1. Overview
Manufactured and well-designed by G&G GmbH, 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 witht are, 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 com-
puter 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.
2. Specifications and Performance indexes

3. Preparatory work and attentions
3.1 Using environment: indoor, max. Altitude: 2000m, temperature:
0-40℃, humidity 80%, Power fluctuations lessthan ±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 fourlegs 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
begently 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 with outpower 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.
4. Operational Method
4.1 The newly bought or long-time not used balances should be conn-
ected with power supplier before using. In order to charge the battery. Turn
on the power. Open the switch. The displaying windows displays from
“F----1” to “F----9” and after a certain time for stabilizing, “0” appears;
Then preheats for 15 minutes.
4.2 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.
4.3 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
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 calib-
rating weight sand 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” points table; and re-pressthe “CAL” to carry out calibration.
4.4 Count
4.4.1 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.
4.4.2 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.
4.5 Unit Change
Press “kg/lb”, the units will be changed between “kg” and “lb”. The
indicator will lighten.

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 par-
ameters; 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)
7(1200). 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 com-
munication. Default setting is 27.
6.5 C5------ units change. 0 is for units changing and 1 for printing.
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

Meaning of crossed–out wheeled dustbin:
Do not dispose of electrical appliances as unsorted municipal waste,
use separate collection facilities.
Contact you local government for information regarding the collection
systems available.
If electrical appliances are disposed of in landfills or dumps, hazardous
substances can leak into the groundwater and get into the food chain, dam-
aging your health and well-being.
When replacing old appliances with new ones, the retailer is legally
obligated to take back your old appliance for disposals at least free of charge.
