2Overview
The electronic balance PLC is a light, rugged precision balance suitable for different purposes. The
removable stainless steel pan allows the laboratory balance to be cleaned easily. The calibration of this
precision balance is done by means of external calibration weights (automatic calibration procedure).The
precision balance is equipped with four adjustable feet. If the balance is used in a laboratory, it can be
powered by the external mains adapter (included). In case the balance is used as a mobile weighing
instrument, it can be powered by AA batteries (not included).
Description:
designed for professional indoor or outdoor weighing.
High precision, sensitivity and rapid response time (<5 sec.).
DMS technology and therefore is also suitable for weighing of iron, nickel or other magnetic materials.
High quality materials and an optimized power supply.
High reliability and long service life.
An easy-cleaning, durable and stable shell [with wind protection]. (see chap. “Scope of delivery”)
Removable stainless steel weighing pan on a plastic support.
Four adjustable feet, a Level Indicator.
External calibration, zeroing searches, counting function, tare function.
Different measuring units can be selected via the keypad (g, ct, ozt, oz, GN, dwt, lb).
Large LCD display with backlight, digit height 15 mm.
Powered by the external mains adapter or battery (accumulator).
2.1 Proper Use
The balance you purchased is intended to determine the weighing value of material to be weighed. It is
intended to be used as a “non-automatic” balance, i.e. the material to be weighed is manually and
carefully placed in the center of the weighing plate. As soon as a stable weighing value is reached the
weighing value can be read.
2.2 Improper Use
Do not use the balance for dynamic weighing. In the event that small quantities are removed or added
to the material to be weighed, incorrect weighing results can be displayed due to the “stability
compensation” in the balance. (Example: Slowly draining fluids from a container on the balance.)
Do not leave permanent load on the weighing plate. This may damage the measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the balance, minus a possibly
existing tare load, must be strictly avoided. Balance may be damage by this.
Never operate the balance in explosive environment. The balance is not explosion protected.
The structure of the balance can not be modified. This may lead to incorrect weighing results, safety-
related faults and destruction of the balance.
The balance may only be used according to the described conditions. Other areas of use must be
released by G&G in document.
2.3 Control of inspection, measuring and test equipment
As part of quality assurance the measuring-related properties of the balance and the available adjusting
weight must be checked regularly. The responsible user must define a suitable interval as well as the

6Unpacking, Setup and Commissioning
6.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing results are achieved in common conditions of
use. You will work accurately and fast, if you select the right location for your balance.
Therefore, observe the following for the installation site:
Major display deviations (incorrect weighing results) may be experienced should electro-
magnetic fields (e.g. due to mobile phones or radio equipment), static electricity accumulations
or instable power supply occur. Change location or remove source of interference.
Place the balance on a firm, level surface;
Avoid extreme heat as well as temperature fluctuation caused by installing next to a radiator or in the
direct sunlight;
Protect the balance against direct draughts due to open windows and doors;
Avoid jarring during weighing;
Protect the balance against high humidity, vapors and dust;
Do not expose the device to extreme dampness for longer periods of time.
Non-permitted condensation (condensation of air humidity on the appliance) may occur if a cold
appliance is taken to a considerably warmer environment. In this case, acclimatize the disconnected
appliance for ca. 2 hours at room temperature.
Avoid static charge of goods to be weighed or weighing container.
6.2 Unpacking / Installation

