Safety
Always disconnect the vehicle battery while installing SkidWeigh system or any other electronic product.
Make sure that unit, pressure transducer and any other associated cables are securely mounted and do not impede
any of the vehicle’s controls. Use care when routing the components cables. Route the cables where they will be
protected. Use commonly accepted install practices for after market industrial vehicle electronic devices.
The installation of the SkidWeigh systems should only be performed by an acknowledged lift truck dealer technician
or end user technical installer familiar with material handling vehicles operation.
Here are two acceptable methods of making a wire connections:
* Soldering electrical connections (recommended)
* Crimp connectors (with the use of the proper crimping tool)
Regardless of the method you choose, ensure that the connection is mechanically sound and properly insulated. Use
high quality electrical tape and shrink tubing where necessary.
This product is connected directly to the vehicle’s ignition switch, 12 to 55 VDC. There is no on-off switch on the unit.
For vehicles with voltages higher than 55 VDC use voltage convertor ( 36 to 160 VDC, Part No. VC-160)

Overview of components
The standard ED2-2X series check weighing system consist of two main components:
* LED display digital indicator with external two position switch, mounting bracket and wiring harness cable
Turn switch for channel 1(Mode 8) and channel 2 (Mode 82) shown on LED display
* Hydraulic pressure transducer with 3 wires cable
* Installation & calibration manual and operator usage instruction
SkidWeigh ED2-2X series operational principal
The ED2-2X SkidWeigh system operational principal is based on the hydraulic pressure transducer mounted in the
vehicle lifting hydraulic circuit between lift control valve and lifting cylinder(s). There is need for external switches,
proximity sensors or specific operational procedure of lifting the forks in order to obtain a proper load weight readout.
Integrated Visual Data Technology Inc., 3439 Whilabout Terrace, Oakville, Ontario, Canada L6L 0A7

SkidWeigh “weighing cycle” will be automatically activated every time load is lifted just above the ground. The
increase in pressure is converted in an electronic signal at the sample rate of 16000 readings per session which is
converted into a load weight reading utilizing proprietary software algorithm.
Pressure transducer installation
The pressure transducer must be installed in the lifting hydraulic line between the lift control valve and lift
cylinder(s). Mount a T-piece in hydraulic line. In some cases you can install the pressure transducer in the flow
divider, drilling and tapping for 1/4”-18 NPT male in spare plug (single or double mast configuration) or in the body of
the flow divider. In some cases you can drill and tap on “larger elbow” if available in the hydraulic lifting circuit found
in vehicles with larger hoses accommodating larger vehicle lifting capacities.
Pressure transducer installation precautions
Before installation of the pressure transducer the hydraulic lift circuit must be pressure free.
There are two ways to do that:
1. Place the forks on the ground in their lowest position and make the hydraulic system pressure free by tilting the
mast forward. The chain(s) should be slack.
2. Lift the forks and position them on the top of a supporting fixture. Start lowering the lifting cylinder into its lowest
position. Be sure that chain(s) are slack.
Make sure that that installed pressure transducer will not touch any moving parts or assembly of the vehicle while in
normal operation. Pressure transducer has 1/4”-18 NPT male thread. Use
thread seal to ensure tight fit.
Selecting the mounting location for digital indicator
Use the mounting flange and fasten digital indicator on the vehicle dashboard or
side railing preferably on the right hand side.There are many examples of
mounting locations that will depend on the vehicle model. However, additional
mounting items such as a flat brackets may be needed to help secure the unit to
upper right corner of the guard or side railing.
Choose the correct location and make sure that:
- Indicator is visible and within reach of the operator
- Location so that operator does not hit a head

“Quick test to determine if electrical connections are done right”
Note: This procedure is only to test if electrical connections of the system installation into the vehicle is
done properly!
After you have connected electrical power and pressure transducer cable you can “quickly” check the
system operation.
- Lower the forks to the ground (No hydraulic pressure in lifting cylinder)
- Turn on ignition switch or power on switch
- Digital LED display will show software version (Example 1600)
- Number 8 will be shown in Mode digit
- Lift forks with any load just above the ground. Mode number 8 will go off for few seconds and some load
weight will be shown on the LED display.
- If the above test is valid then the system electrical connections are done right. The next procedure will
be to calibrate the SkidWeigh weighing function.
Lift truck equipped with hydraulic accumulator
If the standard SkidWeigh system is installed on the lift trucks equipped with hydraulic accumulators,
please contact us to provide you with different digital indicator having specific software algorithm to
obtain load weight accuracy within +/-1% of vehicle maximum lifting capacity.
Weighing function calibration procedure
The SkidWeigh calibration is automatic and is done by lifting empty and loaded forks with known calibration load
weight just above the ground. MAKE SURE THAT YOU HAVE A KNOWN LOAD WEIGHT AND KEEP IT NEARBY
TO COMPLETE THE CALIBRATION.
For the best results use at least minimum calibration load test weight of 40 to 60% of maximum lifting capacity of
the lift truck. Use customer floor scale or find a known skid load weight within the operational facility.
-Use paper clip to access buttons “M” and “Arrow Up”

