operation.

Note

: If the time is changed with more than one hour before last pH/ISE calibration, a pop-up warning

will appear on the LCD, notifying the user that a date/time conflict has occurred and some
time-dependent modes could work improperly (e.g.

Measure

, GLP, Log).

LCD Setup

This option allows the user to set the

Contrast

, the

Backlight

of the LCD and the

Backlight Saver

. The Contrast

parameter can be adjusted within 7 steps, while the Backlight parameter within 8 steps. The Backlight Saver can
be set from 1 to 60 minutes or it can be OFF (disabled). All the changes are visible on the LCD for each parameter.

Note

: If the instrument backlight turns off after the set period of time, press any key to turn it back on.

To set the LCD Setup:

• Press

while in

Measure

mode.

• Press

• Use

to select the LCD Setup option.

• Press

and use

key to highlight the desired

parameter.

• Use

to adjust the contrast / backlight or to

set the desired backlight saver time.

• Press

to confirm the modified options and return to the

System Setup menu.

PC INTERFACE

Data transmission from the instrument to the PC can be done with the

HI 92000

Windows

compatible

software (optional).

HI 92000

also offers graphing and on-line help features.

Data logged on the

HI 5221

and

HI 5222

meters can be exported to the most popular spreadsheet programs

for further analysis.

HI 5221

and

HI 5222

instruments have an USB interface available.

Use a standard USB cable to connect your instrument to the PC.
Make sure that the instrument and the

HI 92000

software have the same baud rate and the appropriate

communication port.
The PC software may also be used for real time logging.

To delete lots

• Press

while in

Log Recall

mode.

• Press

to access delete or delete all

mode. Otherwise, press

to return to

Log Recall

view

mode.

• After selecting one of the deleting modes, use

to select one lot and then press

to delete the selected lot or all lots. The “

Please wait...

”

message will be displayed on the LCD until the selected lot or
all lots are deleted.

• Press

and then press

to exit deleting mode

and return to

Log Recall

view mode.

• Press

to exit

Log Recall

mode and return to

Measure

mode.

Note

: Logged lots should also be deleted whenever “
