Auto calibration
The auto calibration function will perform manual calibrations automatically at user
defined cycle, which is set by operator.
The setting is activated once the [start] button in auto calibration box is pressed.
(Figure 3-15)
(It’s not always necessary that the HGM is communicating with the model HGC303
after these settings have been made.)
An example of a calibration time chart is shown below.
Setting date and time 2001/09/14 18:00
Setting data: Time: 20:00 Interval: 1 day Hold time: 1 hour
The model HGC303 discerns whether a new calibration should be performed or not by
using an RF (response factor) during auto calibration.

CAUTION
(1) Verify that the current time is correct in the [HGC time adjusting] box. [Current]
means the present time, which is being transmitted from the model HGC303.
(2) One measurement data will be used as calibration data. (not average data)
Therefore, set the enough hold time.
(3) Auto calibration will start on the day after the setting date.
(4) Model HGC303 holds the process variables to host control system during [Hold
time].
