The 2-
×
-40-character liquid crystal display shows the current instrument set-
tings. You can change the contrast of the display to appear darker or lighter as
desired. Press and hold the
[Shift]
key and then press the up or down arrow on
the
[AutoMix]
key. Pressing the up (
▲
) arrow makes the display lighter; pressing
the down (
▼
) arrow darkens the display.
Keys
Most stand-alone instrument functions can be performed by pressing a single
key; a few others require that you press keys in combination. The functions of the
control panel keys are described below.
[Setup]
Allows you to choose from a group of assay protocols that have been saved in
non-volatile memory (stored by number from 0 through 9). The settings stored
under “0” are factory preset defaults and cannot be modified or deleted. At the
time of shipment, settings 1 through 9 also contain the same preset defaults.
Non-volatile memory is retained even if the instrument is turned off.
[Save]
Stores the instrument settings you have chosen for the assay into memory under a
specific number from 1 through 9 (0 is reserved for the default instrument proto-
col).
[Recall]
Recalls the instrument settings previously stored using the
[Save]
key.
[\ 1 nm]
Selects the measurement wavelength. Pressing the up or down arrow key scrolls up
or down through the available wavelengths, starting at the previous setting. Press-
ing the up (
▲
) or down (
▼
) arrow once increments or decrements the wavelength
shown in the display by 1 nm; pressing and holding either arrow increments or
decrements the wavelength shown in the display by 10 nm until it is released. If
you increment the setting to the highest limit (850 nm) and continue pressing
the up (
▲
) arrow, the display returns to the lowest possible setting (340 nm) and
begins incrementing from there. The inverse is true for decrementing by pressing
the down (
▼
) arrow.
[\1-2 nm]
Selects the reference wavelength. Pressing either the up (
▲
) or down (
▼
) arrow on
this key once increments or decrements the wavelength shown in the display by
1 nm; pressing and holding either arrow key increments or decrements the wave-
length shown in the display by 10 nm until it is released. If you increment the
setting to the highest limit (850 nm) and continue pressing the up (
▲
) arrow, the
display returns to the lowest possible setting (340 nm) and begins incrementing
from there. The inverse is true for decrementing by pressing the down (
▼
) arrow.
