this manual before each use.
•Do not use in the presence of flammable materials.
•Operating at other voltages and frequencies than specified could damage the equipment.
•If the “LO BAT” indicator activates, for accurate weighing, connect the scale to an
AC power source as soon as possible.
•Para evitar lesiones, nunca deje al animal solo mientras esté en la balanza.
•Para evitar lesiones, no traslade la balanza mientras el animal está en la bandeja de pesaje.
•Para un pesaje exacto del animal, la balanza debe ser colocada en una superficie plana, estable.
•Para un pesaje exacto, verifique antes de cada uso la apropiada operación según los procedimientos
descritos en este manual.
•No use en presencia de materiales inflamables.
•Operando en otros voltajes y frecuencias que los especificados puede hacer daño al equipo.
•Si el indicador de “LO BAT” se activa, para un pesaje exacto, cambie las baterías o conecte la balanza
a una fuente de energía CA, lo más pronto posible.
•Pour prévenir toute blessure accidentelle, ne laissez jamais un animal sans surveillance sur la balance.
•Pour prévenir toute blessure accidentelle, ne transportez jamais la balance avec l'animal sur le plateau.
•Pour obtenir une lecture du poids exacte, placez la balance vétérinaire sur une surface plane et stable.
•Pour obtenir une lecture du poids exacte, vérifiez le bon fonctionnement de la bascule en appliquant la
procédure décrite dans ce manuel avant chaque utilisation.
•Ne pas utiliser en présence de substances inflammables.
•Le fonctionnement sous d'autres tensions et fréquences que celles spécifiées dans ce manuel est

GENERAL
The Digital Veterinary Scale, model
H740-10, uses sophisticated microprocessor
technology. Each precision instrument is
designed to provide accurate, reliable and
repeatable weight measurements with features
that make the weighing process simple, fast and
convenient.
The scale is set up to use motion-sensing
weighing technology to determine the actual
weight of an active animal. Weight is displayed
on the indicator in either pounds or kilograms.
The scale includes a specially designed
removable rubber mat for easy cleaning.
Power supply:
The scales operate either on a rechargeable
battery or an AC adaptor.

OPERATION INSTRUCTIONS

P 9
Using the Tare Function
The Tare function is used to deduct accompanying weight (such as collar or bandaging
attached to the animal). Tare function can be set either manually or automatically:
1.Manual mode:
The scale display must show 0.0lb/kg on the right
hand side of the display and ZERO in the upper left
hand corner.
Press the BMI/tare key for 3 seconds and release
immediately once the tArE (tare) message flashes
on the display.
A 33lb /15.0 kg default value will appear which can
be increased or decreased (according to the weight of
the product) by pressing on the last two keys.
The upward arrow increases the value; and the
downward arrow decreases value.
Once you have reached the weight value required
press the BMI/tare key and the programmed value
will appear with a minus sign next to it.
Continue with the weighing process as required. To
cancel the manual tare operation, remove all weight
from the scale and press the Tare key for 3 seconds
and release immediately.
2.Automatic mode:
1. With the scale set to 0.0lb/kg, place the extra load on the scale. The display shows
"WEIGH," and then the weight of the load.
2. Press and hold the TARE key for three seconds. The display returns to 0.0lb/kg and
"TARE" appears on the left side of the display.
3. Remove the load from the scale. The weight of the load appears with a minus symbol
to the left.
4. Place the animal on the scale with the load. The display then shows the animal's
weight without the weight of the load.
5. The weight of the load remains stored in memory, so you can continue to weigh
animals with the same tare weight..
6. To cancel the tare weight, remove all weight from the scale, and press the TARE key
again. "TARE" then disappears from the display. The tare weight is also cancelled
when the scale is turned off.

Press the Reweigh button and release, the display will show CAL
and will conduct calibration calculation.
FACTOR = x.xxxxx will appear on the LCD display
Press the Reweigh key and SAVE will appear on the LCD display
Press Reweigh again and dOnE will appear on the LCD display
Note: If kg/lb is pressed at this stage the calibration sequence is
completely cancelled
StArt appears on the LCD display and the scale returns to regular
weighing mode.
