TESTER SWITCH ON
The LC Tester1008 shows the following display for about 2 seconds where Firmware and Software
Rev. are displayed.
Then, select the number of load cells connected to the junction box mod. CGS4C -CEM4C (or other)
and confirm with “V” key.

Page 5
SIGNALS DETECTION
The LC Tester 1008 automatically detects the input impedance values of the load cells connected,
choosing among the 4 available values “ 350Ω, 700Ω, 1000Ω e 2000Ω”.
The detected values can all be changed if the load cell impedance is different from the 4 available
values.
Note: The impedance values result in a variation in the reading of the individual signals of each load
cell.
During impedence measurement the LC Tester 1008 displays :

Page 6
TESTER FUNCTIONS
The LC Tester 1008 allows the simultaneous display of the “mV / V” signal of each load cell, of the
weight “Kg ..gr..t..lb..N..KN”, of the percentage of the single load “ % FS “ and their distribution”% “.
Note: The parameters in the “Weighing Data” Menu handle the correct detection of the individual
weights displayed by the LC Tester 1008.
It also detects the integrity of the load cell and its electrical connections.
Any anomalies are indicated as follows: No Exc-, No Exc + and Signal.
The LC Tester 1008 has the “Peak” function. It detects “Kg ..gr..t..lb..N..KN” weight values ??and
their “mV / V” signals.
The detected peak values ??can be saved and displayed in the “HOLD” screen.
The LC Tester 1008 is equipped with the Autotare function resulting in the reset of the “Kg..gr..t..lb..N..
KN” weight values, load values ??”% FS” and distribution “%”.
The LC Tester 1008 can receive and transmit the weight display setup configuration for the mod.
DAT400, MC302, MCT1302 via serial and DAT1400 via NFC connection.
The LC Tester 1008 is also a mV / V signal simulator.

The displayed “squared boxes” depend on the number of load cells selected when powering on the
LC Tester 1008.
The change of the displayed values determines the display of the following alternative screens:

Page 8
TESTER FUNCTIONS
The following displays can be selected with the key: >>
Display of “Kg” load values and
“mV / V” signal values.
The displayed values are the
weight in Kg applied to each
load cell and its “mV / V” signal.
Pressing around “Gross Weight”
it activates the autotare function
and the display shows “Net
Weight”, resetting the weight
values, the load percentage and
the distribution percentage.
Pressing again it restores the
gross weight function.
Display of load percentage and
weight distribution percentage
The displayed values are the
load percentage applied to
each load cell their distribution
percentage.
Display of the load cells input
resistance.
The impedance of each load cell
is expressed in Ohm.
It is possible to manually change
each impedance value by cli-
cking directly on the value itself
and setting the new value. When
rebooting, the values calculated
by the LC Tester 1008 tester are
restored.

TESTER FUNCTIONS
In order to enable peak and hold functions, press impulsively on the squared box of the “Gross Weight
and Signal (mV / V)” display.
Note: Peak function only activates from the “Gross Weight and Signal” display.
The value on the left correspon-
ds to the actual weight of the
detected peak.The value on the
right corresponds to the signal
in mV / V of the load cell corre-
sponding to the weight value of
the detected peak.To delete the
detected peak values, press one
of the squared box for about 2
seconds.
The pressure, for about 2 secon-
ds, of one of the four squared
box allows storing individual
values.
The display shows the Hold di-
splay automatically.
To delete stored values, press
one of the squared box for about
2 seconds to return to the main
display.

TESTER FUNCTIONS: AUTOTARE
The Autotare function activates by pressing the display in the highlighted area
By pressing the highlighted area
again the gross weight function
is restored and the autotare per-
formed is cancelled.

ADJUSTING OUTPUT SIGNAL
The signal adjustment is managed with the cursor keys next to the Bar graph.
By holding the end adjustment keys there is a continuous signal adjustment.
The signal can be reduced to negative values up to -2.8 mV and reach the maximum value of +20.3 mV.
It is possible to manually set a value in the Signal squared box.
The Key generates the 0 mV/V Signal.
The Key generates the average Sensitivity Signal of the load cells.
In case this value is not set the default value is 2 mV/V.

Page 12
By clicking on the area “Signal” it is possible to set the desired value of
the mV/V signal to be generated.
The key performs the Autotare of the Gross weight.
In the box “weight” the heading becomes “Net weight” and the Zero Key changes and becomes:
.
By holding the Key the performed Autotare is cancelled and in the box “weight” it is
displayed “Gross Weight”.
The LC Tester 1008 simulates signals espressed in mV/V and generates the weight.
Note: The correct display of the weight generated, assumes that the parameters WEIGHING DATA:
 “Load Cell Number”, “Load Cell Sensitivity”, and “Single Load Cell Capacity” are set correctly.
Example:
If the instrument to be checked is normally connected to 4 load cells of 250 kg, 2 mV / V, the LC Tester
1008 must have been programmed as follows:
Number of load cells = 4
Unit of measurement = Kg
Division value = 1
Single load cell capacity = 250 Kg
Load Cell sensitivity 1 = 2.0000
Load Cell sensitivity 2 = 2.0000
Load Cell sensitivity 3 = 2.0000
Load Cell sensitivity 4 = 2.0000
Capacity = 1000 Kg.

NFC COMMUNICATION
Data exchange mode with DAT1400 with NFC option.
NFC
When receiving or transferring the file using NFC, place the LC
Tester 1008 aerial, located in the back of the container above the
batteries compartment, close to that of the instrument. When the LC
Tester 1008 has established the communication with the instrument,
the word “Reading in progress” (or “Writing in progress”) will ap-
pear. After about one second, if the data exchange is successful,
the word “Reading completed” or “Writing completed” will appear.
Note: Function only possible with the DAT1400.

FILE MANAGEMENT FROM PC
File management functions (erasing, renaming, etc.) can only be performed from a PC via USB con-
nection (ABC cable). The PC will recognize the LC Tester 1008 as a USB remote disk.
There are two folders inside of it:
“CONFIG” containing the indicators set up files.
“INSTR” containing the system parameter saved files and the LC Tester 1008 signal files (.CSV format).
