Safety
Always disconnect the vehicle battery before installing SkidWeigh systems. Make sure that the digital indicator, 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 component cables and where they will be protected. Use commonly accepted install practices for
after market industrial vehicle electronic devices. The installation of SkidWeigh systems should only be performed by an
acknowledged lift truck technician or other with competent knowledge of electrical and hydraulic systems.
Here are two acceptable methods of making a wire connections:
1.Soldering your connections (recommended)
2.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 digital indicator.
Electro-Magnetic Compatibility
CE conformity to EC directive 89/336 (EMC) by application of harmonized standards: Interference stability EN 61000-6-2

SkidWeigh ED2-SM Version 1500
Our policy is one of continuous improvement and the information in this document is subject to change without notice.
Check that software version displayed on the LED display is reflective of this manual.
Overview of Components
The standard SkidWeigh ED2-SM check weighing system kit consist of two main components:
* Digital indicator with external overload audio warning, wiring harness and anti-vibration mounting bracket.
* Hydraulic pressure transducer with 3 wire connection cable.
* Installation & calibration manual as well as quick reference operator usage instructions.
Operational Principal
The SkidWeigh ED2 operational principal is based on
mounting a pressure transducer into the vehicles hydraulic
lifting circuit between the lift control valve and lifting cylinder(s).
Upon usage proprietary software will automatically activate
the “weighing cycle algorithm ” when a skid load is lifted just
above the ground. The increase in pressure is converted
through an electronic signal at the sample rate of 16000
readings per session which is then converted into a load
weight reading.
Installing the Pressure Transducer
The pressure transducer must be installed in the hydraulic lift
line between the lift control valve and lift cylinder(s). 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
or in the body of the flow divider. Also, you can drill and tap
on any “larger elbow” that might be available in the hydraulic
lift circuit found in vehicles with larger hoses to accommodate
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 at their lowest position and
make sure the hydraulic system pressure is completely 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 lift cylinder into its lowest position. Ensure that the chain(s) is slack.
Make sure that that pressure transducer when installed will not
touch or obstruct any assembly or moving parts during
operation. The pressure transducer has a 1/4”-18 NPT male
thread. Use thread seal to ensure tight fit.
Selecting the Mounting Location for
the Digital Indicator
Use the anti vibration mounting bracket and fasten the digital indicator on the vehicle dashboard, side rail, or over head
guard, preferably on the right hand side. There are many examples of mounting locations that will depend on the vehicle
model. Each SkidWeigh ED2 kit comes complete with flat universal mounting brackets designed for mounting on the
overhead guard.
Choose the correct location and make sure that:
1. The Indicator is visible and within reach of the operator.
2. The location does not impede the operator safety entering the vehicle or obstruct operational sight lines

‘Quick Test’ System Check
Note: The following ‘Quick Test’ allows the installer to ensure that the both the electrical connections and
the installation of the pressure transducer have been performed correctly. Also note the SkidWeigh system
is not to be calibrated at this stage.
After you have connected electrical power and the pressure transducer cable you can check system operation following
these steps.
1. Lower the forks to the ground.
2. Turn on the ignition switch.
-The digital LED display will be activated showing the software version and serial number.
-The number 8will be shown on the LED display above the Mode symbol.
3. Lift the forks above the ground with a load to activate the weighing cycle.
-Mode 8 will disappear and within a few seconds a load weight will show on the LED display.
If the system responds as per the above test the electrical connections and pressure transducer are installed
correctly. The load weight will not be accurate as the system has not been calibrated at this point.
Hydraulic Accumulators
The following applies to lift trucks equipped with hydraulic accumulators.
Note: Before installation please ensure that the system was ordered specifically for trucks equipped with
hydraulic accumulators. If not please contact technical support for confirmation and or a system with the
correct software configuration.

Calibration Procedure
The SkidWeigh ED2 calibration cycle is a simple and automatic process that is completed by lifting both empty and
loaded forks, and or attachment, and programming the weights into the system. The entire process takes
approximately 3 minutes and will require the following to be completed in advance.!
1.The paper clip supplied with the system or like.!
2. A pre-weighed load in order to set an accurate programming standard into the system. Use an existing floor
scale to verify the actual weight or a trusted accurate shipping label. For best results try to secure a load test weight
that is 30 - 50% of the maximum lifting capacity.!
Note: The system can show the load weight in either pounds or kilograms, but not simultaneously.
Therefore, calibrate in the preferred measurement unit.

Calibrating the System with a Load Weight
6. With the LED display showing 0 at the far right it is time to enter the known weight secured prior to the calibration
process. Using the paper clip enter that weight beginning with Mode 1through 5, for weights in excess of 9999 lb./kg.
If the weight is 9999 or below enter 0 for Mode 5. See the example below.
(In our example we will use the known load weight of 4000)
First least
significant digit “0”
Second least
significant digit “0”
Third least
significant digit “0”
Forth least
significant digit “4”
Fifth least
enter “0”

3. To begin the calibration process press the M button, using a paper clip and
hold for few seconds. Eventually the 8will change to 0above the mode indica-
tor. System is ready for automatic zeroing.
4. With the indicator showing 0lift he empty forks approximately 2” - 4” off the
ground. With the vehicle stationary do not manipulate the tilt, side shift,
or fourth lever function during the lifting process. Activate as you would
normally during operation of the vehicle.
5. Within a few seconds of lifting the forks, the LED display will go blank and the
digit 1will show above the Mode Indicator. On the far right side of the display a
default 0will be shown if the system is being calibrated for the first time. If a
recalibration is being performed then the digit programmed from the prior ses-
sion will show instead.
Automatic Zeroing is Complete.

Entering Overload Warning (ED2-SM SkidWeigh Series)
If the SkidWeigh ED2 Series system utilizes the SM (Overload) function) than the system will automatically
default to MODE 7 when the loaded forks are lowered to the ground.
Using the “M” and “Up Arrow” buttons enter the
overload weight value for your application similar to
the process when calibrating the system with a load
weight except the MODE 7 digit remains throughout
this operation. Once the last digit has been entered
MODE 7 will disappear.
The overload weight value is now successfully stored
into the system memory.
Example: Below is an example of a desired overload weight of 4850. As per the calibration process for value 9999 or
less enter 0 for the 5th digit.
System is calibrated for both weight and overload warning

7. With the system at Mode 5, after entering all digits, drive into the secured palleted
load. Once the loads is secure on the lift truck make sure that all pressure is out of the
hydraulic system by lowering the forks till the lift chains show slack.
8. Using the paper clip press the M button to advance to Mode 6.
9. Lift the known weight 2” - 4” off the ground similar to the zeroing process.
With the vehicle stationary do not manipulate the tilt, side shift, or fourth lever function
during the lifting process.
Activate lift control lever and lift load as you would normally during operation of
the vehicle.
After few seconds the LED display will show calibrated load weight.
System is now calibrated.
