Data Recording
Data recording function is always on and collects data automatically into
the memory of the device. If the optional data logger module is installed,
the transmitter uses it automatically. Recorded data does not disappear
from the memory when the power is switched off. Collected data can be
observed in a form of a graph in the graphical view of the display or it
can be listed out by using the serial line or MI70 Link program.
Selecting Data Recording Quantities
If the device is provided with the optional display, the recorded quantities
are always those selected for the display. Up to three quantities can be
recorded at a time. See section Changing Quantities and Units on page 97
for instructions on how to select the display quantities with the keypad.
DSEL
Use the serial line command DSEL [xxx] to select the quantities to be
recorded if the transmitter is not equipped with display/keypad.
You may also dump the logged data to the serial line in numeric form
with the following commands.
Syntax: DSEL [xxx]
where
xxx = Data recording quantity. See Table 5 on page 20 for available
output quantities.
Issue the command without parameters and press Enter to display the
current recording parameters.
Example:
