1 Calibration Summary
The LM 800i/8000i system operates in a Non-Approved weighing mode. Dynamic or Static weighing is
possible. The system is designed to be easily upgradable for Weights and Measures approved operation,
either for automatic weighing (AWI) or non-automatic weighing (NAWI).
There are a large number of functions within the calibration menu in order to optimise the performance of the
weighing system for a particular loading shovel and the method in which it is to be used. Many settings need
only be made on the initial installation.
The calibration procedure is summarised below. For full information on any of the settings in the calibration
menu (ref. Section 4).
Step 1 Work the machine until it is up to the normal operating temperature.
Step 2 Go to the "Sensor Setup" menu (ref. section 2.1)
(i) Set " am atio" The default value of 1.3000 is OK initially, for almost all makes and models of machine.
Known figures are given below.
Machine Ram Ratio
VOLVO L120, L150 1.34
ALL KOMATSU 1.30
ALL CASE 1.30
ALL CAT MODELS 1.25
For other machines, you can determine the correct ram ratio by the following method: - Do a slow lift and then
a fast lift. If the weight readings are the same, the Ram Ratio is correct. If the fast lift reading is greater then
reduce the ram ratio, and vice versa.
(ii) Set "Dual Sensor" to "DIFF".
(iii) The default settings for "Live Static" (AUTO), and "Mode" (DYN/STAT) enable both dynamic and static weighing
modes, and a live readout for the "last bucket" weighing mode. If you require static weighing mode only or
dynamic weighing mode only, you must change these settings accordingly.
NOTE: Some CASE and Liebherr machines shou d be operated on y in Static weighing mode.
Step 3 Go to the "Auto al" menu (ref. section 2.2)
Follow the screen prompts for the calibration routine ("Dyn. Diff Setup", “Static Empty Lift”, "Dyn. Speed
Comp.", “Static Full Lift”, "Static Comp.", "Zero" and then "Cal Weight"), to establish accurate weighing. To
perform the weight calibration ("Cal Weight"), load the bucket (preferably to its full capacity) with a known
weight of material.
NOTE: If you don't know the exact weight, you can make an estimate and then use the "NUDGE" faci ity afterwards to
correct the ca ibration factors.
The calibration figures resulting from the AUTOCAL procedure will apply to loading attachments 'A' to 'H'. To
ensure accurate results when using a different attachment, adjust the calibration using the NUDGE facility.
Step 4 heck the weight reading (ref. section 2.4)
Zero the system and load a truck. Note the weighbridge (weigh scale) reading against the instrument reading.
If they are different, use the NUDGE facility to enter the two readings. The calibration factors are adjusted
automatically.
Step 5 Operator Instruction.
Please discuss the loading sequence and loading routine with the operator(s) of the loading shovel. Ride with
the operator and explain the weighing methods, auto kick-out, auto / manual entry, and the importance of
smooth operation while weighing.

2 Loadmaster 800i/8000i - Common Calibration
2.1 Sensor Setup
Sensor setup should be done before any other calibration. The sensor settings apply regardless of which
attachment is selected.
Select the 'Sensor Setup' screen (figure. 2).
*Default Factory PIN = 4084
"No. of samples" is the number of times the instrument takes a signal
from the pressure sensor(s).
"Sample Time" is the time taken for each sample in seconds.
"Auto Static" is the time delay after reaching the weighing position
before the instrument samples the weight. This delay allows the system
to settle down and helps to give consistent readings.
"Live Static" -The 'Off' setting has the effect of 'freezing' the weight reading when weighing in Static weighing
mode. The 'On' setting allows a 'live' readout when the bucket is in the weighing position. This is not suitable for
'weighing on the move' operation. See '2.3.2 Static Compensation' for the best setup for 'live static' weighing.
“Static Speed” - Enables speed compensation for static weighing. This setting needs to be switched ‘On’ for
certain machines, and in particular, CAT 9 , 972 and 980 models. The majority of other loaders will not
require ‘Static Speed Compensation’
"Dual Sensor:" "Off" Single load sensor installation
"Dual" (Not used)
"Diff" Dual pressure sensor installations (Static or Dynamic operation). The second sensor measures back-
pressure on the return side of the lift ram circuit.
"Sum" Strain sensor applications. Sensor readings are added.
"Avg" Strain sensor applications. Sensor readings are averaged.
The 'Dual Sensor' setting should always be set to 'Diff'. This enables the system to zero at any lift speed..
"Ram Ratio" is the ratio of the area A1/A2 of each side of the ram piston (figure 3). The default value of 1.3000
is OK initially, for almost all makes and models of machine. You can determine the correct ram ratio by the
following method. Do a slow lift and then a fast lift. If the weight readings are the same, the Ram Ratio is
correct. If the fast lift reading is greater then reduce the ram ratio, and vice versa.
Figure 3
"Nudge Key" - The option to switch off the NUDGE facility so that it no longer appears on the 'SETUP' screen.
"Zero heck" - Enables the "ZERO CHECK” function. (Default 'OFF' for LM800/8000).
"Mode" - This selects which weighing mode should be used. On LM 8000 models, "Dyn/Stat" is the default.
"Dyn" only or "Stat" only can be selected.
"Angle Sensor" Optiona .
Enables the angle sensor input and selects the vertical axis orientation of the sensor. Select the icon matching
the orientation of the electrical junction box (looking forwards from the cab).

