Need of Zero/Span Adjustment
1) The zero span adjustment makes adjustment when the fully opened condition(100%) or the fully closed condition(0%) is
reached in an incorrect position.
2) There are two types of adjustments, automatic and manual. Connected to a control motor or the like, the instrument checks and
adjusts the zero side and the span side of the rotating position of the motor shaft. If getting out of a position is found at the time
maintenance/replacement of the control motor, readjustment should be made.
3) Before using the instrument make sure to carry out zero/span adjustment.
4) Before zero/span adjustment, make sure to confirm that all wiring has been carried out correctly.
5) In some cases, erroneous wiring, if any, of terminals R1 and R2 is unable to be checked. You should be very careful to avoid
erroneous wiring.
6) Confirm the direction of revolutions of the motor by the use of the
and
keys in Section 7-2 Manual Operation (2).
Once it is confirmed, change manual operation to automatic. Zero/span adjustment is not possible in manual operation.
Use the
and
keys for switching between the 1-0 zero/span automatic screen and the 1-00 zero/span manual screen and
the
Key for registeration.
