Zero/span adjustment
Zero and span are adjustable by apply-
ing an actual pressure.
When pressing <LRV> under display 1
the screen for zero adjustment 2
appears, and that for span adjustment 5
appears when pressing <URV>.
Under display 2 , after applying actual
pressure equal to zero point, press
<ENT> 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 <ENT> 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
<ENT> 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 <ENT> 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 <CL>] 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<CL>] is displayed. In this case, adjustment is required again.
