Set up Journal Mode
Journal mode is similar to Automatic Datalogging mode where
the operator can set a timed interval between data points being
communicated to the PC.
In Journal Mode the HHC will output the data string at a time
interval set by the user. No command from the PC is needed to
start the Journal output. The Journal mode output is started
and stopped via the user from the keypad of the HHC
Press MENU key
Use DOWN or UP ARROW to highlight “Modes…”
Press ENTER
Use DOWN or UP ARROW to highlight “Communications …”
Press ENTER
Use DOWN or UP ARROW to highlight “Journal/Inquiry…”
Press ENTER
Use DOWN or UP ARROW to highlight “Journal Interval…”
Press ENTER
Display will show “Journal interval”
Note: maximum journal interval is 86400 seconds (24 hours)
Press left and RIGHT ARROWs to select desired numeric
character.
Press UP and DOWN keys to increment values UP or DOWN.
When the desired interval is displayed Press ENTER to save.
*NOTE*
To begin or stop detecting journal data when in Journal/Inquiry
menu use DOWN or UP ARROW to hilight “Journal Start/Stop”.
Press ENTER. When programming, the display will show
“Desired” interval and “Actual” interval. Actual interval may not
match the desired value. The minimum sample rate changes are
based on the number of inputs installed in the base unit. The
sample rate increase 0.1 seconds per input (0.1, 0.2 or 0.3 sec-
onds). The actual interval must be an even multiple of this value.
For example if there are two pressure modules and a voltage
input active, the minimum sample rate is 0.3 seconds or even
multiples of 0.3 seconds. If the desired value entered is 1 second
the actual value will remain 1.2 seconds.

HHC Base Unit Field Calibration
The HHC base unit can be recalibrated and certified in the field.
The procedure allows for the acquisition of “as found” and “as left”
data, and recalibration of the base unit.
Field calibration typically consists of three steps. Step one is to
document the “as found” or pre calibration condition of the HHC.
Step two is to perform the recalibration procedure to adjust coeffi-
cients used by the HHC. Step 3 is to repeat step one to document
the “as left” or post recalibration condition of the HHC.
The procedure details three processes, first obtaining “as found”
and second performing the actual calibration of the HHC, and third
obtaining “as left” data..
