Page 3: Overview
Overview The Weighlog 2 is intended for use on skid-steer loaders, utility tractors with a loader attachment, wheel loaders, backhoe loaders (loader side only) and gas powered fork lifts. It measures, displays and records the net weight lifted, normally based on sensing the lift system hydraulic pressure. - Page 4 Overview The front panel has 3 buttons. The lower two are used most often, while the third button is behind the logo. This button is used to enter the program mode.

Page 5: Maintaining Accuracy
2 - Maintaining Accuracy The Weighlog translates pressure (or strain) to weight by means of a calibration factor programmed into the instrument. The accuracy of the system depends to some extent on the following : Machine requirements Operating Temperature : Always allow the machine and the hydraulics to warm up to the normal operating temperature before commencing weighing. -
Page 6: Preliminary Checks
3 - Preliminary Checks Select channel Fig. 3 Ensure that the correct channel is selected for the attachment / commod- ity / trailer to be weighed. Simply press the button to cycle through the channels. Check / change weighing mode Fig. -
Page 7: Check Zero Weight (Check Tare)
3 - Preliminary Checks Check Zero Weight (Check Tare) Fig. 6 You should check the zero weight regularly as part of the daily operating routine. ALWAYS check zero weight if the machine has been left idle for some time and has cooled down. The lifting procedure is different for Dynamic and Static weighing modes. - Page 8 3 - Preliminary Checks Zero Weight (Set Tare) The weight should be zeroed if the Fig. 9 weight reading for an empty bucket is more than ±0.02 (20 kgs) or in "USA" units ±40 (40 lbs). Ensure that the hydraulic system is up to it's normal operating temperature.

Page 9: Weighing
4 - Weighing There are two fundamentally different ways of weighing with the Weighlog - Dynamic weighing and Static weighing. You can select the weighing method for each of the five channels on the instrument. Dynamic weighing Dynamic weighing means that the weight is measured without interrupting the lift. -
Page 10: Reset Totals
5 - Reset Totals Reset Sub Totals Channels 5 can reset independently. Select the appropriate channel 1 - 5. Press and hold the Remote Enter button for 5 seconds. The display will flash 5 times and then go to zero. The TOTAL channel is not affected. -
Page 11: Calibration
6 - Calibration Weight Calibration Accurate results from the Weighlog can only be achieved if the calibration procedure has been carried out carefully and in the correct sequence. You must set the zero weight of the empty bucket/forks/trailer and a weight calibration factor, for each channel to be used. -
Page 12: Calibration Procedure
6 - Calibration Calibration procedure Decide which attachment/commodity applies to which channel. Make a note of this on the chart provided at the back of this manual. Decide whether static weighing or dynamic weighing is appropriate. Select the appropriate channel and then select the weighing mode - "StAt" or "dYn"... -
Page 13: Calibration Example
6 - Calibration 6.2.1 Calibration example Calibrating a front end loader with a bucket capacity of 1.5 tonnes. Set the calibration factor initially to 1.500. A bucket load is weighed and the Weighlog reading is 1.15 tonnes. The same load is weighed on the weigh scales and the true weight is 0.850 tonnes. Using the correction calculation : Correct factor = existing factor x true weight... -
Page 14: Select Units
6 - Calibration Select Units The display resolution can be set to Fig. 16 suit "lbs" readout or "tons" readout. Select the TOTAL channel. Hold the button. The display will show either "Eur" for tons or "USA" for lbs (fig. 16). Fig. -

7 - Faults Error message: "Prog" The instrument memory has been corrupted. You can attempt a "Power On Reset". Switch the power supply off. Press and hold all three buttons and switch the power on. If the instrument can recover itself, it will perform a short self test routine and return to the normal display. - Page 16 8 - Notes Channel Attachment/Trailer/Commodity Weighing Mode Cal. Factor...
