How to adjust ESD142 amplifier
The ESD142 amplifier amplifies the load sensor signal coming from a strain-gauge
type of load sensor to the suitable voltage level for the CU1.

ADJUSTMENT WITH THE RATED LOAD OF THE HOIST
NO LOAD ON THE HOOK:
a Check that there is no load on the hook.
b Adjust the trimmer 'ZERO' to counterclockwise until the light '0%' goes on.
c Adjust the trimmer 'ZERO' back to clockwise until the light '0%' goes off.
Now the output signal should be about 4 VDC - it can be measured
between the terminals 1 and 3.

d Lift up the rated load of the hoist.
e Adjust the trimmer 'GAIN' clockwise until the light '100%' goes on.
f Adjust the trimmer 'GAIN' counterclockwise until the light '100%' goes
off. Now the output signal should be about 6 VDC - it can be measured
between the terminals 1 and 3.
