This manual is valid for instruments with firmware version 2.0x (see MENU - Instrument or check using the ROTRONIC HW4 software, Device Manager). Examples: 2.0a, 2.0b. Changes in the last character of the version number reflect minor changes in the internal software of the instrument that do not affect the manner in which the instrument should be operated. -
Page 4: Compatibility With Previous Models Of Probes And Docking Stations
When equipped with a docking station, the HygroLog HL-NT can be used together with the ROTRONIC HW4 software for Windows based PCs (version 2.3.0 or higher). In addition to providing for the networking of large quantities of data loggers and other instruments, the main... -

Page 8: Power Supply
Note: most models of docking station require the use of an external AC adapter due to the current consumption of the docking station internal electronics. After reconfiguring the HygroLog HL-NT with the ROTRONIC HW4.software, a rechargeable battery (accumulator) can be used instead of a regular battery. Recharging the battery require a docking station and an external AC adapter. -
Page 9: Memory Card
LOG are encoded in binary format so as to prevent data manipulation and can only be read with the ROTRONIC HW4 software. Both types of files can co-exist on the memory card. The memory card can be removed from the logger and transferred to a card reader, a PDA, etc. -

HW4 does not allow any manipulation / alteration of the data and requires a password to log in. Should the file be somehow modified, HW4 will give a warning that the file is not an original.
- Page 12 Using the HW4 software, both a high and a low alarm value can be associated with the humidity, temperature and calculated parameter of each probe input, A hysteresis value can also be entered for each parameter. This value is used for both the low and the high alarm conditions. © 2009-2012; Rotronic AG IN-E-HL-NT-V2_12...

Page 17: Docking Stations For The Hygrolog Hl-Nt
HygroLog HL-NT is meant to be used with one of the available docking stations (UART interface). When installed on a PC, the ROTRONIC HW4 software is used to configure the HygroLog HL-NT, to program its logging function, to download the recorded data and to adjust the probes connected to the logger against a reference environment. - Page 18 Each probe input uses an internal 150 Ohm resistor to convert 4…20 mA to 600…3000 mV (nominal).

Page 30: Eres Regulatory Compliance
In order to comply with ERES regulatory requirements (Electronic Records and Electronic Signatures), the HygroLog HL-NT should be used together with the ROTRONIC HW4 software – Professional Edition (version 2.3.0 or higher). HW4 is designed to keep track of logger configuration changes, programming changes and of any probe adjustment. -
Page 31: Getting Started
HygroLog HL-NT is powered via a docking station. The normal function of the display is to show the most recent measured values, one at a time. The display is also used to navigate the Function Menu of the HygroLog HL-NT. © 2009-2012; Rotronic AG IN-E-HL-NT-V2_12... - Page 32 If the keypad does not work, you should check the configuration of the HygroLog HL-NT with HW4. Disabling the MENU key prevents unauthorized changes to the configuration of the HygroLog HL-NT and also prevents any probe adjustment. Compliance with FDA / GAMP requires the MENU key to be disabled. © 2009-2012; Rotronic AG IN-E-HL-NT-V2_12...
