1. Overview
1.1. The System
The Liftlog 1000 is a weighing system designed for use principally on counterbalance fork lift trucks. It measures, displays and
records the net or gross weight lifted, normally based on sensing the lift system hydraulic pressure. Normally, a weighing start
point is established by use of a magnetic Reference position sensor fitted on the lift mast. Without the reference sensor
however, the weighing cycle can be started at any lift height (while still allowing the load sufficient height to drop while
weighing).

Triggering the weighing cycle operates a solenoid on a custom, flow-regulated valve, causing the lift cylinder(s) to drop at a
controlled rate while the hydraulic pressure is measured and averaged over the sampling period. The weight is then displayed
either as a gross weight, or if a tare value has been set, then the net weight can be displayed.
1.2 System Accuracy
With careful operation and observing the recommended weighing procedure (ref. section 3.1 –“Getting the Best Results”), you
can expect accuracy of ±0.5% of the maximum load capacity (e.g. ±5kg lifting 1000kg). It must be stressed however that this
degree of accuracy although possible, cannot be guaranteed since it depends on factors beyond the scope of the system, such as
the condition of the truck and reliance on the operator.
NOTE: Liftlog 1000 weight readings are not suitable as a legal basis for the sale of goods.

2.2 Auto or Manual Weight Entry Mode
Press to select the mode.
In AUTO mode, the weight is automatically added to the Load Total after the “Auto-Add Delay” period. The key
does not function for weight entry.
In MAN mode, the weight is entered with the key, or alternatively by means of a Remote Enter Switch if fitted
(optional).
NOTE: In Auto-entry mode, there will be a delay after the weight sampling time, before the weight is added to the accumulated Load
Total. The delay period is set by the “Auto-Add Delay” parameter in the “Sensor Setup”menu (ref. Inst. And Calibration manual).
The factory default delay time is 2 seconds.
2.3 Select Gross / Net Display
If you have set a tare (either a preset tare or by lifting), then you can display either gross weight or net weight. The status bar
indicates the current tare setting, units and the gross/net setting as per the example below where “PT = 50” is a tare of 50lbs.
NET WEIGHT GROSS WEIGHT
Simply tap the Load Total figure to switch the display.

2.4 Set a Tare
To calculate net weight of the product, you must first enter the weight of the empty pallet / container. Either,
There are two ways to set a tare weight, either by selecting a Preset Tare from a list, or by lifting the empty container.
2.4.1 Select / Edit a Preset Tare (“MAN” Tare)
Press to select a Preset Tare from the list of 50 presets.
By default, the presets are named “User Tare 0” to “User Tare 49”.
Edit the Preset Tare description (a maximum 9 characters are
displayed on the status bar).
Edit the Preset Tare weight.
Cancel and de-activate the Preset Tare function.
The Preset Tare (“PT=”) weight / name (e.g. “GMA”, “48x48” etc),
alternates on the status bar.
NOTE: If a zero-value preset is selected, then the “PT” indicator does not appear in the main screen status bar. The Gross / Net lifted
weight figure will be the same. However unless cleared, the accumulated Gross / Net Load Total figures will account for any tare
set for previous lifts.

2.4.2 Set a Tare by Lifting (“AUTO” Tare)
Press and lift the empty pallet / container to the weighing start
point.
Follow the screen prompt.
You may wish to make this tare as a new preset or to adjust an existing
preset, in which case select and edit the chosen preset as
required (2.4.1).
2.5 Memory Stores and Load References
There are 100 memory stores available to select, to which you can save accumulated Load Totals and their Lift Counts. By
default, the memory stores are named “Store 0” to “Store 99”. The description can be edited as required. In addition to selecting
a memory store, you can also include an additional text reference to be associated with the load.
The memory has a maximum of 1000 storage spaces, so only the last 1000 weighs (lifts) will be saved. Beyond this, earlier lift
records will be overwritten.
It is therefore important that regular data export / printing of load information is carried out, so that older data is not lost
through automatic deletion.

3. Weighing
3.1 Getting the best results
To ensure the best possible accuracy and repeatability, it is recommended that the operator observes the following
recommendations:
Operating Temperature Always allow the machine and the hydraulics to warm up to the normal operating temperature
before commencing weighing.
Weighing on level ground : Avoid weighing when on a slope or a side slope. Wherever possible weigh on a level area. This
also includes weighing with the forks level.
Vehicle movement : Best results are obtained when weighing while the vehicle is stationary. It is important that the load
does not bounce or jerk as it is lifted.
Maintenance and calibration: Keep your machine maintained in good condition. Things like excessively worn bushings, pivot
pins and slideways, as well as lack of lubrication to these areas can have an adverse effect on weighing accuracy. After any
major servicing particularly if you have replaced worn components or carried out welding repairs, you should re-calibrate the
weighing system. If the hydraulic system has been drained and re-filled you should also check for any air that may have
become trapped at the pressure sensor.
Load placement: Maintain a consistent loading method, and in accordance with normal, industry-recommended safe
practice.

3.2 The Weighing Cycle
4 bars “- - - -“are displayed when not weighing.
1. Lift the load up to the weighing start point and then press .
If a height reference sensor is installed, the key only appears
when the weighing start point is reached. The indicator will bleep and
display .
2. Press to weigh.
3. The forks will then drop slowly for a short time as the display counts down to
zero and the weight is measured, after which the forks stop lowering.
NOTE: The rate at which the forks drop is determined by the setting of the drop
valve during installation. Any subsequent adjustment must only be made by
a trained installer.

The hydraulic pressure reading is sampled continuously as the forks
drop, and the average weight is then is calculated and displayed.
If ‘AUTO’weight entry mode is set, the weight is then added to the
accumulated Load Total and the Load Count will increase by 1.
NOTE: There may be a short delay depending on the “Auto-Add Delay” setting via
the “Sensor Setup” screen in the Setup menu.
If ‘MAN’weight entry mode is set, then press the key, or if fitted,
the Remote Enter pushbutton switch (optional).
3.3 The Load Indicator / Overload Alarm
10 –70% 70 –90% 90 -100%
All blocks flash if overloaded (more than 102% of maximum load), and continuous alarm tone is emitted from the indicator, and
also an external audible alarm sounder in tandem if fitted (optional).
NOTE: The load bar feature is enabled or disabled via the “Overload” screen in the Setup menu.

3.4 Clear Last Weight Entry (“CE-1”)
If a weight is entered in error, press then to subtract the entry from the memory totals ("CE -1").
A negative weight entry is saved to the selected memory store to effectively cancel out the last weight entry. The negative
weight will also appear on the list of individual lifts on a printout, or data saved to an SD card / USB stick if enabled.
3.5 Reset Load Total to Zero
Press to reset the Load Total to zero.
The load information is saved to the selected memory store along with any text reference entered. The Load Total may also print
or save to SD card / USB stick, depending on the “Logging Options” settings. The Store setting resets to “Store 0” and text
reference to none.
3.6 Memory Used Indicator
The memory usage indicator is a reminder to the operator to download or print data before the memory is full, after which the
earliest load record will be automatically deleted each time a new load is entered.
Once the memory becomes 75% full, a reminder is displayed each time
the indicator is switched on.
The memory can store a maximum of approximately 1600 weighs
excluding text references. If text reference are included, you can
expect a memory capacity of between 1000 -1200 weighs.
