1. GENERAL CHARACTERISTICS The HD32.8.8 and HD32.8.16 are two dataloggers for thermocouples that can capture, log and then send to a PC or serial printer the data coming from the 8 or 16 thermocouples. The instruments can work with thermocouple of type K, J, T, N, R, S, B or E. During the measuring phase, the connected probes must be of the same type.
2. KEYBOARD AND DISPLAY DESCRIPTION The user interface consist of a backlit LCD display and the power-on, function, and setting keys. Turn the instrument on and off with the ON/OFF key. When you turn the instrument on, the logo and model will be displayed for a few seconds, and then the main display. In this phase, the instrument detects the inputs where the probes are connected and the unused inputs.
2.1 THE DISPLAY The HD32.8 standard display is divided in two areas: The first area displays, from top to bottom, the battery’s charge status and the current time, the type of selected thermocouple, and the temperatures measured by the probes connected to the inputs. The bottom line displays the options that can be activated using the F1, F2 and F3 keys. Please see the SHIFT FNC key in the following paragraph.
SHIFT FUNCTION key It activates the Shortcut window. A drop-down menu opens as in the figure: The black background item is the active item. To select another item, use the ▲▼ arrows and confirm with ENTER. F1, F2, F3 keys These are “function keys”: They activate the function in the lower line of the display (indicated by the arrow in the figure); the function, enabled by SHIFT FNC, is selected and displayed in “reverse” (e.g. in the figure the “°C” function is enabled).
MEM key It allows to start and end a “logging” session (data recording); the data logging interval must be set in the menu. PRINT key It allows direct printing of the data via the serial port; the data printing interval must be set in the menu. Arrow keys Allow navigation through the menus, selection of the type of thermocouple, and choice of the inputs to be displayed. During measurement, you can select the type of thermocouple using the ▲▼ arrows.
3. OPERATION Connect the probes to the inputs located in the lower part of the instrument, and turn the HD32.8 datalogger on with the key. Using the ▲▼ arrows, select the type of thermocouple used (Tc type). On the display you will see the values measured by the first four connected probes. To view the other probes, use the ◄► arrows. If a probe is disconnected when the instrument is on, the value on the display is replaced by a series of dashes: Reconnect the probe to view the new data.
3.2 THE MAXIMUM, MINIMUM AND AVERAGE VALUES OF THE CAPTURED QUANTITIES In order to display the maximum, minimum and average values of the measured quantities, proceed as follows: 1. Use SHIFT FNC to open the drop-down menu; 2. Use the arrows ▲▼ to select “data”; 3. Confirm by pressing ENTER: The selected quantity is displayed in the central line of the display; 4. The three items max (maximum), min (minimum) and avg (average) are shown in the bottom line of the display using F1 or F2.
During logging, the LOG indication is displayed, the battery symbol blinks and a beep is issued each time a logging occurs. To end the logging, press MEM again. The instrument can turn off during logging between one capture and the next: The function is controlled by the Self_shut_off_Mode menu parameter.

5. PROBES AND MEASUREMENTS You can connect the thermocouple temperature probes of type K, J, T, N, R, S, B and E to the HD32.8.8 and HD32.8.16 dataloggers. The selection is done using the ▲▼ arrows (see chapter 3. OPERATION). The contacts of the thermocouple probe connector are polarized. They must be inserted on the standard miniature socket located on the instrument in the correct direction. These probe positive pole is usually marked with a "+" sign, as shown in the following drawing.
The temperature measured by immersion is carried out by inserting the probe in the liquid where you wish to perform the measurement; the hot junction is housed in the end part of the probe. In the temperature measured by penetration the probe tip must be inserted into the material; the hot junction is housed in the end part of the probe. NOTE: When measuring the temperature on frozen blocks it is convenient to use a mechanical tool to bore a cavity in which to insert the tip probe.
6. INSTRUMENT SIGNALS AND FAULTS The following table lists the instrument indications, the errors and the information supplied to the user. Display indication Explanation ----- This appears if the probe, already detected during turn on, is disconnected or faulty. Over Overflow appears when the probe detects a higher value than expected measurement range for that type of thermocouple.
7. BATTERY SYMBOL AND BATTERY REPLACEMENT, MAINS POWER SUPPLY The battery symbol on the display constantly shows the battery charge status. To the extent that batteries have discharged, the symbol “empties”. When the charge decreases still further it starts blinking. In this case, batteries should be replaced as soon as possible. If you continue to use it, the instrument can no longer ensure correct measurement. Data stored on memory are maintained even without power supply.
The external power supply connector has an external diameter of 5.5mm and an internal diameter of 2.1mm. Warning: The power supply cannot be used as a battery charger. If the instrument is connected to the external power supply, the [~] symbol is displayed instead of the battery symbol. Malfunctioning upon turning on, after battery replacement After replacing the batteries, the instrument may not restart correctly; in this case, repeat the operation.
9. SERIAL INTERFACE AND USB The HD32.8 is fitted with an electrically isolated RS-232C serial interface, and an USB 2.0 interface. Optionally, we can supply a serial cable with sub D 9-pole female connectors (code 9CPRS232) or a cable with USB 2.0 connectors (code CP22). The USB connection requires the previous installation of a driver contained in the DeltaLog9 CDROM. Install the driver before connecting the USB cable to the PC (please see the documentation provided with DeltaLog9 CD-ROM).

The number, and storage start date and time are displayed. (nn= hexadecimal number 00-63).
10. STORING AND TRANSFERRING DATA TO A PC The HD32.8 instrument can be connected to a personal computer via an RS232C serial port or USB port, and exchange data and information through the Deltalog9 software (vers. 3.0 and later) running in a Windows operating environment. It is possible to print the measured values on an 80 column printer (PRINT key) or store them in the internal memory using the Logging function (MEM key). If necessary, the data stored in the memory can be transferred later to a PC. 10.
Number of connected probes Number of samples that can be stored 13 14 15 16 56000 56000 48000 48000 The time required to fill the memory depends on the number of connected probes and the selected logging interval. The following tables report this time, in the format days:hours:minutes:seconds.
10.1.2 The Erase function: clearing the memory To clear the memory use the Erase Log function (see par. “4.2.5 Log File Manager”). The instrument starts clearing the internal memory; at the end of the operation, it goes back to normal display. NOTES: • Data transfer does not cause the memory to be erased: The operation can be repeated as many times as required. • The stored data remain in the memory independently of the battery charge conditions.
11. CONNECTION TO A PC The HD32.8 is fitted with two ports for connecting the instrument to the PC: - RS232C serial port with null modem cable code 9CPRS232. The cable has two sub D 9-pole female connectors. - USB 2.0 port with the cable code CP22. The cable has a USB type A connector for PC connection and a USB type B connector for connection to the instrument. The instrument is supplied with the DeltaLog9 software (vers. 3.0 and later).
