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.

3.4 The units can be changed between “g”, “ct”, “ozt”, “oz”, “GN”,
“dwt”, “lb”. Press “Units” to change the units during weighting
3.5 If needs to tare, first place the container on the platform, after
stabilizing, press “TARE”; the scale displays “zero”. Then place the article
in container, at this time, it shows the net weight of the article. Remove the
article and the container. The scale shows a negative value of container
weight. Still press “TARE” to return to “zero”
3.6 .Count function
3.6.1 Change the balance modus into count modus according to the
Attachment.
3.6.2 Choose samples. To precisely count the articles, firstly the quantity
of samples for counting should be chosen in according with the weights of
the articles. The quantity of samples can be chosen from “1-10-20-50-100”.
For a small number of articles, the larger quantity of samples, the more
precise.
3.6.3 Place the samples on the pan, the balance will show the total
weights of samples. Then press “Count”, balance will show “1”, and unit
will show “pcs”, which indicate that balance is now counting. And all the
samples are one unit. Then press “Count”, the displaying will show between
1-10-20-50-100. The quantity of articles must be the same with the quantity
of samples, and place the similar articles. The total amount of objects is
showed. Press the “Count” again back to the normal situation.
4. Attachment: settings and meanings
Turn on the Scale by pressing “CAL” key, in order to change the con-
figuration and function. the display shows C1 and the relevant number,
which can be changed. Pressing “CAL” can change the parameters; pressing
“TARE” can change the values of parameters.
4.1 C1------ sensitivity setting 0 1 2 3 4, the larger number is, the less
sensible but the better stable. Default setting is 2 or 1
4.2 C2------filtering strength setting 0 1 2 3, the larger number is, the
lower reaction speed, but the better stable. Default setting is 2 or 1
4.3 C3------Baud rate setting 2(600) 3(1200) 4(2400) 5(4800) 6(9600).
Default setting is 2
4.4 C4------communication setting. “TARE” changes the lower unit.
“COUNT” changes the higher units. This is the first data during commun-
ication. Default setting is 27.
4.5 C5------units change. 0 is for units changing and 1 for printing.
Default setting is 0. Counting is 2.
4.6 Re-pressing “CAL” after setting. Then the balance is auto calibr-
ated to 0.
4.7 Press “TARE” and do not loose till “F----3” (Balance should be
switched on).
All the parameters can be reset to default settings. Re-calibration before
using.
5. Data Transmission
Balance is targeting data output interface RS232C and can be directly
connected to the printer. The following soft wares are needed, when connects
to computer:
3.8.1 Transmission format: serial asynchronous
3.8.2 Serial communication protocol: Baud rat: 600, data: 8 units,
starting: 1 unit, ending: 1unit
3.8.3 Data format:
Starting spaces data symbol ending enter
2unit 7units 3unit 1 unit 1 unit
3.8.4 Check bits: no check bits
3.8.5 Output pins content (9-core socket): 2 pins: RXD 3 pins: TXD
5pins: GND
3.8.6 Computer can control balance though RS232. The orders to
balance are:
1BH+70H: sending data

65
1BH+71H: calibration (like “CAL”)
1BH+73H: Units change
1BH+74H: Tare

7. Cautions for operation
7.1 Using environment: indoor, max. Altitude: 2000m, temperature:
0-40°C, humidity ≤80%, Power fluctuations less than ±10%
7.2 The electronic scale is a precision instrument which needs to be
gently handled during the weighing of articles. Avoid impact and heavy load
on top (never exceed its max. weighing limit). Any forms of impact or
overloading many cause permanent damage to the electronic balance, even
in the use of electronic balance without power supply.
7.3 Place the scale on a firm table for operation, and make sure that the
operating environment of the balance is free of great vibration and interfe-
rence of power supply, and of corrosive gases and liquids.
7.4 Ensure the warm-up time after power-on..
7.5 Warning: If the equipment is used in a manner not specified by
this instruction the perfection provided by the equipment may be impaired
7.6 Gentle handling in daily using, with dry and clean cotton cloth
cleaning.
