9.6.Changeover of Analog Output
Analog output of the measurement pressure can choose three kinds (four kinds) of
follows.
Voltage values on order of several mV are low in accuracy because the recorder output
is 12-bit DAC.
Eeach-digit linear

9.6.1.Setting of analog mode
The analog mode is set in the form of LOG, LIN or REC-HOLD HOL-.
Inputs can be set from the front panel or through the communication (RS-232C).
REC-HOLD can be turned ON/OFF from an external I/O connector.
The value that can set with the REC - HOLD mode as follows.
－０
～
－８
－１
～
－７
－１
～
－９
Selecting the sensitive factor. When it was input appointment or the sensitivity setup
anything other than N2 of the sensitivity factor, the above setting range changes.
When the input of an invalid value, the value is not updated. [

] is displayed
on the segment indicator only in the front panel setting.
The value entered last will be saved from front panel or RS-232C.
REC - HOLD setting from external IO (GI-M2 / GI-D7)
While it is input by IO, it is set by REC-HOLD.
The input cancellation back returns to setting just before that.
9.6.2.Measurement value output in each status
Table. 9-2 gives the measurement value output status in various statuses that can
occur in measurement.
