Zero/span adjustment
Zero and span are adjustable by apply-
ing an actual pressure.
When pressing under display 1
the screen for zero adjustment 2
appears, and that for span adjustment 5
appears when pressing .
Under display 2 , after applying actual
pressure equal to zero point, press
two times. Zero adjustment will
be over.
When adjustment is made at any point
other than zero, input the pressure value
at that point at the display of 2 , then
press the key at the display of 3
while applying a corresponding pres-
sure to the transmitter.
Under display 5 , after applying actual
pressure equal to desired span, press
two times. Span adjustment
will be over.
When adjustment is made at any point
other than span, input the pressure value
at that point at the display of 5 , then
press the key at the display of 6
while applying a corresponding pres-
sure to the transmitter.
Press LRV or URV at display of 1 .
When the following is displayed, it means that calibration can not be made because
Menu No. H: LINEARIZE is effective. In this case, set INVALID on the panel of
No. H: LINEARIZE.
1. Span adjustment should be performed after zero adjustment is completed.
2. When the actual input exceeds the adjustable range, [NOT CALB ] is
displayed.
In this case, adjustment is required again.
Adjustable range
Zero adjustment: Within ±40% of maximum span
Span adjustment: Within ±20% of calibrated span
3. When the adjustment point does not meet the following condition,
[SETTING ERR] is displayed. In this case, adjustment is required again.
