CHAPTER 2 SCALE PREPARE
1. Prepare:

a. Wired
Single Scale (Typical: Weighbridge): Connect your scale to the indicator Channel A OR
Channel B.
Double Scale (Typical: Axle Scale): Connect your scale to the indicator Channel A AND
Channel B.
Multiple Scale (Typical: Wheel Scale):
Connect your scale to the indicator Channel 1# and Channel 2# for the 1st axle,
Channel 3# and Channel 4# for the 2nd axle, … Channel 15# and Channel 16# for the 8th
axle.
Combined Scale (Typical: Multi Decks Combined Weighbridge):
Connect 1st Deck to Channel 1#, 2nd Deck to Channel 2#, 3rd Dec to Channel 3#.
Please note the indicator has 4 pins male connectors as default.
b. Wireless
No need to connect any cable. Switch on wireless scale first then indicator. They will setup
connection automatically.
2. Portable Scales Check
a. For portable scales, usually for portable axle scale or wheel scale, please make
below preparation:

b. Choose a flat area to place the portable scales. Make sure the scales stand on
ground without seesawing.
c. Make sure the ground is clear and without small chippings.
d. Make sure the scale is towards the vehicle wheels center.
e. Make sure the distance between two scales is suitable and wheels will not
move out of the scales.
f. For wireless scales, make sure the antenna towards to the indicator.
3. Switch on
a. For Wired scales, switch on indicator.
b. For Wireless scales, switch on scales first. Scales will start to look for
indicator connection immediately.
Put Magnet Switch Key
to the Switch Hole for 5 seconds.
When the
indicating light start to
flash, it is ON.
c. Please switch on the indicator within 1 minutes after scales are on to setup the
connection. If the connection cannot be established, the scales will
automatically switch off. When indicator is switched off after work, the
wireless scales will automatically switch off.
CHAPTER 3 SYSTEM OPERATION

1. System a. Switch On
Press the “Power” button on indicator first to start power supply. Please note the indicator
should be charged or connected to the AC power supply.
The indicator will start self-checking process, and this will take up to 10 seconds.

“Department” There are 3 lines to enter the using department information including company
name, company address, contact number, etc. The information will be printed in the
weighing ticket.
Please note: Each line accepts maximum 128 alphabets.
“Operator” Enter the name of operator.
“Manual” It is set the system to Manual In-Motion Weighing
“Auto” It is set the system to Auto In-Motion (Unmanned) Weighing (see next page)
“Speed” It is selecting the speed unit - “km/h” or “mph”.
“Print Mode” Selecting whether ticket will be printed after weighing process completed
“Auto” Means the ticket will be printed automatically after weighing.
“Manual” Means the ticket will NOT be printed.
“Copy” It is to select tickets quantity each time prints.
“Location” There are 3 lines to enter the location of the weighing process. The information
will be printed in the weighing ticket.
Please note: Each line accepts maximum 128 alphabets.
When “Auto” weighing mode is selected, there is an extra option of whether the unmanned
system will be working.

Default is 10 seconds. In “Dynamic Weighing” the countdown timer will be available.
In “System Setting”, brightness of the screen, date, time screen saver time, can be adjusted.
3. Weighing Setting (II)
When click on “Weighing Setting”, the system will ask for password.
It is the “Auto En
d” option.
When this is ON, the countdown timing can be changed.

The default password for this is “878586” and in case you changed it, please write down and
keep the password at a safe place.
Please note: Everywhere require Class II level password will be the same. If you have ever
changed this password, you will need to use new password for other places where require
Class II level password.
The (II) stands for password level. In the system there are three levels password.
“I” or No Marking stands for level 1 password. This password is stored plaintext in the
system. Typical for this is the user password. It is stored in the system and in case it is lost,
the Administrator could be able to change it.
“II” stands for level 2 password. This password is stored by normal encryption algorithm in
the system. If it is lost, our factory could use our own tool to read the password by connecting
to the indicator. Default password is 878586
“III” stands for level 3 password. This password is stored in chip by SHA-256 encryption
algorithm. This is unchangeable because there is no way to recover it. However, we could
customize this password for different distributors. Default password is 549717.

