G&G TJ Series User Manual

Operating Instruction Manual of TJ Series Electronic Counting
Weighing Apparatus
1. Overview
TJ series electronic counting weighing apparatus is quality electronic weighing implement
carefully designed and manufactured by the G&G Measurement plant based on highly
accurate sensor, measuring circuit and special monolithic computer system from G&G,
featuring advanced technology, excellent materials, exquisite workmanship and strict testing
means, thus providing this series electronic counting weighing apparatus with the following
perfect advantages:
1. High accuracy and sensitivity with fast response.
2. Use of highly accurate strain sensor for weighing, eliminating the defect that generally,
highly accurate electromagnetic type electronic weighing apparatus can not weigh iron,
nickel and other magnetic-conductive substances.
3. Advanced mode of circuit and good materials and workmanship, hence the high
reliability of products, good resistance to interference, long service life, good stability in
long service, and adaptability to poor operating environment and continuous long-term
operation.
4. Functions of automatic calibration, automatic zero tracing, counting, accumulation, tare
and pre-tare, unit conversion, preset quantity alarm and more.
5. Use of green LED display allowing distinct display and visible readings.
6. The electronic counting weighing apparatus allows options of data output interface and
printing button, direct connection with printer for data printing and even direct interface
with computer for data acquisition and statistics while the computer controls the
operation of the electronic counting weighing apparatus via the interface and conducts
real-time remote control of the electronic weighing apparatus.
7. Rechargeable battery with large capacity which operates continuously for over 36 hours
after one charge, and allows the use of the electronic weighing apparatus during charge,
which does not affect the behavior in service of the weighing apparatus.
