MAINTENANCE AND GENERAL CARE
Repairs and Servicing should only be carried out by authorised service
agents.
There are no user serviceable parts in the weighing scale itself.
The mains power adaptor fuses that are not accessible.
When the adaptor is plugged into the mains supply a Green LED should
illuminate to indicate that the adaptor is functioning correctly. If the LED
does not illuminate then the scale should be checked by competent
personnel.
The weight indicator contains an internal rechargeable battery pack; this
should only be replaced by authorised service agents. Under normal
operating conditions the batteries should last for several years.
We would recommend using alcohol based wipes or similar when
cleaning the scales.
Please do not use large amounts of water when cleaning the scales as
this will cause damage to the scales electronics, you should also refrain
from using corrosive liquids or high pressure washers.
Always disconnect the scales from the mains power supply before
cleaning.

OPERATOR INSTRUCTIONS
SECTION 1 - BASIC FUNCTIONS
1.1 SWITCHING ON THE SCALE
Press the ON button firmly.
The scale will first test all of the
display segments.
The scale will now show its current
software version number.
The scale will now go into weighing
mode and should show 0.0kg on the
display.

5
1.2 SWITCHING OFF THE SCALE
Press the OFF button.
The scale will power down.
1.3 SETTING THE SCALE TO ZERO
If for some reason the scale shows a
reading other than 0.0kg then it can be
reset to zero (2% of capacity).
Press the zero key once.
The scale will return to 0.0kg.

6
SECTION 2 –ADVANCED FUNCTIONS
2.1 HOLD FUNCTION
Press the HOLD button once.
The person should now get on to the
scales.
After a few seconds the scale will lock on
the person’s weight, the person can now
stand off the scale and the weight will
remain.
Press HOLD again to unlock the weight
and return to 0.0kg

7
2.2 BMI (BODY MASS INDEX) FUNCTION
For this example we will assume we have a person weighing 60kg who is
170.0cm tall.
In normal mode, press BMI key to enter
into BMI mode.
The display will show the last height
entered and the extreme left digit will
flash. Enter the height by using the
numeric key pad (e.g. 170.0cm). There
will always be an active flashing digit in
the height display (unless the HOLD key is
pressed).
Proceed to weigh as normal. The
instrument will show the weight, height,
and BMI value.
At this time, the weight and height can be
freely changed, and the BMI value will be
automatically calculated according to the
changed weight and height.
Stand on the scale for 5 seconds. Press the HOLD key to lock the weight, height, and
BMI value. Press the HOLD key again to disable the display locking function.
Press the BMI button to return normal
mode and the person can now be taken
off the scale.

8
2.3 SETTING THE DATE AND TIME
Press the HOLD key for 3 seconds to access the time setting mode. The time
period digit that is flashing can be changed by entering the appropriate
number from the numeric key pad. The time period to be edited is selected
by pressing the HOLD key.
E.g. To input 25 December 2008, 8:00 a.m.:
Enter the year. Press HOLD to
confirm and access the date editing
field.
Enter the date. E.g. “12.25” for
December 25th. Press HOLD to
confirm and access the time clock
editing field.
Enter the time (24 hour clock only).
Press Hold and the display shows:
YYYY→MM.DD→HH:SS

2.4 PRINTING FUNCTION
An optional Marsden external printer (Model TP-2100) is available for all models.
When the printeris fitted the patient’s weight, height, and BMI result can be
printed on to a paper roll.
Once the person has been weighed and their BMI calculated, simply press the
print key to produce the following ticket:
GROSS WEIGHT 60.00kg
TARE WEIGHT 30.00kg
NET WEIGHT 30.00kg
PATIENT HEIGHT 100.0cm
PATIENT B.M.I 37. 5

2.5 SCALE ASSEMBLING
Connecting the cables of base and column.
Assembling the bracket of column on the base by four screws
then screwing the foot stand into the column base. Assembling
is complete.

11
2.6 USING & ASSEMBLING: HM200D DIGITAL HEIGHT ROD
The height measure is attached to the scale column as follows:
After assembling HM 200D or 201D with MPPS250, connect the height rod
wire with scale indicator. The connection point between the DP3800
indicator and HM-201D is illustrated below:
Digital Height Measure data cable socket on DP3800 Indicator:
1. Fix the blocks on the column
and tighten the screws.
2. Fix the HM200D or HM201D on
the blocks and tighten the
screws.

12
Insert the HM201D data cable into the socket of DP3800 Indicator before use
and simply pull up the height rod and adjust the head piece according to the
person’s height, HM200D & HM201D will automatically transfer the height
measurement to the scale.
The automatic height measurement also enables the automatic calculation
and display of the Body Mass Index (BMI) of the measured person.

13
2.7 USING & ASSEMBLING: HM200M MANUAL HEIGHT ROD
After assembling the HM 200M height rod, simply pull up the height rod and
adjust the head piece according to the person’s height and key in the height
on the indicator to calculate the persons B.M.I.
1. Fix the block on the column and
tighten the screws.
2. Fix the HM200M on the block
and tighten the screw.

ERROR
MESSAGE
REASON
ACTION
Low battery:
This warning shows that the
voltage of batteries is too low
to use.
Please replace with new
batteries or plug the AC
adaptor for operation.
Overload:
The total load exceeds the
maximum capacity of the
scale.
Please reduce the loading
and try again.
Counting error (too high):
Indicates that the signal from
the load cells is too high.
This error is normally caused
by a serious fault on the
scales i.e. a faulty load cell or
wiring. Please contact the
local Service Representative.
Counting error (too low):
Indicates that the signal from
the load cells is too low.
This error is normally caused
by a serious fault on the
scales such as a faulty load
cell or wiring. Please
contact the local Service
Representative.
Zero count over calibration:
Zero range +10% while
powered on.
Please re-calibrate the
instrument.
* 1
Zero count under calibration:
Zero range -10% while
powered on.
Please re-calibrate the
instrument.
* 1
EEPROM error:
Indicates that there is a fault
with the scales software.
This error is normally caused
by a serious fault on the
scales such as a faulty load
cell or wiring. Please
contact the local Service
Representative.
* 1 –
These errors are usually less serious and can be rectified by re-
calibration; however they can indicate an underlying problem with the
scales. Zero Range is set to 10% of Scale Capacity E.g. Capacity
200.0kg = Zero Range +/-20.0kg
