No.PS##-OMH0006-C

○Conditions and explanations for auto-shift function

•Keep constant pressure for 10 ms or longer from the close signal of auto-shift input.

•At auto-shift input, [ooo] is displayed for approximate 1 second. Pressure value at that time is memorized

as corrected value [C_5] or [C_3].

•The switch set as auto-shift mode at the time of initial setting operates with the value which applied
corrected value [C_5] or [C_3] to setting value.

•CH1 will operate with auto-shift function.

[n_4].

•CH2 to CH4 will operate with auto-shift function

The operate value of OUT1 applies corrected value [C_3] to the setting value [P_1] and [P_2] or [n_1]
and [n_2].

•Span is 15 ms or less until the switch output starts soon after auto-shift input.

•When corrected measured value exceed the set pressure range with auto-shift input, the value is changed

to be within the range of set pressure.

•When auto-shift function is turned off, corrected value becomes zero.

•When auto-shift function of all channels is turned off, even if auto-shift input is Lo (Non voltage input) does

not show [ooo].

•Corrected value after auto-shift input will vanish when the power is off, and is reset to zero (Initial value)
when the power is off, and is reset to zero (Initial value) when the power is re-supplied.

∗: EEPROM is not used for memory corrected value.
