1. Carry out the check weigh procedure annually or bi-annually; note the results
  2. Select 0.5kg increment on the weight read-out unit, & retain this 0.5kgs (1.1 lbs) setting “at all times”
  3. Use “Weights & Measures calibrated ballast weights”, ideally to a total weight of 60kgs (132 lbs) ; 4-5 x large liquid containers would also be suitable, filled with water or sand, & calibrated (to the nearest 0.5kg (1.1 lbs) at a licensed food outlet, such as a farm shop.  Please do not use any type of produce/horse feed, as they may have dried out since their packaging, & therefore will have lost weight. Mark the calibrated weights on the containers to the nearest 0.5kg (1.1lbs), and securely store them.]
  4. Place the known dead weights in the “middle” of the weighing platform & note their weight on the weight read-out unit
  5. The registered weight must fall within +/-1% of their weight, to be performing within the Horse Weigh accuracy guarantee – for example
    • for 60kgs (132 lbs) of dead weight, the registered weight must read between 59.5kgs (131 lbs) & 60.5kgs (133 lbs)
  6. If not, then inspect for the following:
    • there are no cuts in the blue cables
    • the blue cables are not caught under the black rubber feet of the weighing platform & “all the black rubber feet are very tight”
    • the blue cables are correctly attached/ fully screwed in, to the weight read-out unit
    • the weighing platform is not touching any walls or barriers, & not rocking. Please note, to weigh on a gentle gradient is permitted.
    • there is no build-up of materials/ small stones / chippings underneath the weighing platform/ within the 4 black rubber feet assembly
    • with the “Mini Tokyo & Mini Tokyo-Thoroughbred” models, the underneath hands should be very tight, and slightly difficult to “lock into position” when assembling them. If not, refer to their assembly / breakdown instructions

If any of the above 6 scenarios are found, then correct, as require

7. Carry out Steps 2 – 5 again; if still not registering within +/-1% of the known dead weight, contact Horse Weigh (see below) or the Horse Weigh After Sales Service Department –


Please Note – at the time of manufacture, the weighing platform loadbars are calibrated; this lasts for their life time, as their calibration technology is sealed. However, if a major repair is required at the Horse Weigh factory/ at one of the Horse Weigh After Sales Service Centres, then prior to their re-use, the loadbars are re-calibrated


                               Steps 1-7 then become applicable once again