4. Enter main menu of Weighing Setting
Caution: All options here are related with kernel computing and any Unauthorized
Change may result in Losing Warranty.
“Axle Config Optimize” This is the key algorithm of our system for different axles. This data
comes from our analysis to over 12,000 vehicles. Default would suggest switching it on
when the indicator is connected for in-motion weighing purpose. It is not recommended to
change this unless it is authorized by the manufacturer.
“Optimize the speed” This is the key algorithm of our system for different speed. This data
comes from our analysis to over 12,000 vehicles. Default would suggest switching it on
when the indicator is connected for in-motion weighing purpose. It is not recommended to
change this unless it is authorized by the manufacturer.

This is to make the upgrade of the system.
Please note: Please use the firmware offered by the manufacturer
only. Unauthorized Firmware will result in Losing Warranty.
This is the algorithm for AUTO In-Motion Weighing (Unmanned). This data comes from
our analysis to over 12,000 vehicles. Default would suggest switching it on when the
indicator is connected for in-motion weighing purpose. It is not recommended to change this
unless it is authorized by the manufacturer.
This is option to load default ex-factory settings and data. This is
the final step for rescue the system. Usually, it is not recommended
to offer the end user this service manual because any untrained
operation may affect the accuracy and get system into endless loop. But in case anything has
been changed due to error operation, click on this button to drop all customized setting and
load default setting may rescue the system. If this doesn’t work, the indicator has to be
returned to the manufacturer for maintenance.
5. Scale (III)
This is settings to connect the indicator to the scales.

This is to select the Channels which is going to work. For two channels
system, there are Channel A and Channel B for option. If only 1 channel is
selected, the wire must be connected to the Selected Channel Port. Typical
Application for one channel is getting the total weight from a weighbridge. In some cases,
customer will use one weighing scale to weigh one side of the vehicle and make the result
multiply by 2. This will get a roughly total weight of a vehicle, but the accuracy could be up
to 20%. Typical Application for 2 Channels is the axle weighing scale or wheel scale.
This is to be selected Wired or Wireless.
When this is ON, it is used for big
weighing capability from 0.5t – 600t. And unit for below weighing capability setting will be
Ton or Kilo lbs.
When this is OFF, it is used for normal weighing capability from 0.5kg – 50,000kg. And unit
for below weighing capability setting will be KG or lbs.
This is to set the single scale capability,
even the system is connected to multiple
scales.
This is the minimum weight for the system to record down.
Maximum value of this limit is 10% of the maximum single
scale capability. And Minimum value is 0.1 unit. But when
the value is lower, the readability and stability of the scale are going to be less.
This is to switch unit of weights. It can be selected from: Kilo Gram,
lbs, Ton or Kilo lbs.
Please note: When unit is changed, the system will drop all calibration
data and full scale will need to be re-calibrated.
CHAPTER 4 CALIBRATION

1. Calibration'(II)'
When click on Calibration (II) on main menu, you will need to enter password, the
default password is 878586. However, the Admin can change it after calibration and once
the password is changed, there is no way to recover. So, please keep the new password
at a safe place.
2. Check'the'details:'

Please&confirm&the&unit&and&select&the&division&as
&your&demand&before&calibration.&
3. Although'two'channels'are'connected,'only'ONE

4. Calibrate'Zero'Point'first.'Make'sure'there'is
'nothing'left'on'the'scale.'
'
If only 2 points calibration is executed, the system will automatically record the loading.
If multi-point calibrated, the system would have linear compensation.
The loading point must be input before loading the weights on scale.
During calibration, the procedure could be always re-start again by clicking on “Restart
from ZERO”.
