After which the display will blank. If an external power source
is connected at the time, the battery will continue to charge
while the display is blank. If a sampling program was running
or in process at the time of power down the system will
continue to run the program. The display panel will show a
message when the unit starts to take a sample and show
the time until the next sample is to be taken. The display will
remain active for an additional 5-10 seconds before returning
to a powered down state.
If the display panel is not active, press the 0-1/STATUS key

3. Automatic Battery Charging: System will automatically
charge the internal battery any time an external power source
such as the AC/DC Universal Power Supply/Converter or
Automotive Power Adapter is plugged into the EXT PWR IN
receptacle. The rate at which the internal battery is charged
will vary with other system operations. Once the battery is
fully charged, the integral battery charging circuit will place
the battery on a floating or maintenance charge to maintain
the battery in a fully charged state.
4. Automatic Purging: The system will automatically purge
the sample intake line prior to the taking of any sample or the
occurrence of a rinse cycle. This is to ensure that the sample
inlet line is free of any obstructions or debris.
5. Glow-In-Dark Keypad: The keypad is printed with
phosphorescent pigments. These pigments will glow for up
to 20 minutes if exposed to ultraviolet radiation from the sun
or a krypton flashlight. This feature is helpful in low ambient
light conditions. The LCD display is backlightable and when
used with keys that glow in the dark, this lessens the need for
external lighting in dim and dark areas.
