INTRODUCTION

The data loggers of the series HD208 are compact instruments for monitoring tem-perature, relative humidity (RH) and dew point temperature. Usable in a wide spectrum of applications, are available in various models:

• With 1 channel for temperature only (depending on the model, the sensor can be internal, external fixed or external with cable).
• With 1 channel for temperature and relative humidity (combined probe fixed or with cable).
• With 2 channels for temperature only (one external sensor with cable and one internal sensor).
• With 2 channels: one for temperature and relative humidity (combined probe with cable) and one for temperature only (internal sensor).

All models can be supplied with or without LCD. The logging function is extremely versatile; logging can be started and stopped manually, using the front buttons, or the start and stop date and time of acquisition can be programmed. The delayed start capability allows starting the logging with a configurable delay time after pressing the button for the manual start. For each quantity detected, two configurable alarm thresholds can alert the user if the measure exceeds the configured parameters. The instrument automatically generates, after logging, a PDF report with charts of the variables collected and a CSV file with all measurements logged. The PDF and CSV files can then be copied to the PC via the USB port, without any dedicated software: the instrument is recognized as a USB flash drive.

The basic application software HD35AP-S supplied with the instrument allows the configuration of the instrument, the real-time monitoring of the measurements and the transfer of the acquired data into a database. The connection to the PC does not require any installation of USB drivers, thereby ensuring compatibility with all versions of the Win-dows® operating system. The HD35AP-CFR21 application software option allows the use of security features of the recorded data and configuration of the instrument in response to FDA 21 CFR part 11 recommendations. Powered by a 3.6 V non-rechargeable lithium-thionyl chloride battery (Li-SOCl2). The sensors are pre-calibrated and require no further calibration by the user. If necessary, the user can perform a new calibration using the HD35AP-S application software. All versions can be ACCREDIA certified, upon quote.

INSTALLATION

The case of the instrument is provided with a hole on the back to fix it to a support (screw or hook) on the wall. Insert the head of the support in the lower part of the hole (width 10 mm) and lower the instrument so that the head of the support remains wedged in the upper part of the hole (width 6 mm). Make sure that the instrument cannot accidentally come out from the support.

Alternatively, a fixed installation can be realized, using the optional HD208.13 aluminium flange to be fixed on the back of the instrument case.

BATTERY
The instrument uses a 3.6 V non-rechargeable lithium-thionyl chloride (Li- SOCl2) battery AA size. To connect the battery, or to replace a dead battery with a new one, proceed as follows:

1. Unscrew the 4 screws on the back of the case and remove the back cover.
2. In case of replacement, disconnect the battery connector from the circuit board and replace the battery with a new one of the same type.
3. Connect the battery connector to the circuit board, observing the correct polarity. The connector is equipped with a polarization key that prevents the possibility of a wrong insertion of the connector.
4. Close the case by fixing the 4 rear screws (pay attention to the correct placement of the battery, not to hinder the closing of the case).

The battery symbol at the bottom left of the display lights up when the battery is low; in this case, replace the battery as soon as possible.

CONFIGURATION
The instrument parameters (date/time, logging parameters, alarm thresholds, quantities to be acquired) are configurable by connecting the instrument to a PC and using the HD35AP-S application software (please see the instructions of the software) or, alternatively, a specially designed PDF form included in the HD35AP-S software pack-age (file HD208 configuration.pdf in folder PDF/Language/Config_HD208).

The use of the PDF form must be enabled with HD35AP-S software. For the use of the PDF form, please see the HELP button in the form.

MODELS WITH LCD

In models with LCD, MODE and SCROLL buttons allow viewing a variety of information. With the MODE button (short press) you choose the type of information: measurements, date and time of the instrument, alarm thresholds, start and stop instants of programmed logging, and delay time for the manual start of logging. With the SCROLL button (short press) you navigate through the various fields of the type of information selected (see function diagram shown below). The button operation is cyclical. If you press the SCROLL button when the display shows the last of the quantities available on the display, the instrument does not return immediately to the first quantity but starts to automatically cycle through all the available quantities. Press SCROLL again to return to the permanent display of the first quantity.

If a parameter is not set, the instrument will display dashes.

ALARM SYMBOLS ON DISPLAY
In addition to the alarm LEDs, there are four alarm indications on the display; an arrow lights up in correspondence the alarms 1, 2, 3 and 4 if:

• Alarm 1: the temperature is below the lower threshold configured.
• Alarm 2: the temperature is above the upper threshold configured.
• Alarm 3: the relative humidity is below the lower threshold configured.
• Alarm 4: the relative humidity is above the upper threshold configured.