Operating Instructions
6.3 General power supply
If the balance is used in a laboratory, it can be powered by the external mains adapter (included). In case
the balance is used as a mobile weighing instrument, it can be powered by AA batteries (not included) or
internal accumulator (included). The accumulator is charged via the delivered adapter.
To extant work time of accumulators (battery), it is possible to turn off display’s backlight and the balance
automatically. The settings of “Power Save” operation see chap. 9.3 and chap. 11.
Please only use the original supplied mains adapter. Otherwise there is a risk that the Balance be
impaired.
If the balance is not used for a long time, remove the battery/accumulator and store them separately.
Leaking battery liquid could damage the balance.
6.3.1 Battery power supply
The balances can be supply from mains power witch is delivered with the balance. It is also possible to use
normal AA batteries.
6.3.2 Mains connection during rechargeable battery operation
When the balance is connected with the mains adapter, the battery power will be disconnected
automatically. Therefore, there is no battery charging function under the battery power supply.
6.3.3 Battery exchange
Remove the battery compartment cover and insert six batteries (AA size) into the battery compartment,
taking extreme care that the polarities plus (+) and minus (-) is observed.
6.4 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have reached the
operating temperature (warming up time 30 min.). During this warming up time the balance must be
connected to the power supply (mains, accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Please read the information carefully in chap. “Adjustment”.
6.5 Adjustment
As the acceleration value due to gravity is not the same at every location on earth, each balance must be
coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration

G&G GmbH | Unpacking, Setup and Commissioning
11
due to gravity at its place of location (only if the balance has not already been adjusted to the location in
the factory). This adjustment process must be carried out for the first commissioning, after each change of
location as well as in case of fluctuating environment temperature. To receive accurate measuring values it
is also recommended to adjust the balance periodically in weighing operation.
6.6 External calibration
Adjustment with recommended adjustment weight (default setting) Weight value of the required
adjustment weight sees chap. 1 “Technical data”. Weights of different nominal values may be used for
adjustment but are not optimal for technical measuring. Info about adjustment weights can be found on
the Internet at: www.gandg.de
Operations sequence:
Observe stable environmental conditions. A warming up time (30 min.) is required for stabilization.
Press the [ON/OFF]-Key, turn on the balance.
Then press the [CAL]-Key, keep it pressed until the acoustic signal gets mute and the weighed value “C
XXX” for the required adjustment weight appears flashing. (e.g.: C 100 means 100 g)
During the flashing display put the required adjustment weight carefully in the center of the weighing
plate.
The flashing display disappears.
After successful adjustment the balance automatically returns to weighing mode.
Take away the adjustment weight, the display shows ZERO.
If an error message “C----F” is displayed in the event of an adjustment error or incorrect adjustment
weight. Wait until the balance is again in weighing mode and repeat the adjustment procedure.

9Basic Operation
After new purchase of the balance or after a long storage, you have to calibrate the balance before the first
commissioning. Level the balance with the adjustable feet horizontal until the air bubble in the level is in
the center of the Level Indicator. Give the balance after changing the location a warm-up time min. 30 min.
before using. This time is necessary for the balance to adapt to the eventual temperature.
9.1 ON/OFF - [Power On/OFF]
Press the [ON/OFF] button to turn on the balance. The display shows the message "ON". Then the max.
weighing range is displayed. The balance will carry out a self-test (F----1 to F----9). When the "0.00g" in
display appears, the balance is ready for operation.
Press the [ON/OFF] button and keep it pressed, until the display shows the message “OFF”. The balance
will switch off then.
9.2 TARE
When the pan is empty and indication is different than zero press [TARE] key.

