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 “ 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 some ones 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 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 recalibration. )

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.

0.0’ is displayed the scale will begin to calibrate the scale’s zero-point.

7.0 USER PARAMETERS

This indicator has 4 parameter settings that can be selected.

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.

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.

8.0 RS232 COMMUNICATIONS

The Interface parameters are:

Connection details are:

RS-232 output of weighing data ASCII code 9600 Baud rate (fixed) 1 start bit, 8 data bits,1 stop bit

Connector: 9 pin d-subminiature socket Pin 2 Output Pin 3 Input Pin 5 Signal Ground

No Parity

8.1 RS-232 connection between the Scale and the Host:

DB9 female

RXD pin 3 TXD pin 2 GND pin 5 Note: Pins 1,4,6,7,8 and 9 are not connected.

The RS232 function will only operate if PH has been set to 0 or 2.

8.2 When Parameter S.F. in section 7 is set to 0 : No RS232 function. The scale will not transmit or receive any data although the scale is equipped with RS232. The RS232 function can be only activated when the scale is in normal weighing mode.

Page 11

Page 14

8.3 When Parameter S.F. in section 7 is set to 1 : Continuous output of the current displayed reading and unit, and no data is received.The output format is as below:

Or <LF>< reading, minus, decimal point, weight unit>NT<CR><EXT>

8.4 When Parameter S.F. in section 7 is set to 2 : Manually outputs displayed data when PRINT is pressed. The output format is as below:

Or <LF>< reading, minus, decimal point, weight unit>NT<CR><EXT>

8.5 When Parameter S.F. in section 7 is set to 3 :

The baud rate and data format are fixed with responses to serial commands being within 300 milliseconds. One second should be adequate for use as a time-out value by a remote (controlling) device.

8.5.1 The length of the weight field will be a 7 digit weight data, one for minus sign, one for decimal point, two for measuring unit (e.g. “lb”, “kg”). Units of measure abbreviations are always lower case.

If the weight is overcapacity, the scale will return nine ‘^’ characters (the field of

minus sign, decimal point, weight data is filled by ‘^’).

If the weight is under capacity, it will return nine ‘-’ characters (the field of minus sign, decimal point, and weight data is filled by ‘_’).

If the zero point has an error, it will return nine ‘-’ characters.

The character will be ‘-’ for negative weight or a space character for positive weight. A minus sign follows after the first digit.

Unused leading zero’s before digits are suppressed.
