4.0 SETTING UP THE SCALE
•Take the scale out of the box.
1. Locate the 4 screws (2)
2. Place the cable (4) through the pillar
(3).
3. Insert the 4 screws (2) through the
holes on the pillar bracket and secure
the bracket to the indicator (1),
4. Make sure the screws are securely
tightened.
5. Place the cable (4) into the tube
support (6) on the scale base.
6. Insert the pillar (3) into the tube
support (6).
7. Rotate the pillar to position the
indicator (1) in the direction desired,
and then secure using the 2 screws
(5) into the fixing tube (6).
8. Locate the load cell cable (13) ready for
connection

Page 6
9. Place the indicator cable (4) and the
load cell cable (13) together near the hole
on the base (16).
10. Plug the two connectors (15) together.
11. Position the connector inside the base
(16).
12. The cables should be fixed to the base
using the clip provided (14).
13. Locate the fixing bolt and washer
(10) used to secure the height rod to
the scale base (11)
14. Locate the height rod (7) onto the
fixing points (9) of the upper and lower
brackets (8) & (12).
15. Secure the bolt and washer to the
bracket on the base (10)
16. Tighten the bolt on the upper
bracket (9).

5.0 FUNCTION
5.1 WEIGHING
•Place the Scale on an even floor and press the [On/Off] key.
•The instrument performs a self-test after which it is ready for operation.
•Press the [On/Off] key and the machine switches off.
•The person to be weighed can step on to the platform once the scale shows
0.0 on the display. The weight will be display in Kg. or lb. depending on the
units chosen by the user.
•If the weighing value is to be tared press the tare key to remove the weight
value from the display.
•Press the [Units] key for changing the weighing unit to kg or lb. The LED will
indicate the chosen weighing unit.
•Overload display: When “
FULL ” appears on the display, it shows that the load
on the platform is over the maximum capacity. Under these circumstances, it
is necessary to reduce the load otherwise the sensor or the platform will be
damaged.
•Hold Function: To lock the weighing result, press the [Print/Hold] key. The
LED will flash until a stable reading has been obtained and then it will light up
constantly. The weight will be displayed until the hold time has expired (see
Sec 7.0) or to manually release the function, press the [Print/Hold] key again.
•Print Function: To send the weighing result to a printer or computer press the
[Print/Hold] key when the [Print/Hold] key has been set up in the parameter
section to work as print function.

5.2 MEASURING HEIGHT
•To measure someones height, it is necessary to extract the measuring rod and
place the height arm on top of the head of the person being measured.
•For shorter heights the height arm can be released by pressing the red button
on the top of the height rod, and then moving the height arm to the lower
section of the height pillar.
•The height is read on the bar at the top of the support. The height can be read
in either centimetres or inches,
5.3 MEASURING BODY MASS INDEX (BMI)
•Once the height has been determined it is possible to enter the height reading
into the display ready for the scale to compute the BMI.
•Press and hold the [Unit/BMI] key to enter the BMI mode. The display will
show the last height value used, “Cm123” or “In123” depending on which
weighing unit you are currently using.
•The height entry unit (Cm or In) will be flashing to show you which unit you are
currently in, use the Up arrow key to change the height entry unit between Cm
to In as required
•Enter your height using the arrow keys, the [Print/Hold] /key will increment
the flashing digit, the right arrow, the [Unit/BMI] /key, will move the flashing
digit to the adjacent digit.
•Press the [Tare]/↵
↵↵
↵key to confirm the value.
•The display will now show the BMI based on the current weight on the scale
and the height entered.
•Press the [Unit/BMI] key to exit the BMI mode and return to normal weighing.
•The Hold function will work as described above whilst in the BMI mode.

6.0 CALIBRATION
Before calibrating the scale, you should ensure that you have a suitable known weight for
calibration.
1. When in normal weighing mode with the scale at zero press and hold down [TARE] and
[ON / OFF] keys to enter the calibration mode.
2. If the calibration switch is in the off position on the main PCB inside the scale, the
indicator will show “CAL.OFF” and then exit this mode. If the indicator shows “CAL-?”,
the scale is ready for calibration.
3. When the indicator shows “CAL-?”, press the [TARE] key to confirm and go to next step,
or press the [ON / OFF] key to exit the calibration mode.
4. When ‘0.0’ is displayed the scale will begin to calibrate the scale’s zero-point. Ensure
that there is no load or weight on the scale’s platform. Press the [TARE] key to confirm,
or press the [ON / OFF] key to exit this mode.
5. A few seconds after the [TARE] key has been pressed in step 4 the scale will show
“300.0” and the kg LED, or “600.0” and the lb LED depending on which unit you chosen,
this is the default calibration weight from the factory. Press the [UNIT] key to select the
calibration weight unit that you want to calibrate in. Press the [ON / OFF] key to exit the
calibration mode at this point or press the [Print/Hold] key to choose a different
calibration weight value (50kg, 100kg, 150kg, 200kg, 250kg, 300kg or 100lb, 200lb,
300lb, 400lb, 500lb, 600lb); Then put on the weight that you selected and press the
[TARE] key to confirm the chosen standard weight that was selected earlier. The
displayed data will flash on the display and if the scale accepts the calibration data it will
calculate and store the information into the EEPROM. If an error has occurred, the scale
will display “CAL. Er” and return back to step 4 for re-calibration. If the loaded weight is
not within the range of 95% to 105% of the weight value you selected, the scale will not
calibrate but display “CAL. Er” and return back to step 4 for re-calibration. )
6. Check the calibration by putting the weight that you calibrated at back on the scale, if it
is off repeat the calibration process again.

7.0 USER PARAMETERS
This indicator has 4 parameter settings that can be selected.
1. When the scale is in normal weighing mode, press and hold down the [ON / OFF] key
and the [UNIT] key for 3 seconds until ‘Setup’ is shown on the display.
2. When in the SETUP mode, press the [Print/Hold] key to change the flashing digits, and
[TARE] key to confirm the flashing digits and move to the next parameter setting. Press
the [ON / OFF] key to exit the set up mode.
