There are four modes that specify the content and length of the
information provided during testing.
See page 42 for the status message formats for modes
0, 1, and 2, and page 43 for mode 3.

 Mode 0 —Print mode off. Select this mode when no automatic output
from the HI-1710A is needed; for example, when all output is
specifically requested by the controller. This mode might be chosen in
a fully-automatic test system where the external device requests the
measurement, data gathering, and the zeroing of the meter.
Status messages are transmitted in the same form as in mode 2,
but no message is transmitted by the HI-1710A when the zero
command is received.
 Mode 1 —Prints continuous reading. In this mode the HI-1710A
continually sends the RF reading through the RS-232 serial port. Data
is transmitted at a high rate and can only be used at baud rates of
4800 and above; data is sent at a rate of 45 Hz, the same rate at which
the probe is sampled. The controlling device must be able to receive a
serially-transmitted 4-digit number 45 times a second.
This mode might be used in the laboratory to investigate the
effects of different filter constants and scan rates. The output from
the HI-1710A is a three- or four-digit ASCII string in the format
X.XX or X.XXX.