G&G GmbH | Basic Operation
15
Weighting with tare: place the weighing box and press the [TARE] button. After standstill control the zero
display appears. The weight of the container is now internally saved. Weigh the material, the net weight
will be indicated. The weight of the weighing container will be displayed as a minus number after removing
the weighing container. The tare weight is saved until it is deleted. Remove the load from the balance and
press the [TARE] button. The tare procedure can be repeated as many times as necessary, for example
with initial weighing of several components for a mix (add-on weighing). The limit is reached when the
total weighing range capacity is full.
9.3 LIGHT - [Display backlight]
Press the [LIGHT] key to change the display’s backlight mode.
[b ON] - Background illumination on. Display rich of contrast which can also be read in the darkness.
[b OFF] - Backlight switched off to save battery.
[b AUTO] - This display will appear backlit for weight value is not stable. When the weight value is stable,
the display will be extinguished 3 seconds later.
9.4 COUNT - [Pieces counting function]
Before the balance can count parts, it must know the average part weight (i.e. reference). Proceed by
putting on a certain number of the parts to be counted. The balance determines the total weight and
divides it by the number of parts, the so-called reference quantity (1, 10, 20, 50, or 100). Counting is then
carried out on the basis of the calculated average piece weight.
As a rule: The higher the reference quantity the higher the counting exactness.
Follow these steps:
a) Press [COUNT]-key to change the balance into counting mode.
b) Place as many pieces to add-up as required by the reference quantity. Press the [UNIT] button to enter
the setting menu. The display now shows the number "1" and the unit "Pcs".
c) Using the [UNIT] button select the reference quantity (1, 10, 20, 50, or 100).
d) After successful reference determination the current quantity is displayed and the unit “Pcs”.
e) Remove reference weight. The balance is now in parts counting mode counting all units on the
weighing plate.
9.5 UNIT- [Weighing unit selection]
Use the [UNIT]-key to choose weighing units: g (gram), ct (carat), ozt (troy ounce), oz (ounce), GN (gran),
dwt (pennyweight) and lb (pound).

11 Configuration & User Menu
The settings of the balance can be changed in the setting menu. This way, the balance can be adjusted to
individual weighing requirements. By the factory the user menu has been set in a way that normally no
more changes must be made, only at special conditions of use.
Overview:
In the off state press the [CAL] button and keep it pressed, press the [ON/OFF] button turn on the balance.
Now the balance is accessed to the setting menu. Using the [CAL] button the individual menu items (C1-
C3) can be selected one after the other. Press the [TARE] button to change the setting value. After all
points have been configured, press [CAL] button returns the balance automatically into weighing mode.
a) C1 = sensitivity setting - values: 0 1 2 3 4
The higher the value, the lower the sensitivity and higher stability.
Filter 0: Setting for dispensing.
Filter 1/2: Sensitive and fast, very quiet using location.
Filter 3/4: Robust but slow, busy using location.
Default setting is 2 or 1.
b) C2 = filtering strength setting - values: 0 1 2 3
The higher the value, the lower the sensitivity and higher stability.
Filter 0: Setting for dispensing.
Filter 1/2: Sensitive and fast, very quiet using location.
Filter 3: Robust but slow, busy using location.
Default setting is 2 or 1.
c) C3 = serial port setting - transmission speed (RS-232)
2(600), 3(1200), 4(2400), 5(4800), 6(9600) - Default setting is 6.

d) C4 = device number / communication setting (RS-232)
Press [TARE] button changes the value smaller. Press [COUNT] button changes the value bigger. The
number corresponds to the first data signal to the command control of the computer.
Default setting is 27 (1Bhex).
e) C5 = Autom. Abschaltung - values: 0 1 2 3 4 (*only valid for Battery- / Accumulator power supply)
0: disabled
1: after 15 min.
2: after 30 min.
3: after 45 min.
4: after 60 min.
Default setting is 2 or 1.
f) C6 = setting of Print-Key for balance
0 (no print-key), 1 (use [UNIT] as print-key), 2 (use [COUNT] as print-key) - Default setting is 0.
g) C7 = Backside Display Off (*only valid for PLC-300-C, PLC-600-C, PLC-1200-C, PLC-100B-C and PLC-
200B-C)
0 = Backside Display is disabled.
1 = Front- and backside Displays are enable.
Default setting is 1.
h) Save settings
After all points have been configured, press [CAL] button returns the balance automatically into
weighing mode.
i) Restore the factory settings
In the off state press the [TARE]button and press the [ON/OFF]button turn on the balance, keep the
[TARE] button pressed until the balance returns automatically into weighing mode. All the parameters
will be reset to default settings. Please re-calibration the balance before using.
