1 INTRODUCTION The data loggers of the series HD208 are compact instruments for monitoring temperature, 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).
2 DESCRIPTION 1. 2. 3. LCD. POWER LED: briefly flashes every 10 seconds to indicate that the instrument is powered. It is steady on if the instrument is connected to the PC. LOG LED: briefly flashes three times when logging starts and stops, and once every 10 seconds during logging. 4. ALARM LED: briefly flashes every 10 seconds if any of the measured quantities is in alarm. 5. Temperature or temperature/RH fixed probe (HD208…TV). 6. M12 connector for probes with cable (HD208…TC). 7.
3 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. Fixing hole Alternatively, a fixed installation can be realized, using the optional HD208.
3.1 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.
4 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, 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 buttons operation is cyclical.
ALARM SYMBOLS ON DISPLAY In addition to the alarm LEDs, there are four alarm indications on the display; an arrow lights up in correspondence of the alarms 1, 2, 3 and 4 if: • Alarm • Alarm • Alarm • Alarm 1: 2: 3: 4: the temperature is below the lower threshold configured. the temperature is above the upper threshold configured. the relative humidity is below the lower threshold configured. the relative humidity is above the upper threshold configured.
5 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.
6 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.
7 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. In order to transfer data from the internal memory of the instrument in a database in the PC, use the HD35AP-S application software following the on-line instructions of the software.
