Bomb Rinse Tank Controls
Report Rinse Tank Empty: When turned on
the calorimeter will notify the user when it
believes the rinse tank is empty based upon
capacity of tank and number of tests.
Rinse Tank Capacity: Sets the number of tests
available from a full container. If the rinse
timing controls have been changed, then the
value must be changed proportionally.
# Rinses Left: This value provides an estimate
of how many rinses are left in the tank. This
number is simply a counter not an actual mea-
surement of the volume in the tank.
Reset Rinse Tank Counter: Resets the counter
when the rinse tank has been refilled. This
counter must be reset after the rinse tank is
refilled.
Rinse Time: This value establishes the time
that the rinse water solenoid is turned ON for
each rinse cycle. When the rinse water sole-
noid is ON, distilled water from the rinse tank
is pumped, under pressure, into the bomb
cylinder. This rinses the cylinder walls and the
bomb head. These rinsings are then pooled
and collected at the exhaust port of the calo-
rimeter. The factory default value is 2.5s. This
value, along with the # of rinse cycles, deter-
mines the total volume of recovered rinse.
These default values will yield a total of 50 mL
(approx.) of bomb washings.
Rinse Flush Time: This value is used to estab-
lish a time between rinse cycles. During this
time the rinse solenoid is turned OFF. This
off time permits the rinse water to drain out
before the next rinse cycle begins. The factory
default value is 2s.
Clear Time: This time value is used to establish
a post-rinse oxygen filling time for the bomb.
This step is used to clear the lines and valves
of any residual rinse water prior to the next
test. The factory default value is 10s.
# of Rinse Cycles: This value establishes the
number of distinct rinse cycles used to rinse the
bomb. The factory default value is 3 rinse cycles
Note: Rinse Time, Rinse Flush Time, and
Clear Time are input in tenths of a second in
order to enable fine tuning of rinse function.
“Other” Multiplier: Press this key to display the
Other Multiplier dialog box, where the user can
enter a final multiplier to be used when the report-
ing units are set to “Other”.
Calibrate Touchscreen: This key prompts the user
to touch the screen at predefined points in order to
facilitate touch screen calibration. It is important that
a touch screen stylus, rather than a finger, be used
in order to realize an accurate calibration.
LCD Backlight Timeout: The unit is equipped with
an automatic circuit to shut off the backlight when it
is not being used. The back light will shut off if there
is no keyboard activity for the number of seconds
entered. Pressing any key will automatically turn
the back lighting ON. A setting of 0 will keep the
backlight ON at all times.
LCD Backlight Intensity: This key accesses a sub-
menu with a slide control which adjusts the bright-
ness on the LCD display for optimum viewing.
Print Error Messages: When turned ON, all error
messages will be printed on the printer as well as
displayed on the screen. When turned OFF, mes-
sages will only display on the screen.
Language: Steps the Calorimeter through the
installed operating languages.
