• It is an accurate electronic device with advanced design and stable performance.
• It is designed to measure both the weight and the height of a person.

TECHNICAL SPECIFICATIONS

DISPLAY AND KEY DESCRIPTIONS

[On / Off

/Zero]

| To turn the scale on or off.

To zero the scale if the display drifts from zero.

[Tare]| To tare the scale, if necessary.
[Units]| To toggle the weighing unit between Kg and Lb.
[Print / Hold]| To lock the reading even if the person to be weighed is moving and also to print the weight details out.
DISPLAY| DESCRIPTIONS
---|---
Kg| Indicates when the scale is weighing in Kilograms.
Lb| Indicates when the scale is weighing in Pounds.
Hold| Indicates when the scale has held the weight reading shown on the display. It will flash until it locks into the stable reading which it will then remain on constantly when it has held the displayed reading.
| When the battery is low, this symbol will be light up. Connect the adapter to recharge the battery.
CH| The charge light will be on when the battery is recharging.
AC| This indicates when the scale is being used with the AC adapter.
ZERO| This indicator will be displayed in the left corner when the scale reaches zero.
NET| The Net weight is displayed, Tare weight is at zero.

SETTING UP THE SCALE

• Take the scale out of the box.
• Unwind the load cell cable (number 2 on the diagram).
• Run the cable up through the pillar from the base of the scale.
• Use the 4 screws (number 3 on the diagram) to mount the pillar to the indicator.
• Connect the plug and socket (numbers 6 and 7 on the diagram) and insert the pole into the pole holder.
• Secure the pole to the pole holder by inserting the 2 screws (number 9 on the diagram).
• Secure the height rod into the height rod holder (numbers 4 and 8 on the diagram).

FUNCTION

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. To 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. (Print function is only applied for scale with RS232 interface)

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 form 80-136cm. 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 136-210cm. The reading can be obtained at the conjoint place where the upper part of outside tube screw meets with the middle tube scale.

MOTHER AND BABY WEIGHING FUNCTION

• The MDW scale allows users to weigh the mother and then weigh the baby being held in the mother’s arms. To operate the function, have the mother step on the weighing pan and wait for the weight to be stable.
• Then press the Tare button. The display should read Zero.
• Have the mother hold the baby in her arms whilst she stands on the scale. The weight displayed then is the weight of the baby.
• The mother can now get off the scale. Press the Tare button to clear the mother’s weight from the memory.

CALIBRATION

Before calibrating the scale, you should ensure that you have a 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, showing the calibration switch is in the on position. If the calibration switch is in the Off position open up the indicator and move the switch to the On position. See diagram on page 8.
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 ‘250.0kg’ or ’500.0lb’ 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 or 100lb, 200lb, 300lb, 400lb, 500lb); 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.

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.

Note: The indicator pin1,4,6,7,8 and 9 are not connected.

The RS232 function will only operate if PH has been set to 0 or 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.
• 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: < reading, minus, decimal point, weight unit>GR Or < reading, minus, decimal point, weight unit>NT
• 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: < reading, minus, decimal point, weight unit>GR Or < reading, minus, decimal point, weight unit>NT
• 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.
• 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.
