UNPACKING THE BALANCE AND GETTING STARTED
1. Carefully remove the scale, pan, and all of its components out of the packaging and place them on a stable
base where the scale will not be affected by any mechanical vibrations or air movements.
2. After removing the chamber base (4), draft ring (3), pan base (2), and the pan (1) from their packaging,
carefully install the chamber base (4) on the case of the balance as shown below. Once the chamber base is in
place, install the draft ring (3). Once components 4 and 3 are in place install the pan base onto the scale by
placing it on the pan support located in the middle of the scale. Once the pan base has been installed, carefully
place the pan on the base as shown below.
8
Page 9
Instruction Manual - TORBAL AGCN Series
3. Once the pan has been installed, level the scale by adjusting the rear feet until the level indicator shows the
“air bubble” is in the center position of the sight glass. The level indicator is located in the rear left side of the
scale.
4. After leveling the scale, you may plug the AC adaptor to the AC adaptor socket located in the rear of the scale.
5. When the AC adapter is plugged into the wall outlet, the scale will turn “ON” automatically, initialize itself,
perform automatic internal calibration and enter weighing mode.
6. To put the scale into standby mode, leave the AC adaptor plugged into both the scale and the wall outlet and
press the Power “OFF” button ( ). The “OFF” indicator will light up in the upper left corner of the
display signaling the scale is in standby mode.

WEIGHING
1. To begin weighing, press the power button ( ) to turn the scale ON. The scale will go through its
initialization procedure and automatically enter Weighing Mode. The scale is ready to begin weighing as soon
as the stabilization ( ) indicator appears on the display.
2. When weighing, always place the mass in the middle of the pan. The weighed result may be taken when the
stabilization indicator appears on the display.
7.1.1.Taring
1. If a container is used for weighing, it may be tared. In taring the container, the scale subtracts the weight of the
container from the gross weight to obtain the net weight.
2. To tare the weighing container, place it in the middle of the pan. The container’s weight will be shown on the
display.
10
Page 11
Instruction Manual - TORBAL AGCN Series
3. Once the stabilization indicator appears on the display, the container is ready to be tared. To tare the container,
press the “T” button. The display will show a dotted line which indicates the scale has begun the taring
process,
4. When finished taring, the balance will return to Weighing Mode. The display will indicate 0.0000, and the
NET indicator will be shown on the display signaling the next weight taken is a NET result.
7.1.2.Clearing a Tare
1. To clear the tare, remove the tared object along with the NET weight from the pan. The scale will then display
a negative NET tare result.
2. To clear the tare, press the T button.
3. The display will show dashed lines indicating the tare is clearing.
4. When finished clearing the tare, the scale will return to Weighing Mode.

m 2 – mass calculation in liquid
To calculate density in liquid the following formula is used:
m 1 – mass of the plunger in air
m 2 – mass of the plunger in liquid
V – Volume of the plunger
