If the flash point has not been detected when the safety cut temperature (expected flash point
+30
o
C(+60
o
F) or 400
o
C(760
o
F)) is reached, the display will be as

, indicating the safety
cut temperature. Then, the heating will stop.

3.4.6 Completion of a Test
WARNING If test cup is still hot after cooling is finished, do not touch
except arm handle without wearing gloves.
Be careful when handling the hot specimen. It may flash or
explode, if you disposed it to waste tank containing waste with
low flash point.
The cooling fan stops (the
COOL
lamp goes off) in 10 minutes (
*3
) after the flame detection. One
cycle of a test is completed at this moment and you can start the next test. When further cooling is
required, press the
COOL
switch. Cooling is available for another 10 minutes (
*3
).
The temperature display (flash point) is held until the
RESET
or
START
switch is pressed.
*3:
Cooling time is adjustable. Also selectable (do cooling or not). For changing
cooling time, consult Tanaka authorized distributor.
3.5 Test by Special (Fast Search) Mode
This mode is used for measuring an approximate flash point of a specimen of unknown expected
flash point. The mode starts the ignition source application (at each 2
o
C(5
o
F)) from the test start.
Other than the test flame application, all the rest of the test procedure is the same as the Normal
mode. The following shows only differences from Normal mode. See Section
3.4.1
to
3.4.6
