INSTALLATION
1. Unpack and place the indicator in a secure position.
2. Install the loadbars.
3. Run the loadbar cables to the indicator,
making sure they are protected from damage.
4. Insert the plugs into the sockets at the bottom of the
indicator. Tighten the retaining collars by hand only.
The plugs can go into either socket. Important:
Keep the plugs and sockets clean and dry.
5. The instrument has an internal battery to power the
system. You can also use the 12 volt battery cable or
Mains adaptor to power the system
6. By connecting the instrument to the power supply
using the battery cable (Bakkie battery) or the AC-DC
Adaptor the internal battery will charge.
- The instrument is reverse polarity protected and
will not work if connected incorrectly.
- The scale will not function properly if the internal
battery is flat or the power supply does not supply
a good 12-volt source.
7. The scale is now ready for operation.

OPERATION
Using the scale is straight forward and logical.
Safety
To avoid damage, never load the scale with more than
the total capacity (2000kg) , i.e. the live weight and
platform must not exceed 2000kg.
The cables must be protected at all times from being
trampled, tugged or knotted.
The Display normally shows the current live weight on
the platform in kilograms.
The Resolution is the smallest weight change that can
be displayed at a particular time or the smallest
division. Normally 1kg (This can be changed by
selecting fine mode)
Switching On
Press display shows LS4
- 0 -

Note: do not stand on the scale while it is busy “zeroing”.
The weight shown on the display is a Live weight and
never locks on a value, when the weight changes the
reading changes. However, if the weight is about half
way between two values, the instrument will calculate
the average weight and this average weight will reflect on
the screen. This function works in the case of an animal
that will not stop jumping. The reading will flicker on the
calculated weight.
Weighing
1. Make sure the indicator is displaying 0kg. If not,
zero the scale again.
2. Move the animal onto the platform making sure it
does not lean or touch any other structure.
3. Wait for the reading to stabilise.
4. The weight is then displayed and can be recorded.
