Before using the Scale
All Marsden V-20 scales come complete with plastic platform, plastic base and two
soft handles. There are three easy to use function keys: MEMORY, KG/LB,
TARE/ON/OFF.
The scale can be used in a fixed location or as a portable scale, powered by either
the DC adaptor or with a 9V battery.
If you require any assistance with using the V-20, call the Marsden team on 01709
364296, quoting model number V-20 and the serial number, which can typically be
found on the underside of the scale.
Before use, ensure the scale is on a flat surface. An un-level surface for weighing
could result in inaccurate readings.

Operation
Switching the Scale on/off
To switch the V-20 on, press TARE/ON/OFF.
Once the scale shows a line of zeros, it is ready to use.
To switch the V-20 off, press and hold TARE/ON/OFF for three seconds.
Using the Hold function
The Hold function allows you obtain an accurate weight reading, even if the animal
is moving on the scale.
The Hold function is automatic, meaning the display will lock without prompting.
The arrow at the bottom left of the display will flash briefly and then remain on the
screen, indicating that an accurate weight is being held on the screen.
To disable the Hold function once you have finished weighing, press
TARE/ON/OFF.
Using the Tare function
The Tare function allows you to remove unwanted weight from the display, such as
a towel or blanket.
With the scale switched on, place the item you wish to tare off onto the platform.
Press TARE/ON/OFF. The display will show zero, and when you remove the item, a
minus reading.
When you place an animal to the scale the weight reading will show the weight of
the album, minus the weight of the item you removed using Tare.
To cancel the saved tare weight, switch the scale off.
Switching between kg, lb and lb:oz
At any time, with the scale switched on press KG/LB to toggle between kg, lb and
lb:oz readings. The unit of measurement will be indicated at the top of the display.
Using Memory Recall
Press MEMORY to store a weight reading showing on the indicator.
With the scale switched on and with a reading below 1kg, press MEMORY to recall
one previously stored weight reading.
