Each data set consists of three (3) lines. The first line
displays the current measurement data as seen on the
instrument display. This line will display the pressure,
flow, temperature or electrical measurement in the
selected units of measure. Engineering units may be
changed from the keypad as outlined in the engineering
unit section of this manual, Section 8.0, while the RS232
interface is in use. In addition, the HHC can be changed
from pressure to flow measurement while the RS232
interface is in use.
The second line displays the minimum and maximum
values stored in memory for the left sensor module since
the last time the memory locations were cleared.
The third line displays the minimum and maximum
values measured by the right sensor since the last time
the minimum and maximum pressure values were
cleared from memory.
In the journal mode the RS232 interface will output the
data as outlined above at a regular interval. The interval
is selected in the RS232 setup procedure and may be
from 1 second to 65,000 seconds.
