Grain Moisture Meter – Model G939
The “Configuration” mode offers the possibility to make settings or configurations in the
G939 meter. Now, we will describe each one of these functions.
Note that the number shown before each function corresponds to the same shown in
the G939 Menu, this way it is easier to identify in the manual where the explanation of
each function is.
If the Hard Lock key is not connected to the G939 Serial
Port and the access to this function is attempted, the
display will show an error message “Access locked, Use
the Hard Lock” stating the need of the key presence.
If you wish, remove the key after entering the
“Configuration”, there is not a new checking. When you
exit the function, it will be locked again.
G939 settings and Equations can only be changed
with the presence of the Hard Lock key, this ensures
improved security.
This function makes the Date and Time adjustment of the real time clock (RTC). This
value of date and time will be sent in the reports through RS232 Serial Port after the
measurement.
G939 is already delivered with the clock adjusted at the factory, but it may eventually be
readjusted for the Daylight Saving Time.
There is an internal battery that keeps the clock working even when the G939 meter
is disconnected from the outlet. This battery lasts for over 5 years; to have it tested,
just disconnect the G939 meter and see if the clock indicates 00:00:80, if this happens,
contact Gehaka service to replace the battery.
