using the three screws and connect the cable by fixing the
connector.
•Slide the pole cover to the bottom.
•Remove the screw at the top of the pillar and turn the
indicator panel to 180 degree. Tighten the screw until the
indicator panel is secured.

•If the scale is still displaying a small weight when there is no
load on the platform, it needs to be zeroed. Press the
[Tare/Zero] key to zero the display. The arrow above Zero
will be on. If the zero display is not achieved then the scale
may need to be re-calibrated.
•If the weighing value is to be tared to obtain the net value,
press [Tare/Zero] again. The arrow above Tare will be on.
•The person to be weighed can step on to the platform now.
The weight will be displayed in Kg or lb depending on the
units chosen by the user.
•Units: Press the [kg/lb] key for changing the weighing unit to
kg or lb. An arrow will indicate towards the chosen unit.
•Backlight: The scale has an automatic back-light which is
switched on whenever time the scale is in use.
•Overload display: When “OL” appears on the display, it
shows that the load on the platform is over the maximum
capacity. It is necessary to reduce the load otherwise the
sensor or the platform may be damaged.
•Hold Function: To lock the weighing result, press the [Hold]
key. The arrow indicator will point towards Hold and it will
show a steady reading even if the person on the platform is
moving or goes away from the scale and will not allow the
next weighing. To release the function, press [Hold] again.
•Do not press the [On/Off] key if you do not want to weigh as
pressing the [On/Off] key will switch the scale to ON.
6.0 MEASURING HEIGHT
•While measuring the height, it is necessary to pull up the
measuring board at a right angle with the inside tube.
•When the tube is pulled out straight, it is sufficient to
measure the height from 80 to 126 cm. The number can be
obtained upon the conjoint place where the upper part of
middle tube screw meets with the inside tube scale.

•Further, if the middle tube is pulled out straight, it is possible
to measure the height from 126-190 cm. The reading can be
obtained at the conjoint place where the upper part of outside
tube screw meets with the middle tube scale.
7.0 MAINTENANCE
•Do not dismantle the weighing machine without following the
necessary instructions.
•Do not jump while standing on the load-bearing board. This
may damage the sensor inside.
•Do not move the weighing machine violently and abruptly. It is
recommended to move and put down the weighing machine
gently.
•It is suggested to wipe the stains with soft cloth soaked with
detergent and to wipe later with soft cloth too. Do not use
organic solutions and boiled water to wipe the stains. Do not
use water for cleaning.
•Keep the weighing machine in a dry and clean environment. Do
not expose it outdoor or use it in locations near fire, under
direct sunshine or with high temperature.
•When lifting the height meter, it is suggested to pull it straight
along the pipe without using excessive force.
•The [On/Off] key on the screen board only switches off the
screen power instead of the entire power to the weighing
machine. Therefore, it is necessary to switch off the main
power supply when the weighing machine is not in use for a
long time. Otherwise the battery may be damaged as a result of
over-discharge.
