9.3. Setting of Range Changeover
9.3.1. Setting of range changeover
Range changeover functions include the following two modes.
①
Auto range mode
Changes over all pressure measurable ranges automatically.
②
Range hold mode
Prohibit a range change to the pressure range that is lower than indication, the
BCD output, an analog output (only LIN mode). The pressure measurement
does not influence a set point output function, because it is performed in all
measure.
9.3.2. Setting of range hold
The range hold value is entered in the form of
×
10 .
The settable values are as follows:
GI-M2
GI-D7
GI-N8

When the input of an invalid value, the value is not updated. [

on the segment indicator only in the front panel setting.
The value entered last will be saved from front panel or RS-232C.
9.3.3. Range hold and recorder output
The analog output using range hold for is as follows:
①
LINER

②
Linear outputs in proportio

③
Pseudo-logarithmic mode
Outputs are pseudo-logarithmic in all pressure ranges regardless of the range
hold value.
④
REC-HOLD mode
Outputs are in the REC-HOLD mode regardless of the range hold value.
