Installation
Locate a weighing site that is well drained. For best weighing results, ensure the weigh
bars and weighing platform are on a level hard surface (i.e. concrete), and free from
contact of any obstruction. Do not use wooden platforms. Make sure the platform
doesn't rock, pack with spacers if needed. If the installation has any flexing or twisting
in the platform, inaccurate weights may occur. The weight should be evenly distributed
over the top of the weigh bars.
When bolting the bars down, also eliminate any twisting of the platform. Avoid bolting
everything down tight. If in a fixed situation, it is best practice to bolt the rear bars to the
concrete, then bolt the platform or crush to the bars, then leave the front bars unbolted
with only guide pins into the concrete. Shim the bars and crate with washers or similar
pieces of metal so that no diagonal rocking motion occurs before tightening all of the
fixings. This will minimize any flexing that could occur.
When weighing animals, be sure that their weight is totally on the weighing surface, and
not leaning on fixed gates, rails, etc. If at all possible use a crush or weigh box, and
place the weigh bars so that the whole structure is weighed. This will eliminate
weighing errors if the animal does lean on any part of the structure
Care and Maintenance
WARNING! DO NOT WELD TO THE WEIGH BARS OR ANY STRUCTURE THAT
THEY ARE ATTACHED TO. The voltage and current from the welder can instantly
destroy the sensitive strain gauges used to measure the weight. Welding currents
create observable damage to the strain gauges, and will void your warranty. Remove
the weigh bars from the structure before attempting to weld.
Care of cables is important to avoid erratic readings or breakdown. Plugs should
be covered when not in use to avoid corrosion of contacts and to prevent moisture
penetrating the cables. Even a thin film of moisture around the pins in the plug may
cause erratic readings.
Do not allow the bars to remain wet or allow a build up of manure inside the bars
for long periods of time. This will shorten the life of the weigh bars, can cause
premature failure and may void your warranty. If the area does remain wet, remove the
weigh bars when not in use. The weigh bars are sealed, and can be hosed out with low
pressure water to keep clean.

- Page 2 Good quality alkaline batteries will power the scale for up to 30 hours running time. Rechargeable AA batteries may be used, but the battery level indicator will not be as accurate. The T10 will turn itself off after 30 minutes if no keys have been pressed or if the weight has not changed.

Page 3: Operation
Load cell 1 Load cell 2 The T10 has a water resistant 10 button keypad for a user interface. An extra large 40mm digit display provides the user with the ability to view the weight at a distance. The display also has other indications that are used at various times. All mode settings and changes are memorized at the time of change, so that the indicator will return to the previous set up when it is turned on. - Page 4 then ready for weighing. This means that no buttons need to be touched if the scale is used for weighing the same thing each time. Tare When pressed during normal weighing, the scale will display 4 dashes (----) and cancel any weight that exists on the weigh bars.
- Page 5 Calibration The T10 has the capability of being calibrated in the field. The electronics in this weighing system is very stable, and this calibration procedure should rarely need to be done. However, if the weights are critical, it is advisable that the scale be calibrated every year or two.
- Page 6 6. ‘Zero weight’ will cease flashing, and ‘----‘ will be displayed for 4 seconds while samples are obtained and averaged from load cell 1 with no load. 7. ‘Test weight’ will start flashing after the samples have been taken, and the default test weight will be displayed.

Page 7: Error Messages
A load bar that has its rated capacity weight applied outputs less than 0.007 volts of signal. Each load cell is sampled independently many times per second, which allows the T10 to continuously monitor any problems that could occur. One of these problems is an overload condition. - Page 8 If there doesn’t appear to be any visible damage after inspecting the installation, contact your supplier or distributor, quoting the error number that appeared. They may be able to help with a cure. The possible error messages are as follows: Error Explanation Possible Cause/Remedy...
