Function Details
J
Power-saving mode (F80)
Power-saving mode can be selected.
It shifts to the power-saving mode without button operation for 30
seconds. It is set to the normal mode (Power-saving mode is OFF.)
when ex-factory. (Decimal points and operation indicator light (only
when the switch output is turned ON.) blink in the power-saving
mode.)
K
Setting of secret code (F81)
Users can select whether a secret code must be entered to release
key lock. At the time of shipment from the factory, it is set such that
the secret code is not required.
L
Auto-shift function (F5)
When there are large fluctuations in the supply pressure, the switch
may fail to operate correctly. The auto-shift function compensates
such supply pressure fluctuations. It measures the pressure at the
time of auto-shift signal input and uses it as the reference pressure
to correct the set-value on the switch.

Auto-shift zero
The basic function of auto-shift zero is the same as the function for
auto-shift. Also, it corrects values on the display, based on a pres-
sure value of " ", when the auto-shift is selected.
