Press M button and return the applied pressure to the
atmospheric pressure and try zero-point adjustment again.
Please contact us. Please use a regulated DC power

If there is any possibility that the sensor may become wet with oil or water, which may
enter the case through the air intake, connect a silicon tube, or similar, to the intake
and position the end of the tube in a suitably safe place. Be sure not to bend the tube
or block the end of the tube.

Pressing the and buttons simultaneously in the Operations Mode
displays on the screen. One second later this change to than
the and buttons are released.（If the pressure port is opened to
the atmosphere.）
Note:You have to adjust Zero under open air condition.
Otherwise you can be seen E‐2 error as you adjusted Zero with residual pressure.