“Sample type” : “STD” sets the system to sample a dynamic weigh procedure in the standard format, as used
in the Loadmaster 8000 series with earlier S/W version PS300-02 rev.38
“ADV” sets the system to sample a dynamic weigh procedure in a new format. This mode should generally be
selected, as it should be consistently more accurate in use.
Where this option is selected it will be necessary to mount the Ref / Dir sensors about 200mm from the boom
pivot pin, centre,set.
2.1.1 General setup for loading shovels
Check that the initial settings are as given below. These are suitable for
almost all makes and model of machine whether operated in Dynamic
weighing mode or in Static weighing mode.

2.2 Auto Cal
After "Sensor Setup", do an "Auto Cal".
The instrument will automatically advance from Auto Cal step 1 (Diff.
Setup) to step 5 (Cal Weight). You can however, still select from the
Auto Cal menu in any order.
2.2.1 Dyn. Diff. Setup
This function is active only when the "Dual Sensor" setting on the "Sensor
Setup" page is set to "Diff". Diff. Setup compensates for oil temperature
(LM 9000 only) and backpressure fluctuation in the hydraulics.
Follow the screen prompts.
Lift an EMPTY bucket at fast speed and press ENTER.
Lift an EMPTY bucket at slow speed and press ENTER.
The instrument then displays the message " alibration Done". Press the
'ESC' key to continue the Auto Cal. (‘Static Empty Lift’).
2.2.2 Static Speed Compensation (‘Static Empty Lift’)
NOTE: This function is enab ed on y when the "Static Speed" setting on the
"Sensor Setup" page is set to "On", otherwise this screen wi not appear.
Follow the screen prompts.
Lift an EMPTY bucket at fast speed to the static weigh point (kickout),
allow the system to weigh and then press ENTER.
Lift an EMPTY bucket at slow speed to the static weigh point (kickout),
allow the system to weigh and then press ENTER. The instrument then
displays the message " alibration Done".
2.2.3 Dynamic Speed Compensation (‘Dyn. Speed Comp’)
By defau t, dynamic speed compensation is switched off unti the Auto
Ca routine is performed.
Fast Speed calibration (Use Loaded Bucket)
Fill the bucket (you don't need to zero beforehand). With the menu
pointer opposite the symbol, lift the bucket at full speed. The
instrument will bleep once then display the frequency output of each
pressure sensor, and the lift speed in milliseconds.
Press ENTER to confirm. The menu pointer will then move opposite the
icon and display the prompt "Slow Lift" (fig. ).

Slow Speed calibration
1. With the menu pointer opposite the symbol, lower the bucket then
slowly lift through the weighing position again. If you lift too quickly, the
display will flash 'Error'. If so, lower the bucket and try again. The
instrument will bleep once, then display the frequency output of each
pressure sensor, and the sample time in milliseconds (fig. 7).
2. Press ENTER to confirm.
3. The instrument then displays the message "Speed ompensation Set".
4. Press the 'ESC' key to continue AUTOCAL (Static Full Lift).
NOTE: The percent figures re ate to the 'Proportiona Sca ing' function. This
function predicts the difference in Speed Compensation required for ight
and heavy oads in the bucket. This compensates for hydrau ic
inefficiencies and the frictiona behaviour of the ift system.
2.2.4 Static Speed Compensation (‘Static Full Lift’)
On machines where a substantial difference in displayed weight is experienced with changes in engine speed /
speed of lift (for example G series Caterpillar loaders) this option can be turned to ON. Doing so will enable
the Static Speed Compensation items within the Autocal menu and will turn on the Speed Compensated Static
weighing function. This will allow the Loadmaster to apply a compensation value to the displayed weight
based on the speed of lift, and should result in far more stable displayed weights where changes in speed of
lift are experienced.
NOTE: This function is enab ed on y when the "Static Speed" setting on the "Sensor Setup" page is set to "On",
otherwise this screen wi not appear.
Follow the screen prompts.
Lift a FULL bucket at fast speed to the static weigh point (kickout), allow
the system to weigh and then press ENTER.
Lift a FULL bucket at slow speed to the static weigh point (kickout), allow
the system to weigh and then press ENTER. The instrument then
displays the message "Speed ompensation Set".
2.2.5 Static Compensation (‘Static Comp’)
By defau t, Static Compensation is switched off unti the Auto Ca routine
is performed.
Static compensation takes effect when the bucket is stationary at the
weighing position. It enables the live static reading to become more
stable over the sampling period and improves the accuracy of the weight
reading.
Calibration is fully automatic. At the screen prompt, lift a FULL bucket
SLOWLY to the weighing position. The screen then plots two graphs
each with 30 samples for load sensors A and B (something similar to fig.
8). The calibration routine runs for 45 seconds and then displays the
message 'Calibration Done'.
Press the 'ESC' key to continue AUTOCAL (Zero).

