Power Saving Standby Mode
If the luminometer is on but has not been used for 19 minutes, it
will beep every 10 seconds for 1 minute, and then turn off. If any
key is pressed during that time the luminometer will reset the
Standby Mode countdown. The Standby Mode settings can be
changed (see section
3.11
).
To turn the luminometer back on, simply press the button.
2.7
Internal Calibration
When the luminometer is turned on (see section
2.3
), it performs an internal calibration, as the
display counts down from 15 to 0 seconds.
NOTE
: During the calibration sequence, there must
not be a testing device in the luminometer and the
lid must remain closed. If the
icon is shown with the arrow
flashing, open the lid and remove the testing device from the
luminometer. If the
icon is flashing, close the lid. If it is still
flashing, make sure the rubber flap covering the RS232 port is
tucked under the lip and is flat.
TIP
: The button can be pressed at any time to access the set-up
menu options (see section
3
).
When the calibration is complete, the luminometer is ready to
perform a sample measurement.
For details of how to perform a sample
measurement refer to section
4
.
NOTE
: When the luminometer is ready to perform a
measurement, with the lid closed and no testing
device present, the luminometer will automatically
perform a
recalibration
cycle under any of the following
circumstances:
The user presses and holds down the button for 1 second.
The luminometer is used in an environment where the
temperature changes significantly (typically more than +/-5
o
C).
2.8
Low Memory Warning
The luminometer can store up to 2000 test results
in its internal memory. When the memory is more
than 95% full (i.e. less than 100 tests remaining)
the following warning symbol is displayed.
When the memory becomes completely full, no
additional tests can be performed until the memory is either erased
or uploaded to the PC (see sections
3.6
and
5
respectively). Test
can be performed if Save Test is turned off (see section
3.13
)
