BEFORE USING THE SCALE
Thank you for purchasing High Precision Electronic Counting Scale. In order to use the scale
properly, please read this User Manual carefully before use. If you have any problem with scale,
please contact your supplier.
INSTRUCTION FOR USE
1) Please keep the scale in a cool dry place. Do not store it at high temperature.
2) Do not allow any liquids to come into contact with the scale. If necessary wipe the scale with a
dry soft cloth.
3) Avoid objects impacting with the scale. Do not drop loads onto the scale or subject the weighing
pan to any strong shock loads.
4) The load placed on the weigh pan must not exceed the maximum weighing capacity of the
scale.
5) If the scale is not going to be used for some time, please clean it and store it in a plastic bag in
dry conditions. A desiccant sachet may be included to prevent any moisture build up.
PREPARING TO USE THE SCALE
1. Locate the scale on a firm level surface free from vibrations for accurate weight readings.
2. Adjust the four leveling feet (if fitted) to set the scale pan level using the spirit level bubble
located at the front of the scale.
3. Avoid operating the scale in direct sunlight or drafts of any kind.
4. If possible avoid connecting the scale to ac power outlet sockets which are adjacent to other
appliances to minimize the possibility of interference affecting the performance of the scale.
5. 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
6. All goods weighed should be placed in the center of the weigh pan for accurate weighing. The
overall dimensions of the goods being weighed should not exceed the dimension of the
weigh pan.
7. Once the scale has been powered on, it will go through an LCD display test and it is ready for
use when the display shows zero.
8. The scale requires 15~20 minutes warm up before operation to ensure best accuracy.

9. Please note when the display shows ( ------ BAT LO ) , it’s means the battery need to be
charged.

3 [INSUFFICIENT UNIT WEIGHT] : The sample weight should be heavier then the minimum
capacity of the scale(20d), otherwise the arrow pointing to the insufficient unit weight symbol
will be on
4 [INSUFFICIENT SAMPLING] : The weight of a sample should be heavier than 1d
(d=division), otherwise the arrow pointing to the insufficient sampling symbol will be on

1.4 OPERATING THE SCALE
1.4.1 Power On
1.1) After switch on the scale, LCD Shows C 0 1 v 1.05 6000
1.2) Auto count down: From 999999 999999 999999 ~ 000000 000000 000000
1.3) After return to zero and being stable, scale will enter into counting mode
Weighing：
2.1) Let the scale return to zero and stable
2.2) Place the object on weighing pan and wait the scale stable; to read the actual weight value of
the object

2.3) The max. weighing range of the scale is - The max. weighing range of the scale plus 9d, if the
object on the pan is over then the max. weighing range, the display shows as ff. then the beeper
sounds, please remove the object to be able to continue operate the scale
1.4.2 Zeroing the Display
When the weigh pan is empty (free of load) and the display is not showing zero (Slight variation
happens in weight window), press the ZERO key to zero the scale.，At zero, the zero indication is
on
1.4.3 Manual Tare Operation
Place the container on the weighing pan (ex. 305g), then press TARE key then the tare indicator
is on

1.4.6 Sampling, Calculating Average Piece Weight (APW)
1.4.6.1 Place the desired sample onto the weighing pan. Enter the sample size (ex. 20) via
the numeric keypad then press SMPL key
1.4.6.2 After scale becomes stable (SMPL indicator on)
1.4.6.3 Place again various same objects (the quantity should lesser than first time), the scale will
auto-sampling (calculate the more accurate piece weight) then the scale becomes stable
Note: The scale has auto-sampling function, when the objects’ weight is lesser than last time and
the average weight is in the tolerance, the software will auto-count the average weight again, this
function helps lessen the inaccuracy in counting the quantity, but if the auto-sampling function is
disable, the scale will not auto-sampling

2.1 C101_Calibration
A. Setting up division, decimal point, max. capacity and calibration
Press and hold “M+/MR” key，then turn on the scale，to enter division setting: In
kg for the calibration unit, do not accept other units)
1. Division Setting： (unit is in kg)
LCD shows [ ? ] [ d] [ SEt] then press “ZERO” key to select 1、2、5、10，and then press
“M+/MR” key to confirm，and enter the decimal point setting.
Ex. When display shows [ 1] [ d] [ SEt]，Press “M+/MR” key，the division set as 1，then enter
the decimal point setting.
2. Decimal point setting：
LCD shows [ ?] [ P] [ SEt] then press “ZERO” key to select 0、0.0、0.00、0.000、 0.0000，
0.00000，and then press “M+/MR” key to confirm，and enter the maximum capacity setting. Ex.
When display shows [ 0.0000 ] [ P] [ SEt]，Press “M+/MR” key， the division set as 0.0000， then
enter the maximum capacity setting.
3. Maximum capacity setting：
LCD shows [03.0000] [ FULL] [ SEt] According to the decimal point set, decimal point position has
been fixed. Direct press [ 0 - 9 ] key enter the correct Numbers (shift fill 0), and then press “M+/MR”
key to confirm，and enter the Zero point calibration.
Ex. LCD shows [03.0000] [ FULL] [ SEt] ，Press “M+/MR” key，the biggest weighing is set to 3
kg， then enter the Zero point calibration.
4. Zero point calibration：
LCD shows [ CAL 0 ] [ 0] [ 1234](The sensor zero code)
Do not put any objects on the pan when display shows this, then scale will move to next calibration
setting.
5. Second point calibration：(unit is in kg)
LCD shows [00.0000 ] [ 0] [ 1234] the decimal point was set as 4 digits. (this depends on what user
sets in the last moves). Directly placed weight on the scale and press [ 0 – 9 ] enter the required
number and weight weight values are equal, when stability symbols show, then press
