HD206... / HD226...
HD206.../HD226... and HD207.../HD227... series dataloggers are low-cost, rugged instruments
for a long-term reliable monitoring of temperature and temperature/relative humidity measure-
ments. They are available in different versions: with or without LCD display, with sensors either
inside or outside the instrument housing, or with cable connection. The analysis of logged data is
made using Delta Log2 software for Windows.
The datalogger functions of Start, Stop, Configuration, Data Download and Setting of logging in-
terval are selectable either from keyboard or from a computer. Through a computer, you can define
a password to enable the access to configuration data.
Typical applications are: monitoring of temperature/humidity during transportation, storage of
fresh or frozen foods, fruit, vegetable products and flowers, pharmaceuticals, sensitive and
photo-graphic products, paper as well as laboratory activities in general.
Configuration and data download to a PC or to a printer are very easy: DeltaLog2 dedicated soft-
ware guides the operator step by step.
SIT calibration certificates are available on all versions.
HD207 and HD227 dataloggers with sensor inside the instrument housing are compliant to
the European Standard EN 12830:1999 (S, T, C, D, 1) if operated in conjunction with the
DeltaLog2 application software from version 2.5.

- Page 28 Dump Data It dumps to a PC the data the instrument has stored while operating. A window will appear indi- cating the download progress and the number of logged records. This window will also allow to interrupt the download operation. Clear Dumped Data It clears minidatalogger data dumped to a PC.
- Page 29 D) Tool Menu Set limits It opens a window that allows to set an alarm low limit and an alarm high limit for each channel of the instrument. This option is particularly useful for a faster analysis of data when you are looking for any possible exceeded alarm limit.
- Page 30 Calc Avg It calculates the average value of a group of selected data in a table. To select a group of con- tiguous data, click the first datum and, holding the Shift key down, click the last one. To select a group of non-contiguous data, click the data to be selected holding the Ctrl key down.

Sort Data It sorts through the groups of dumped data when the instrument is in endless loop memory, ac- cording to the date (time, day, week, month, year) or to the logging session.
- Page 32 Enable Emergency Dump When the instrument is in endless loop memory and you start dumping data, only data logged in the last session will be dumped. In particular cases (if, i.e., the previous data had been uninten- tionally deleted or spoiled) it might be necessary to dump the memory whole content. In this case the emergency dump has to be enabled, paying attention, because the operation might over- run other data already present on the PC, which will consequently go lost.

Page 57: Calibration Of The Relative Humidity Probe (Hd206-2 And Hd226-2 Only)
Calibration of the Relative Humidity Probe (HD206-2 and HD226-2 only) In the HD206-2 and HD226-2 minidatalogger models, operating with a combined external probe, the user can calibrate the humidity probe. To carry out this operation, you need DeltaLog2 program that guides the user step-by-step. - Page 58 5. If the instrument setup has been protected by a password (Lock Program), you have to unlock it before going on. 6. Click Calibration in the Option menu: 7. Enter CAL password (capital letters) and confirm. Select RH and confirm with OK. In the next window, select the first calibration point at 75%RH and press OK.
- Page 59 8. Loosen the sensor protection at the top of the probe. 9. Replace it, with the perforated cap (screw it carefully) and its threaded metal ring (different measures are available according to the different kinds of probe), paying attention that it is well positioned in the base.
- Page 60 15. Select 33%RH in the next window. 16. Take out the probe from the container with the 75%RH solution and close it with its lid, open the container with the 33%RH saturated solution. Check that inside the measuring chamber there are drops of solution: if any, blot them with paper.
- Page 61 17. Insert the probe in the container, paying attention that the cap with the probe is in the base. The measuring chamber has to be perfectly closed, otherwise it won’t reach saturation. 18. Wait 30 minutes, at least and press OK to confirm. 19.
- Page 62 Important Notes: 1. Do not touch the RH sensor with your hands. 2. The base of the sensor is made of alumina, thus it can easily break. 3. During the whole calibration cycle, operate at constant temperature as much as possible; nor- mally, plastic materials have a poor heat conduction, thus they take some time before they reach a thermal equilibrium.
