Display Control
The HERMIT 2000 features a large, easy-to-read LCD (liquid crys-
tal) display. The display has excellent readability even in direct sun-
light; in fact, the more light the better.
The LCD is optimized for
comfortable viewing from
below the plane perpen-
dicular to the display as
shown.
When viewing the display in low ambient lighting
conditions, it may be convenient to use the electro-
luminescent backlight. Press the
BACKLIGHT
key
to turn the backlight on; press it again to turn the backlight off.
Try this while shading the display with the operator’s manual. The
backlight will wash out in normal ambient lighting conditions, mak-
ing it difficult to see.
The backlight will switch off automatically when the HERMIT 2000
goes to sleep.
The POWER SAVE Key
Press the
POWER SAVE
key and release it. The HERMIT 2000 will
blank its display and go to sleep. This action helps to extend battery
life by cutting short the normal 60-second sleep delay.
The READY Display
Press and release any key. The HER-
MIT 2000 will wake and respond with
READY
.
The
READY
prompt is presented whenever the HERMIT 2000 is awake
and ready to accept a program or control key. The
READY
display
shown above indicates that:
• The instrument is idle. No test is running or programmed to
start.
• The HERMIT 2000 is operating on its internal battery pack
and the battery pack is in good condition.
• The instrument is ready for you to press a program or control
key. All other keys will be ignored.
As the operating status of the HERMIT 2000 changes, other infor-
mation is added to the
READY
display.
If the internal battery pack begins to
run low, the low bat indicator will be
displayed.
The
ext pwr
indicator is displayed
when the instrument is operating on
external power.

Battery Life Tip
Use the backlight feature only as necessary. Excessive use
of the backlight will seriously impact battery life. If the
backlight must be used for an extended period, use it
inconjunction with external power.
Battery Life Tip
Make a habit of pressing POWER SAVE at the end of every
keyboard session.

CAUTION
When the low bat indicator appears in the READY display,
the internal battery pack has no more than one month
capacity remaining, even less depending on instrument
usage. If you are caught with low bat during a test, con-
nect to external power if possible. You cannot lose stored
data even if the battery becomes completely drained. Sim-
ply connect to external power, dump your data, and re-
turn the instrument for a battery replacement.
