This is an HW4 software function and is available only when the HygroLog HL-NT is connected to

a PC running the HW4 software (version 2.3.0 or higher).

11. Warnings and useful tips

Battery Power: when no external AC adapter is connected, use the HW4 software to set the

display to automatically go blank after a specific time interval when there is no keypad activity

or communication over the UART interface.

Set both the display refresh rate and the log interval to the highest values compatible with

your application.

Avoid using a docking station with internal electronics without using an AC adapter.

Do not connect several probes to the HygroLog HL-NT without using an AC adapter.

Do not attempt to charge a regular battery: when using a regular battery, configure the

logger with HW4 so as to disable the internal battery charge function of the logger. Trying to

recharge a regular battery is potentially dangerous.

Date and Time Format: prior to using your logger for the first time, be sure to verify the

following configuration settings: date format (including separator), time format (including

separator) and decimal separator. In order to be able to read log files on a PC, these settings

must be identical to the settings of the PC operating system. If necessary, use HW4 to re-

configure your logger.

Internal Probe (Input 1): for a faster response, use the probe in the extended position.

Compliance with ERES regulatory requirements: Use the HW4 software to disable either

the MENU key or the entire keypad. Disabling the MENU key prevents unauthorized changes

to the configuration of the HygroLog HL-NT and also prevents any probe adjustment.
