The System Setup menu allows the user to customize the user interface, consult the meter information, set the
external serial communication interface and to restore the manufacturer settings.

Accessing System Setup

• Press

 while in 

Measure mode.

• Press

. The system setup options will be displayed

on the LCD.

To access a System Setup option:

• Use

 or 

 to highlight the desired option.

• Press

 to access the selected option.

The following is a detailed description of the System Setup option
screen.

Beeper

This option allows the user to enable or disable the beeper. When the beeper is enabled, a specific beep will
be heard when the reading becomes stable, when an alarm condition is reached,     when pressing a key or if
a wrong key is pressed.
Stability Indicator
When the reading becomes stable, the instrument delivers a medium beep only if this option is ON, along with the
“Stable” indicator on the LCD.
Alarm
If this option is ON, a continuous double beep will be heard each time the set limits in 

Measure mode are

exceeded, along with the “Alarm” indicator on the LCD.
Key Pressed
If this option is ON, a short beep will be heard each time a valid key is pressed.
Wrong Key
If this option is ON, a long beep will be heard when an incorrect key is pressed.

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 feature.

Data can be exported to the most popular spreadsheet programs for further analysis.

HI 4521

 and 

HI 4522

 instruments have two available serial interfaces: RS232 and USB. The desired serial

interface can be selected from the settings window of the 

HI 92000

 software.

If choosing the 

RS232

 serial interface, use the optional Hanna 

HI 920010

 cable connector to connect your

instrument to a PC. Make sure that your instrument is switched off and then plug one connector to the
instrument RS232 socket and the other one to the serial port of your PC.

Note

: Other cables than 

HI 920010

 may use a different configuration. In this case, communication between

instrument and PC may not be possible.

If choosing the 

USB

 serial interface, use a standard USB cable to connect your instrument to the PC.

For both serial interfaces, make sure that the instrument and the 

HI 92000

 software have the same baud rate

and the appropriate communication port.
