Operating Manual for JJ-B Series of Electronic High Precision Balances
(for following models: JJ100B, JJ200B, JJ1500B, JJ2000B)
1. Overview
Manufactured and well-designed by G&G Measurement Plant, adopting
industrial-class high precision sensors, measurement circuit, a “G&G”
dedicated single-chip computer system, and controlling system, JJ-A series
electronic balances are high-quality electronic weighing machines. Advanced
technology, well-selected, exquisite processing and strict testing make JJ-A
series of electronic balances be possession of following strong points:
- Simple operations.
- Integrated water level on the scale
- High precision, hypersensitivity and fast reaction speed
- High quality, strong anti-interference capability, long life, long-term
using stability, adapting to the adverse environment and long hours
continuous work
- With auto calibration
- Unit conversion feature: in seven units between arbitrary conversions
- Balance is targeting output data interface and can be connected directly
to the printer and computer to collect and analyze the data. The balance can
even remote controlled by computer.
In general, with high precision, high stability, high reliability and high
efficiency, the “G&G” electronic balances has widely replace the traditional
mechanical, tray balances. The “G&G” electronic balances have been widely
used in all callings, in different kinds of measurement and test. Those have
played an important role in improving products quality, cost-effectiveness
and efficiency.

3. Operational Method
3.1 Turn on the power. Open the switch. The displaying windows
displays from “F----0” to “F----9” and after a certain time for stabilizing,
“0.0” appears; Then preheats for 15 minutes. Instability of the displaying
at every beginning is normal; after a certain time, the displaying will stabilize.
3.2 With empty scale platform, the displaying deviates from zero,
pressing “TARE” key, then the displaying will return to zero.
3.3 If the scale has not been used for a long time or just bought, the
scale should be calibrated. Firstly, the scale is fully preheated (over 15 min.)
with empty scale platform. Then press “CAL”, the displaying window shows
“CXXX” and the balance will automatic calibrate (XXX should be the
weight of standard weights). At the same time, only place calibrating weights
on the scale platform. After stabilizing, the scale displays the weight of the
calibrating weights; till now the calibration is completely finished and the
scale can be normally used. If press “CAL”, but display “C----F”, which
indicates the Zero point is not stable. Then re-press “TARE” to make “zero”
point stable; and re-press the “CAL” to carry out calibration.
