TRANSMITTER /- 5Vcc VERSION
For this version the calibration procedures are the same as the standard version: the values of the
APPROXIMATE ZERO and APPROXIMATE F.S.O. tables.
With this version, the calibration can be made so that the range is:
from 0 to +5V if the instrument is cleared at ange beginning;
from -5V to 0 if cleared at ange end;
from -5V to +5V if cleared in the middle of the range.
TARE ZERO-SETTING:
Make sure that the container is empty and set the tare to zero as follows:
Use the zero fine trimmer for little variations, if it isn't sufficient use the dip-switches of coarse zero to
approach zero display as much as possible, then use the trimmer of fine zero again
.