to set "Dynamic Zero" is automatic.
2. Lift the bucket to the weighing position. The instrument will bleep twice. ENTERING to set "Static Zero" is
automatic.
3. Press the "ESC" key to continue AUTOCAL (Cal Weight).
NOTE: Sticky materia , bucket wear, or fau ty e ectronics can cause variation from zero.
Zero the system for each each different attachment used. Zero measurements are viewed on the “Dynamic
Factors” and “Static Factors” screens.
2.2.7 Cal Weight (Weight Calibration)
If both dynamic and static weighing (Dyn/Stat) mode is enabled, then
both a dynamic calibration routine and static, weight calibration routine
are performed. If either dynamic weighing only ("Dyn"), or static weighing
only ("Stat") mode is set, then the appropriate calibration routine will
apply.
1. Zero the empty bucket.
2. Load the bucket (preferably to its full capacity) with a known weight of
material.
NOTE: If you don't know the exact weight, you can make an estimate and then
use the "NUDGE" faci ity afterwards to correct the ca ibration factors.
3. Select the "Cal Weight" screen (fig. 9).

2.3 Calibration Factors
The previous pages cover "Sensor Setup" and "Auto Cal" on the "Calibration" menu. With the exception of " .
Surge Factors" , the menu items,
2. Static Factors
3. Dynamic Factors
4. Dyn. Comp. Factors
5. Stat. Comp. Factors
. Surge Factors
7. Angle Factors
simply display the factors resulting from the Auto Cal routine for the
attachment selected. Also, Speed compensation/Static Compensation
can be switched on or off.
2.3.1 Displaying Static/Dynamic Factors
These are the factors resulting from the AUTOCAL routine. From the
"Calibration " menu, select "2. Static Factors” or "3. Dynamic Factors" to
display them (fig. 17a). The Zero factors are also stored here. The first
Zero factor (for both A and B sensors) refers to the initial Autocal Zero
which is carried out on initial verification. The second Zero factors is the
frequency stored at the initial switch on bucket Zero. The third Zero
factor is the frequencies stored during any other Zero routine. These are
used to perform the Zero Setting Checks.
2.3.2 Dynamic Speed Compensation Factors (Dyn. Comp. Factors)
From the "Calibration" menu, select "4. Dyn. omp Factors". There are two screens displaying various factors
that can be edited if required (17b, 17c). Press to advance to the second screen.
The first screen enables Dynamic Speed Compensation and Proportional Scaling to be switched on or off.
NOTE: There are two Speed compensation options: - "Type 1" and "Type 2". After performing the Auto Ca routine,
Speed Compensation is automatica y set as "Type 1" ( ). For hydrau ic systems, Type 1 ( )
shou d be set.
The second page shows the ift speed a arm imits in mi iseconds. If the ift speed between the reference sensor
and the direction sensor is faster than the “Fast Time” (the sma er va ue), the symbo appears on the MAIN
screen. If the ift speed is s ower than the “S ow Time” (the arger va ue), then the symbo is disp ayed.
“Curve A” and “Curve B” give the correction for the change in ift speed. If a fast ift gives a ower weight reading
than the s ow ift, then the figure shou d be decreased, and a ways –ve e.g. changing –11.0 to –10.0.

