Wire No
(The number of
sensor element
leads)
Press <M> until this page is appeared on LCD. Then press
<Z> to access the Wire No (programing mode). You can
identify the number of sensor leads by selecting the 2-
Leads (2-L), 3-Leads (3-L) or 4-Leads (4-L) by pressing
<S>. After that, press <Z> until all characters blink. Then
press <M> for the saving new parameter and switching
from programing mode to operation mode.
Calibration Type
(the relation
between input
sensors and output)
Press <M> until this page is appeared on LCD. Then press
<Z> to access the Sensor Calibration Type (programing
mode). You can identify the type of calibration by
pressing <S>. After that, press <Z> until all characters
blink. Then press <M> for the saving new parameter and
switching from programing mode to operation mode.
Sensor Factor
(apply a
proportional factor
to measured value)
Press <M> until this page is appeared on LCD. Then press
<Z> to access the Sensor Factor (programing mode). You
can identify the sensor factor by pressing <S>. After that,
press <Z> until all characters blink. Then press <M> for
the saving new parameter and switching from
programing mode to operation mode.
