[F 0] Differential pressure check mode, pressure range and display unit
<Differential pressure check mode>
Selected channel is CH1: Differential pressure between CH1-CH2 can be set and displayed.
Selected channel is CH2: Measurement value of CH2 (normal operation) can be set and displayed.
Selected channel is CH3: Differential pressure between CH3-CH4 can be set and displayed.
Selected channel is CH4: Measurement value of CH4 (normal operation) can be set and displayed.

: When differential pressure check mode is selected, the range of the sensor connected to CH1-CH2 and CH3-CH4 should be the
same.
: Initial range setting [rAnG] and unit setting [Unit] and digital filter [FiL] for CH2 and CH4 are not selectable. The operations are based
on the setting for CH1 and CH3.
: Set pressure range during differential pressure check mode is the same as the normal operation mode.
:
During differential pressure check mode, measurement error “[- - -]” is displayed when the applied pressure error ([HHH], [LLL])
occurs in one or both selected channel(s).
Refer to the connection in the table below for connecting the sensor for differential pressure check mode.
Set range can be effectively used by connections below.
