12. ZERO ADJUSTMENT MODE

In the measurement mode, the pressure connection (H, L) is open to the

atmosphere and T key is pressed for more than 3 seconds in order to

shift to zero adjustment mode (refer to section 11) for zero point adjust-

ment of the differential pressure sensor.

• If the zero point adjustment is correctly performed, the message "AdJ"

will be displayed for 2 seconds, and the display will return to the meas-

urement mode.

• If zero point correction is performed when the applied pressure is over

±10%F.S., the error message “E-0” will be displayed for 2 seconds, and

the display will return to the measurement mode without completing the

zero point adjustment.

CAUTION: Only perform the zero point correction when both the

H and L ports are open to the atmosphere. If done incorrectly the

accuracy of the device may be effected.