Proportional Scaling
Proportional Scaling is used to compensate for efficiency losses in a dynamic or static lift, and is a scaling
factor based on the maximum load of the machine. It is important to perform the Speed Calibration routine
with the maximum load in the bucket.
The “Prop” factors give the reduction in speed compensation for an empty bucket compared to a full bucket.
Sometimes after an autocal, it is found that the speed correction with a full bucket is OK, but with an empty
bucket there is a larger error (e.g. 50 to 0 kg).
If with an empty bucket, the weight reading is lower at a slower lift speed than at a fast speed, then reduce the
“Prop A” factor by 2 - 3% until the error is removed. “Prop B” for hydraulics, is normally left at 0.00.
The normal setting for "Prop. Scaling" is "On".
2.3.3 Static Speed Compensation Factors (Stat. Comp. Factors)
From the "Calibration" menu, select "5. Stat.. omp Factors". There are three screens displaying various
factors that can be edited if required. Press to advance to the second screen.
The Static Comp Factors section consists of three pages of factors.
Page one (fig 18a) sets the speed compensation On or OFF, and allows access to the Proportional Scaling
factors. Tests so far have indicated that there is no advantage to be gained from using the ‘Curve’ function
when compensating for lift speed changes in Static weighing, so the recommended compensation system is
the less complicated ‘Line 2’ setting.
Page two (fig. 18b) allows access to the Fast and Slow lift speed limits, and the speed compensation graph
gradient factors (‘Line A’ / ‘Line B’).
NOTE: ‘Line A’ is the factor that shou d be edited to change the degree of Static Lift Speed compensation where editing
is required. If a fast ift gives a ower weight reading than the s ow ift, then the figure shou d be decreased, and
a ways –ve e.g. changing –11.0 to –10.0.
Page 3 (fig. 18c) displays the Static Last Bucket live reading compensation values. These factors are display
only and cannot be edited.
"Off / On / Auto" (third screen page)
Some machines using the live static mode may operate more accurately if "Static omp" is set to "Auto". Set
"Static omp" to either "On" or "Auto", whichever suits the particular machine.
“Off” No compensation
“On” Uses the calibrated pressure drop compensation curve calculated from the autocal.
“Auto” Produces a live reading, but the reading will only change if there is a change of 1% or more in the
calculated weight.
A / B Zero Freq.
Zero signal from the sensors.

"Max Freq A / B"
Variable compensation is required depending on the load. The Max Frequency figures log the signals at Max
load. This is set up from the Static Comp. routine in the AutoCal.
In order for the instrument to know when it is lifting a fully loaded bucket (to apply the correct compensation),
the maximum signal from each load sensor is saved here.
"Comp eset"
If the frequency changes by a set amount on sensor A over the sample time, the compensation resets itself to
the beginning of the routine. This is normally due to a pressure surge after the bucket is crowded back.
The default is 20 Hz (LM 800/8000) & 0 Hz (LM 9000), with "0" being "Off", Max figure 100 Hz.
2.3.4 Surge Setup (optional)
This enables the instrument to detect a pressure surge due to machine
bounce or acceleration, which may cause an inaccurate weight
calculation. If the pressure surge exceeds an upper or lower limit, a
warning "TOO MU H BOUN E" is displayed on the MAIN operating
screen and weighing is inhibited.
For the LM 800i/8000i, this is normally switched off. It should only be
used if necessary. Start with the default settings.
"Upper Limit" / "Lower Limit"
The "Lower Limit" figure (Hz) is used when the bucket weight is below the "Threshold Weight". The "Upper Limit"
is used when the bucket weight is above the "Threshold Weight".
Raising the settings produces a less sensitive Surge Inhibit Alarm
Pre-set values are defined by the certification option selected (section 3.3.1) from the "Sensor Setup" menu.
Once the machine is used, the upper/lower limits can be adjusted if necessary.
"Threshold Weight"
The threshold weight = 50e. E.g. if the Scale Interval 'e' is 20kg, then the threshold weight is 1 tonne.
2.3.5 Angle Factors (Optional Angle Sensor)
Weighing is inhibited when the system is used at angles exceeding those
set on this screen (fig. 20). An alarm will sound and the angle error will
be displayed on the MAIN operating screen.
indicates the angle at which weighing will be inhibited.
The other compensation factors are calculated from the angle
compensation routine in Auto Cal.
NOTE: If re-ca ibration of the ang e factors is required, make sure that a the
factors for Up/Down/Right/Left are manua y set to zero before carrying
out an AutoCa .