Important
If you want the system to show load weight in pounds, use the known calibration load weight
in pounds during the system calibration and enter that value accordingly. The same would
apply if you want the system to show load weight in kilograms then use the known calibration
load weight in kilograms and enter that value into the system accordingly.
Calibration starting point (Turn two position switch to Mode
8representing weighing channel 1)
Lower the empty forks to the ground. There should be no hydraulic
pressure in lift hydraulic circuit.
- Turn ignition switch to on position and start the engine
- LED display will show software version on the right side and number 8 will be
shown in Mode window.
Calibration of empty forks being lifted just above
the ground
To initiate calibration press the “M” button (use a paper clip) and hold
it down for approx. 5 seconds until Mode digit 8 changes to 0.
System is ready for automatic zeroing of the scale function
When LED display is showing “0” in Mode digit, lift the
empty forks just above the ground to automatically
calibrate zero value for empty forks being lifted.
Activate the lift control valve as you would do during
the normal lifting operation. Do not attempt to lift
the empty forks slowly.
After few seconds, LED display will show “1” in Mode digit and “0”
value in furthest right digit display.
(Instead of 0 value it could be any other number from 0 to 9, depending
on previous calibrated load weight entered into the system)
Automatic zeroing is done!
Note: Next step will be calibration of the system by lifting known load weight
Integrated Visual Data Technology Inc., 3439 Whilabout Terrace, Oakville, Ontario, Canada L6L 0A7

Calibration of loaded forks being lifted just
above the ground
Pick up a known load weight and lower it to the ground.
In our example we will use a known calibration load weight of
4000 pounds
* Button M is used to enter into weighing calibration procedure and shift to the next digit.
* Button Arrow Up is used to input digital value 0 to 9, wrap around.
Start entering a known load weight value for each digit by using arrow up button (increments
from 0 to 9 for each digit), wrap around. To move to next digit press “M” button.
- Start with least significant digit of the known calibration load weight. (In our case this is “0”)
- Use “M” button to increment to the next digit on LED display.
- Keep pressing “M” button and enter a third, forth and fifth calibration load weight value.
As the input for known load value has only four digits (4000 in our example), the fifth digits
must be “0”.

-Before going to Mode 6 make sure that the “Known load weight”
is ready to be lifted.
-The loaded forks must be on the ground.
(No hydraulic pressure in the lifting hydraulic circuit)
- Press the “M” button to advance to Mode 6 and immediately lift
the “Known load weight” just above the ground.
Note:
Activate the lift control valve as you would do during the normal
lifting operation. Do not attempt to lift the empty forks slowly.
- LED display will go blank and within few seconds LED display
will show the value of calibrated “Known load weight of 4000”
Lower the load to the ground.
System will go automatically into operational mode.
System is ready to be used.
Mode digit will display number 8.
Note: If system is set up for overload alert the Mode 7 will be shown automatically. Follow instruction for
overload warning alert value input.
Weighing calibration function for weighing channel 1 is done
Lower loaded forks to the ground.
Turn two position switch to Mode 82 representing weighing channel 2and complete same calibration
Integrated Visual Data Technology Inc., 3439 Whilabout Terrace, Oakville, Ontario, Canada L6L 0A7

Overload Alert Value Input (Optional for both channels)
As soon SkidWeigh system weighing function calibration is done the loaded forks must be
lowered to ground.
The Mode 7 digit automatically will be shown and will remain on LED display until overload alert
value is inputed into the system. With LED display showing “Mode 7” you have to enter the
overload alert value for that vehicle / application. In our example we will enter the overload alert
value of 4500.
Use paper clip to access buttons “M” and “Arrow Up”.
Make sure 0 number is inputed for digit 5.
(In our example for overload value of 4500 has only 4 digits)
As soon the last digit is inputed into the system Mode 7 will change to Mode 8 which is the
normal operational mode
Example: If the lifted load is above preset overload value of 4500 the LCD display will
* Show actual overload value
* LED display showing the overload value will “flash”. (Optional buzzer will be activated as well)
* Overload value alert will stop “flashing” when loaded forks are lowered to the ground.
