1.0 INTRODUCTION • The MDW 250L scale is a Digital Physician Scale with Body Mass Index (BMI) readout. • 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 and compute the BMI index. 2.
3.0 DISPLAY AND KEY DESCRIPTIONS KEYS FUNCTIONS [On/Off / Zero] To turn the scale on or off. To zero the scale if the display drifts from zero. [Tare] ↵ [Units / BMI] [Print / Hold] To tare the scale, if necessary. Accept settings as required To toggle the weighing unit between Kg and Lb. and to select the BMI function. Move active digit to the right when required. To lock the reading even if the person to be weighed is moving and also to print the weight details if RS232 interface is installed.
4.0 SETTING UP THE SCALE • Take the Physician 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.
. Locate the load cell cable (13) ready for connection 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.
5.0 FUNCTION 5.1 WEIGHING • Place the Physician 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.
5.2 5.3 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.
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 “[AL.OFF” and then exit this mode. If the indicator shows “[AL?”, the scale is ready for calibration. 3.
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. 3.
8.0 RS232 COMMUNICATIONS (Only applied for scale with RS232 interface) 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 No Parity Connector: 9 pin d-subminiature socket Pin 3 Output Pin 2 Input Pin 5 Signal Ground 8.
8.3 When Parameter S.F. in section 7 is set to 1 : Continuous output of the current displayed reading and unit, and it does not receive any data. The output format is as below: < reading, minus, decimal point, weight unit>GR Or < reading, minus, decimal point, weight unit>NT 8.4 When Parameter S.F. in section 7 is set to 2 : Manually outputs display data when PRINT is pressed.
Polarity character including minus sign for negative weight and a space character for positive weight W1-W7 weight data decimal point U1U2: measure units, kg, lb 8.5.