If the model measures two temperatures: the external sensor (channel 1) and the internal sensor (channel 2), alarms 1 and 2 refer to the temperature measured by the external sensor (channel 1).

ERROR MESSAGES ON DISPLAY
If a detected quantity is in error, the following indications appear on display:

• UFL: the measured value is less than the minimum measurable (Underflow).
• OFL: the measured value is greater than the maximum measurable (Overflow).

LOGGING

The start of logging can be:

• Automatic, by programming the start date and time.
• Manual, by pressing for more than 2 seconds the button START/MODE.
• Delayed: logging does not start immediately when you press the START/MODE button, but after the delay time set.

Logging stop can be automatic, by programming the stop date and time, or manually, by pressing for more than 2 seconds the STOP/Scroll button. The programmed time and the delay time are set using the HD35AP-S software or the PDF form. During logging, the LOG symbol on the display and the LOG LED flash. In case of a delayed start, during the delay time, the DELAY symbol appears on the display, indicating that the instrument is waiting to start logging.

PDF REPORT

At the end of each logging session, the data logger automatically generates a PDF report, which can then be copied to the PC via the USB port of the instrument. When generating the report, the display of the instrument shows PdF.
The report includes the graphs of the detected quantities and information about the logging session: logging start and stop time, logging interval, number of samples acquired, alarm thresholds, minimum, average and maximum of each detected quantity.

The report includes the calculation of the Mean Kinetic Temperature (MKT). The Mean Kinetic Temperature is an evaluation index of the cold chain used in the pharmaceutical field and is calculated according to the Haynes equation as a function of all the temperature measurements acquired during the logging session. The Mean Kinetic Temperature is used to evaluate temperature fluctuations experienced by a biological substance during storage or transport and corresponds to the storage temperature that, if maintained constant, produces on the biological substance the same effects of the actual temperature changes recorded in the period considered (i.e. the duration of the logging). You can set the value of the activation energy, a parameter necessary for the calculation of MKT.

The graphs are shown in grey the areas of alarm (values that exceed the thresholds set). The time required to generate the PDF file depends on the amount of data acquired and can go from a few seconds (if the amount of data acquired is limited) up to about a minute.

Note:
the PDF report is generated with the data stored in the Flash memory; the number of samples in the Flash memory may be less than the number of samples stored in the CSV file (please see the memory capacity in the specifications table).

Note:
if the ambient temperature is below zero or the battery level is low, the PDF report is not generated at the end of the logging session, but when the data logger is connected to the PC. At the end of the logging session, the “CON USB FOR PDF” mes-sage appears on the display.

The generation of the PDF report can be enabled/disabled by using the HD35AP-S application software or by holding the STOP button and then pressing the reset button located on the electronic board (above the battery connector).

CONNECTION TO THE PC

Pull out the protection of the USB output and connect the instrument to the PC by using the cable CP23. If the instrument is not logging, the PC detects it as a simple USB flash drive and appears the list of PDF and CSV files with the reports and the data of the logging sessions.

To transfer data from the internal memory of the instrument in a database on the PC, use the HD35AP-S application software following the online instructions of the software. The HD35AP-S software allows the multi-client connection to the database: it is possible to store the data in a remote database on the local network to which the PC is connected, and the data can be viewed from any PC on the network via the HD35AP-S software. During logging it is possible to connect through the HD35AP-S software and display the measurements in real-time (Monitor), but you cannot copy the PDF and CSV files in the instrument.

The connection to the PC does not require any USB driver installation.
To disconnect the instrument from the PC, use the “Safely Remove Hardware” function provided by the operating system. When the instrument is not connected to the PC, reposition into place the protective cap of the USB output.

Note:
During PDF report generation at the end of a logging session, the instrument does not respond to the PC; wait for the instrument to finish saving the PDF file.

ADVANCED SOFTWARE
The HD35AP-CFR21 option allows, in addition to the features of the basic software, the protection of recorded data and configuration of the instrument in response to FDA 21 CFR part 11 recommendations. In particular, become available:

• The traceability of activities (audit trail) performed with the software; for example, which users connected and what changes were possibly made to the configuration of the instrument.
• The management of users’ access to the instrument configuration and viewing of data in the database. Each user can be assigned a different password for using the software. There are also three levels of access (Administrator, Super-user and standard User); for each level, the allowed operations can be defined.

To activate the advanced mode, the hardware key supplied with the HD35AP-CFR21 option must be connected. The hardware key can be connected to any PC connected to the same local network of the PC in which the HD35AP-S software is installed (please see the instructions provided with the key).
