Excitation trimming procedure
For load cells with matched outputs, shortcut the potentiometers by soldering bridges J1, J2, J3, J4.
First adjustment with reference weight:
1.
Turn the potentiometers fully clockwise for each load cell so that the potentiometer resistance is as
low as possible.
2.
Lay your reference weight at one corner of your weighing system and note the result of the
weighing indicator.
Repeat this operation for each corner.
3.
Spot the corner with the lowest output.
Load successively each corner with the same reference weight and adjust at each step the
potentiometer to match the lowest output corner value.
4.
The load cells outputs are now matched.
Then proceed to normal zero and gain adjustment of the weighing indicator.
Optional overvoltage protection
Corner balancing potentiometer
Additional resistor for special use* (not supplied)
* cut strip conductor before insertion