2.4 'NUDGE' Calibration
You can nudge the calibration figures up to 10%. If the error is more than
10%, the instrument will prompt you to re-calibrate (" al Weight" in the
Auto Cal menu).
This function is switched on or off from the 'Sensor Setup' screen in the
SETUP menu “1. alibration”. By default, it is switched on.
When to nudge the calibration
After performing the initial weight calibration and loading a few trucks,
you may find that the load readings from the instrument are consistently
different from weighbridge (weighscale) readings. This situation can also
occur after maintenance or repair to the loading shovel e.g. changing a
bucket.
How to nudge the calibration
1. Load a truck and note the weighbridge total against the instrument total
for that load, e.g.
Scale reading: 24.78 tonnes
Instrument reading 23.9 tonnes
2. Press to select the 'Nudge' screen (fig. 22).
3. Enter the instrument reading ( ) and press ENTER (fig.23).
4. Enter the weighbridge reading ( ) and press ENTER (fig 24).
The percentage difference between the instrument and weighbridge
totals is then displayed. Press the ENTER key to confirm. All dynamic
and static factors are automatically re-calculated and stored in memory.
The screen displays the message 'New Factors Set'.
5. Press the "ESC" key to return to the "SETUP" menu screen, or select the
MAIN weighing screen to exit Calibration mode.
NOTE: To nudge the ca ibration by a known percentage, enter 1.000 tonne for
both the and figures, then enter the known percentage
figure and press ENTER to confirm.

2.5.1 Programming an attachment
By default the LM 800i/8000i is programmed to recognise only one
attachment. The Auto Cal routine will therefore calibrate for attachment
'A'. You can programme the instrument for up to 8 attachments as
follows: -
1. From the "SETUP" menu, select "1. alibration" (PIN entry required).
2. Press the key (fig. 25) to select the "Attachment" screen (fig. 2 ).
3. Select from the list 'B' to 'H' using the arrow keys and then press the
key to switch on the attachment. Only those that are have a tick against
them will appear to the operator via the key on the SETUP menu.
4. If required, programme an attachment description (up to 20
alphanumeric characters). Simply position the flashing cursor under the
attachment letter using the right arrow key; enter the description using
the alphanumeric keypad.
5. Press "ESC" twice to get back to the "SETUP" screen.
2.5.2 Select an attachment for calibration
1. From the "SETUP" menu (fig.27), press the key to select the
"Attachment" screen.
2. Simply select the appropriate one using the up / down arrow key, and
then press "ESC". The instrument is now ready to be calibrated for that
attachment.
NOTE: The current attachment is a ways disp ayed at the top of every screen.
2.5.3 Calibrating an alternative attachment
Select the attachment from the list,
In the Auto Cal, carry out the Zero function only to set the "Zero Tracking
Device". (Picks up large Zero change during use).
Select the attachment from the list, and then use the NUDGE function to
adjust the calibration. (No need to carry out Diff/Speed comp etc. in the
AutoCal)
EMEMBE ! You must re-calibrate using the NUDGE function, each time you
change an attachment.
NOTE: If an attachment is subsequent y repaired or modified in any way that
affects its weight or centre of gravity (e.g. new bucket cutting edge, teeth
etc), then it shou d a ways be re-ca ibrated

Comma-delimited Output
Set the output mode to "Data". The data is output as a comma-delimited string, e.g. in a format compatible for
import into a database program via a PC / PDA (Palm/Psion etc).
Input/Output to the DS Data Card Module
Set the output to " ard". The instrument writes/reads files in .CSV format to/from the data card.
Input/Output via adio Modem
Set the output mode to "Radio" for telemetry via a radio modem.
The range of a radio telemetry system generally limits use to a single site.
Input/Output via GSM Modem
Set the output mode to "GSM" for telemetry via a GSM device.
Data can then be transmitted between any other site, since data is transmitted via the cellular telephone
network.
NOTE: As well as configuring the appropriate output port for telemetry operation, the telemetry option must be
switched on from the "System Settings" menu (section 4).
efer to the manual supplied with the telemetry kit for full information on telemetry operation.

NOTE 1: The weight tota is rounded up or down, and it is this rounded off figure that is added to a memory tota .
For lbs. or kg units you can set the resolution, i.e. to the nearest 1, 5, 20, 25, 50, or 100 lbs. or kgs.
NOTE 2: When a LM9000 is used in "non-approved" (LM8000) mode, the units are not disp ayed on screen or on a
printout.
Maximum Weight
flashes on-screen with a 3-second continuous beep when the maximum weight limit is exceeded.

NOTE: Requires the Factory PIN number (defau t = 4084)
The calibration factors are manually saved to memory store A. This data is NOT overwritten each time the
instrument is switched off, but it WILL be cleared after a Total Software Reset ("RESET FACTORS"). If for
example, any calibration data is unwittingly changed without keeping a record of previous settings or data is
corrupted, you can restore the calibration data from either of these stores at any time.
NOTE: Shou d the instrument head unit fai , the modu e can be p aced into a new head unit, keeping a re evant
ca ibration data that is stored using this function. Once the modu e is re-insta ed, se ect "Restore from A". This
