2.4 “Push-to-Read” Display Lock
2.5 Working with HachLink™
HachLink 2000 software, version 2.0 or higher, may be used with an DR/2400
Portable Spectrophotometer that is set up to communicate with a computer
(see Communications with a Printer or Computer). Earlier versions of HachLink do
not recognize the DR/2400.
To ensure accurate data transfer, make sure that the serial port settings on the
DR/2400 match the settings in HachLink. Select
Instrument Setup, Computer &
Printer
, Computer then Setup. Selecting Default Setup will match the DR/2400
defaults to those of HachLink.
Note: To turn “Push-to-Read” Display Lock off from within a measurement screen,
touch the display lock icon. Set the Display Lock setting as desired.
Note: In the off setting, the instrument provides constant power to both its display
and its light sources. It is recommended that the “Push-to-Read” Display Lock be
off only when the instrument is operating under external power. This will prolong
battery life.
This feature allows the operator to select between “Push-to-Read”
and continuous display modes. The default setting is
“Push-to-Read” on. In this mode, the “Push-to-Read”
Display Lock
is on, and a padlock icon will appear on the screen.
When the Display Lock is turned off and the instrument is in
continuous read mode, an hourglass may appear in the upper left
corner of the screen. This indicates that the instrument is still
processing a reading. When the hourglass disappears, the
measurement is complete and the results may be recorded.
