10. External input
You can select functions to be assigned to four external inputs (External input 1 to
4).
„ External input setting screen
When the user setting is set, each function of the external input 1 to 4 can be set.
Functions that can be set differ for each external input. (When the default is set,
these four screens are skipped.)
Press S / T button on each setting screen to specify functions
Reference
When the same function is selected for multiple external inputs, the
inputs function according to OR operation.
„ Zero shift input
When the zero shift input is set to ON, the internal measurement value (R.V.) is
shifted (offset) to the selected shift target value.

„ Reset input
When the reset input is turned ON while using the hold function, the judgment
value (P.V.) in the held state is canceled and the value becomes [-----].

„ Timing Input
When the timing input is turned ON while using the hold function, the judgment
value (P.V.) is held.

• When Sample hold is set
"Timing Input" (page 15) setting: "Level"
"Timing Input" (page 15) setting: "Edge"
• When Peak hold, Bottom hold or Absolute value hold is set

„ Bank A input/Bank B input
By combining the ON/OFF status of bank A input and bank B input, you can
switch between banks.
z Timing chart
Reference
When the judgment value (P.V.) is held using the hold function, the
judgment value (P.V.) remains held even if the ON/OFF status of bank A
input or bank B input is switched. However, the judgment output will
change according to the HI/LO setting value of the new bank.
