PRECAUTIONS FOR USE
Thank you for purchasing BH3 precision balance.
To enable you to use this balance correctly, we suggest that you read these precautions carefully.
1. It must be prevented from getting wet. If it gets wet, please wipe it dry with a cloth. If there
is something wrong with the machine, please contact your supplier.
2. Keep it away from high temperatures and damp conditions.
3. Don’t bump the balance against other items, nor load it with excessively heavy weights (The
load must not exceed the maximum capacity of the balance).
4. If a balance is not used for a long period of time, please remove the dry batteries, clean and
store in a polythene bag. A desiccant may be included.
5. Objects to be weighed should be placed at the center of the platter, and can’t exceed the
dimension of the platter.
6. Any opinions and suggestions on this product are welcome.
PREPARING TO USE THE BALANCE
1. For accurate weight readings locate the scale on a firm level surface free from vibrations.
2. Avoid operating the scale in direct sunlight or drafts of any kind.
3. Remove any weight that might be on the weigh pan before the scale is switched on and avoid
leaving weight on the pan for long periods of time.
4. Please use an independent power outlet to avoid interfered by other electrical appliances.
5. Don’t put any object on the scale while switching on the balance.
6. Please keep the balance switched on for 15~20 minutes before operation.
7. When the low battery indicator appears in the right corner of the display, replace the
dry batteries or recharge the battery.
8. The balance will work with either dry batteries or the adaptor. When the balance is out of
battery with its adaptor unplugged, time will need to be reset. Please replace the battery
before proceeding to reset the time.

CHAPTER TWO OPERATION INSTRUCTIONS
2-1 Zero Function
When the display shows weight value without anything placed on the platter, press the key
to re-zero the balance. The zero indicator 0is on, indicating a center-of zero gross weight
condition.
Note: Zero Range
Non-approval and OIML approval models: Zero-point deviation* is within 2% x full scale
Sri Lanka approval models: Zero-point deviation* is within 3% x full scale
*Deviation is based on the power-on zero point.
2-2 Simple External Calibration
Press the key for 3 seconds, the calibration weight value** shows in the display. Place
the same weight as the calibration weight value on the platter. After stable, the calibration
procedure is completed.
Calibration weight value** = The value was input in the external weight calibration setting.
(Please refer to page 27)
2-3 Operation Mode Conversion
Press the key to convert among the available operation modes: Weighing Mode, Counting
Mode and Percentage Mode. When selecting a different operation mode, the representative unit
or symbol (g, pcs and %) will show in the right side of display.

Ⅰ. Units Selection
Press the key to select the desired weighing unit.
There are 13 units available: g, ct, lb, oz, dr, GN, ozt, dwt, MM, tl.J, tl.T, tl.H and t.
Ⅱ. Display Mode/Resolution Selection
Non-approval models: Press the key to shift between Display Unit Weight Mode and
Display pcs Mode.
Approval models: Press the key to shift weighing resolution between normal resolution and
high resolution.
Ⅲ. Tare Function
1. Place the container on the platter. After stable, press the
T
key to deduct the container
weight. The display returns to zero and the tare indicator
T
is on.
2. Place the object into the container, and the net weight of the object is displayed.
3. Remove the container and the object from the platter, and the negative value of the container
weight is displayed. Press the
T
key again to re-zero and the tare indicator is off.
The balance can be tared continuously up to its full capacity.
If the tare indicator
T
is still on, after pressing the
T
key to exit the tare mode.
Please press the key to zero the balance, and the tare indicator
T
will go off.
For Sri Lanka approval model(s), you can only tare once.

Sampling
1. Press the key to select the Counting mode and the display shows pcs.
2. Press the key to select a sample size from 10, 20, 50, 100, or 200 pcs.
3. Place as many items as the selected sample size, and press the key. After the sign

count.
4. Press the / key to shift between “Unit Weight Mode Display”and “PCS Mode
Display”.
The unit weight of sample is not sufficient: The weight of a sample should be heavier than
the 0.2d (d=division). When the unit weight of the sample is too small (less than 0.2
divisions), “pcs” is displayed.
The last sample size is memorized when the balance is switched off. When the balance is
switched on again, press the
PCS
key to enter the counting mode.
If “Auto Unit Weight Averaging”setting is enabled, the scale will recalculate average unit
weight when current sample count (of current objects on the platter) exceeds previous
sample count by more than 5 pcs and is less than 200% of previous sample count, i.e.
(p + 5) < (c) < (200% x p)
