MODE 1 In mode 1, the HI-1710 continually sends the
RF reading through the RS-232 serial port. This
mode transmits data at a high rate and can only
be used at baud rates of 4800 and above. The
instrument sends data 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. Mode 1 might be used in the
laboratory to investigate the effects of different
filter constants and scan rates. The output
from the HI-1710 in mode 1 is a four digit
ASCII string with the form X.XXX.
MODE 2 Mode 2 is the power - on default mode. In this
mode the HI-1710 sends a preformatted report
through the RS-232 serial port each time the
instrument is zeroed. This format is most useful
when using the Peak Hold mode. With this
configuration, a serial input printer setup to
print adhesive backed labels can be connected
to the RS-232 serial port of the HI-1710. After
scanning an oven, the meter is zeroed. On
zeroing, a ticket is printed with the maximum
leakage observed as well as several system test
parameters. The output is formatted for a
standard 15/16 x 3 inch label. Line feed (LF)
characters are transmitted following the
formatted data to advance one additional label
space with each formatted output. By printing
the report on every other label, the labels can
be removed from the backing more
conveniently.
