3.5 Scheduling
The main instrument control screen allows you to configure automatic scheduling.
3.5.1 Automatic Interrogation Schedule
iChart can be configured to automatically interrogate devices and retrieve data on a user-defined
schedule. Set an Interrogation Schedule by clicking the Schedule button on the main
instrument control screen.
iChart will interrogate the device on
the days indicated. Place a check in
the box for the days you wish to
retrieve data. To interrogate the
sensor every day of the week, select
each box as shown in the screenshot.
iChart will interrogate the device one
time during the interval specified in
the Every ? Minutes field. For
example, if this field is set to 60
minutes, iChart will interrogate the
device once an hour.
iChart can be prevented from interrogating the device outside the times indicated in the Between
? and ? fields. When these fields are left at their default values iChart will interrogate the device
during all hours of the day. iChart will only interrogate between the times specified in these
fields.
If you would only like to interrogate at specific times throughout the day, click the At field. Up to
four specific times can be set in the At field. If a time is set in one of these fields, iChart will only
interrogate the device at that time.
Some sensors (ie. multi-parameter water quality sondes) require a certain amount of warm-up
time before taking measurements. Enter an Offset (in seconds) in this field to force iChart to
wait for a period of time before interrogating the device.
To disable automatic interrogation, uncheck the box next to Enable. This box is checked by
default.
