1. Overview
Manufactured and well-designed by G&G , adopting industial-class high precision sensors, measurement
circuit, dedicated MPU system, and controlling system, TC-H series electronic balances are high-quality
electronic weighing apparatus. Advanced technology, well-selected, exquisite processing and strict testing
make TC-H series of electronic balances be possession of following strong points:
1.1 High precision, hypersensitivity and fast reaction speed
1.2 High quality, strong anti-interference capability, long life, long-term using stability, adapting to the
adverse environment and long hours continuous work
1.3 With auto calibration, counting, total weight with tare, unit change
1.4 Balance is targeting output data interface and can be connected directly to the printer and computer to
collect and analyze the data. Balance can even remote controlled by computer
1.5 With large green LED display, easily legible.
1.6 The electronic weighting balances are targeted with data output function. Thus the balance can connect
with printer to print the data out. Or connects with computer to collect and calculate data. Meanwhile
computer can also remote control the balance, when it connects with balance.
1.7 Large-capacity rechargeable battery. One single charge can work for more than 36 hours. Balance can be
used during charging battery, which will not affect the functions of balance.

3. Preparatory work and attentions
3.1 Using environment: indoor, max. Altitude: 2000m, temperature: 0-40℃, humidity ≤80%,
Power fluctuations less than ±10%.
3.2 The scale should avoid sharp temperature changing, intense air flowing and ground
vibration. And keep the scale away from heat and humidity
3.3 Place the balance on the flat and solid table. Adjust the four legs to support the balance.
3.4 Use separate power outlet and avoid dynamic power.
3.5 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.
3.6 15min. preheating is needed.
3.7 When the indicator of battery lights, which means battery is near empty and needs to
recharge. Using balance under this situation can result in an instability or major error. At the
same time, the backlighting and calibration will automatically shut down.
3.8 Because of long-term not using, the scale must be placed in dry-ventilated place and
recharge every three months. Charging is necessary before or during re-using.
3.9 Warning：If the equipment is used in a manner not specified by this instruction the
profection provided by the equipment may be impaired
3.10 Gentle handling in daily using, with dry and clean cotton cloth cleaning.
4Operational Method
1.“” open key :Please put the balance on stable plane ,then turn on the power and adjust
level. Open the switch. The displaying windows displays from “Voltage、range ”、then
displays“F----1”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. Shutdown key also click this button.
2. “TARE”zero key:With empty scale platform, the displaying deviates from zero, pressing
“TARE” key, then the displaying will return to zero. For removal of the weight of
packaging materials, first stage please place the packing containers on the pan, after
stabilization press “TARE”, it shows 0. Then put the items into the container. At this point it
shows the net weight of the items. Take off the container and items, it shows the minus
value of the packing container. Press “TARE”again, it goes to 0.
3.“CAL”Calibration key: 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 displays “CXXX” and the

balance will automatic calibrate (XXX should be the weight of standard weights. For
instance, “C---20”indicates to put 20 kg test weights). At the same time, only place
calibrating weights on the scale platform. After stabilizing, the scale displays the weight of
the calibrating weights and the symbol “kg”; till now the calibration is completed 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.
4. “ ”compound key:The main function for conversion ,counting and print.Default
setting is the conversion.
4.1 convert units: Press“ ”, the units will be changed between “g”and “lb”. The indicator
will lighten.
4.2 Count
i. Choose samples. To precisely count the articles, 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.
ii. 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
indicates that balance is now counting. And all the samples are one unit. Then
press “kg/lb”, 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.
Note:For counting keys and convert the unit key, print for the same key buttons " " ,so
in the use of counting functions must first to balance setting, please refer to the setting
method of section 6 5 points.
4.3 Print : put the balance connect printer, Press" " ,the balance set A data,the printer
print.
5. Displaying Information
5.1 Display window
F----1 data beyond scope
F----2 AC/DC conversions
F----3 buttons
F----5 sensor faults
F----L lower zero position of sensor signal
F----H overload
C----F calibration error, instability or not at zero point during calibrating

C----H calibration error, items on the pan or at higher zero point during calibrating
E------ Storage calibration data error, re-calibration is necessary
5.2 Indicator
kg(g) lightening with stable data, the weighting units is kg or
lb lightening with stable data, the weighting units is lbr
pcs lightening with stable data, and counting situation
Lower voltage lightening in lower voltage with warning. Charge is needed, otherwise can
only last 1—2 hours. Balance is still working during charging.
Charge lightening during charging. One single charging needs 8 hours
Full charge slowly lightening at beginning of charging, and turning off after full
charging
6. Settings
Start the unit by holding down the “CAL”key till it comes to “F----3” and you are in the setting mode.
And pressing “CAL”can change the parameters; pressing “TARE”can change the values of parameters.
6.1 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
6.2 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
6.3 C3------Baud rate setting 2(600) 3(1200) 4(2400) 5(4800) 6(9600) . Default setting is 2
6.4 C4------communication setting. “TARE”changes the lower unit. “COUNT”changes the higher
units. This data is the first data during communication. Default setting is 27.
6.5 C5------units change. 0 is for units changing ,1 for printing ,2 for count .Default setting is 0.
Re-press “CAL”after setting. Then the balance is auto calibrated to 0.
Start the unit by holding down the “TARE” key till it comes to “F----3”. All the parameters can be
reset to default settings. Re-calibration before using
