Journal Inquiry
Step 10
With the word Journal fl ashing press the
enter key.
ENT
The HHC will respond by displaying the following:
Report Interval
xxxxxxx
Step 11
Using the number keys enter the desired inter-
val, in seconds, between data transmissions. The interval
may be any value from 1 second to 65000 seconds. In
the example below the HHC is being instructed to trans-
mit a set of readings every 600 seconds (10 minutes).
Report Interval
600
Step 12
With the desired time interval displayed press
the enter key.
ENT
The HHC will respond by displaying:
End of message
CrLf Prog
Step 13
Select the desired end of message character.
For data transmission to a screen on a dumb terminal
the CrLf (carriage return/line feed) is the most common
option. If the data output is to be transmitted into a data-
base or spreadsheet program the end of message charac-
ter must be selected in accordance with the requirements
of the application software. Proceed to Step 16 to input a
custom end of message character.
Step 14
To use CrLf as the end of message charac-
ter use the arrow keys to select the text “CrLf”. When
selected the text “CrLf” will fl ash.
End of message
CrLf Prog
Step 15
With the text CrLf fl ashing press the enter key.
ENT
The HHC will return to pressure temperature measure-
ment and will transmit data to the terminal, acquisition
device, computer or recorder as programmed. While
communicating, engineering units may be changed or
the HHC may be changed between basic pressure mea-
surement and fl ow measurement.
Important Note:
Invoking set up functions or dedicated
keypad functions will temporarily suspend the transmis-
sion of data during the setup process. For most functions
data transmission will resume when the set up is com-
plete. However, the RS232 interface must be re-enabled
via the RS232 set up process to re-initiate data transmis-
sion after either automatic data logging or leak detection
functions are activated.
Step 16
To select a programmable end of message
character use the arrow keys to select the text “Prog”.
End of message
CrLf Prog
Step 17
With the text Prog fl ashing press the enter key
ENT
The HHC will respond by displaying:
EOM character
xx.xx
Step 18
Using the number keys enter the decimal code
for the desired end of message character. A list of the
decimal codes for the available ASCII characters can be
found in Appendix B.
Step 19
With the decimal representation of the desired
ASCII character displayed press the enter key.
ENT
The HHC will return to the operation of pressure mea-
surement and will transmit data to the terminal, acquisi-
tion device, computer or recorder as programmed. While
communicating, engineering units may be changed or
the HHC may be changed between basic pressure mea-
surement and fl ow measurement.
Important Note:
Invoking set up functions or dedicated
keypad functions will temporarily suspend the transmis-
sion of data during the setup process. For most functions
data transmission will resume when the set up is com-
plete. However, the RS232 interface must be re-enabled
via the RS232 set up process to re-initiate data transmis-
sion after either automatic data logging or leak detection
functions are activated.
