
zAfter getting the desired area of the second time computation, press +/= to enter the addition
mode. A “+” icon would appear on LCD.
Note: If continuously press the +/= key for 2 times, the addition operation will be canceled and the
icon +/= will disappear (Press+/= key shortly for one time will enter into addition, Press+/= key
7
shortly for two times will cancel the operation. Then press again will toggle back and forth between:
add----cancel----add).
zPress RM key to recall the first calculated area and display on the lower portion of the screen for
the addition. The “M+” icon will disappear and the stored memory will be automatically cleared;
zPress +/= key again, the sum of both areas is shown on the lower portion of the screen;
zRepeat the steps above to keep adding the measured area.
zRepeat the steps:1～5 above can continue accumulation.
Volume
zPress MODE key to enter volume mode, and the " "will appear on the display.
zThe length character " " on the screen will blink with the frequency of 2Hz showing
length measurement will be taking. Press READ key to take length measurement, the result will
be displayed on the screen. (Step 1)
zThe width character " " on the screen will blink showing the next measurement to take.
Press READ key to take width measurement, the result will be displayed on the screen. (Step 2)
8
zThe height character “H” on the screen will blink showing the next measurement to take. Press
READ key to take height measurement, the result will be displayed on the screen. (Step 3);
zThe volume character " "on the display will blink, Pressing READ key to take the
volume result and display on the lower portion of the screen. At this moment, the " "icon
won’t blink again. (Step 4);
zPress the READ key again will toggle back and forth between the length and width, height,
volume measurement result and corresponding icon " " " " " " and "
"will display and blink with the frequency of 2Hz on the screen, meanwhile the
measurementwon’twork.
zPress MODE key to clear the data on the screen, and then can begin the new calculation of
volume;
Addition of volumes under volume mode:
zPress M key to save the calculated volume on the lower portion of the screen, and the “M+” icon
will appear on LCD;
zPress MODE key again to begin the second time measurement and computation (Follow step 1,2,
