the name will be changed to “INPUT 1”, for example.
When you change the type of analog channel, it will automatically be “de-calibrated” (i.e., there
will be no calibration set for that channel). When a channel is not calibrated, that channel will
not be captured, even if it is enabled. The channel must be calibrated in order for data
acquisition to occur for that channel. (There is one exception to this rule: if a channel is defined
as type “raw”, it cannot be calibrated, but even so, it is captured if enabled.)
When you change the descriptive name of an analog channel, if the name has been defaulted to
(e.g.) “INPUT 1”, then on the first key press the name will be cleared to allow entry of the new
name.
You may “de-calibrate” (i.e., remove calibration information for ) an analog channel. The primary
use for this would probably be for a temperature-capture channel, where many calibration points
are set. So, for example, if a mistake is made in the calibration for a temperature channel, since
an individual temperature-point cannot be deleted, you must delete all calibration information
for that channel, then re-calibrate.
Don’t worry if you mess up a calibration – you can re-do a calibration at any time.
If a channel is not calibrated, its value will display as “-“.
1.8 Time and Distance Meters
The GPX has two internal time and distance meters. These each keep track of the active time and
distance the vehicle traveled, whenever the GPX is receiving a valid GPS signal.
The two meters are independent of each other, and either may be cleared at any time.
