If full testing cycle was chosen:

The LCD shows " Test in progress" and the LED blinks for a few seconds.

Once the test is finished you may scroll the results by pressing the up arrow

key. The results will be displayed in the following order:

Input – Resistance between Ex+ and Ex- ( Max 5000Ohm )

Output - Resistance between Signal+ and Signal- ( Max 5000Ohm )

Sense+ - Resistance between Ex+ and Sense+ ( applicable for 6 wires load

cell ) ( Max 5000Ohm )

Sense- - Resistance between Ex- and Sense- ( applicable for 6 wires load cell

) ( Max 5000Ohm )

Signal Output – Load cell signal in percentage of full L/C capacity. Note: in

case of a broken cable or a very high input/output resistance the display

will show " Cannot measure"

Shield to Brdg – Resistance between the cable shielding ( screen ) and the

bridge

Body to Brdg – Resistance between the load cell body and the bridge

Shield to Body – Resistance between the load cell body and the cable's

shielding

Tips for trouble shooting Load Cell and scales

Load cells might be damaged due to many reasons: Overloading, lightning

strikes, moisture or chemical ingress, vibrations, corrosion, pulling the cable etc.

As a result, the scale may provide unstable readings, zero drifting, error reading,

non-linearity etc.

The LCT100 is the only measuring tool required to perform the tests either on

site or in the lab. Before you start, make sure to have the Load cell spec and the

cable color code (usually you get it with the load cell, or it can be downloaded

from the manufacture web site).

How to test a weighing platform with a few load cells:

1. First stage: Leave all load cells connected to the summing box.

Disconnect the cable from the weighing indicator, connect it to the

LCT100 and perform a test.

2. Expected results for a good scale are as per the following example: If

you have 4 load cells of 1000Ω, 100kg each and 40kg are applied on

the scale than you would expect to see around 250Ω for the input and
