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.
The probes position is detected during turn on: The probes are displayed in sequence according to
the same order of connection: First, the group A ones, then group B, etc.
The communication with the PC occurs through a multi-standard serial port RS232 or an automatic
detection USB 2.0. The memorization and printing interval, the logging start and end date, and the
communication parameters can be configured using the menu.
The captured data can be displayed on the PC using the DeltaLog9 software (vers. 3.0 and later).
Through the RS232 serial port, you can transfer the data in real time to an 80 column serial printer.
NOTE: The set capture and print intervals are valid for all the probes.
Other user selectable/settable parameters are:
• The units of measurement for the displayed temperature quantities: °C, °F, °K.
• The system date and time
• The display of the maximum, minimum, and average statistic parameters.
• The relative value REL.
• The data transfer speed via the serial RS232 port.
• The setting, enabling and disabling of the password that locks the keyboard.
The instrument can store up to 64 LOG sessions (data capture) in two modes:
• Automatic: Setting the automatic start and stop dates;
• Manual: Pressing MEM to start and end the data capture session.
The flash memory has a total capacity of 800,000 recordings divided amongst all existing inputs.
The memory space can be handled in two modes:
• When the available memory is full, the collected data are overwritten starting from the
oldest o nes (circular memory),
• The recording is stopped when the available memory is full.

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.
The probes are displayed in groups of four, according to the order of the connectors from left to
right: From input A1 to input B4 in the HD32.8.8 model, and from input A1 to input D4 in the
HD32.8.16 model. The unused inputs are not shown in the list.
If you have more than four probes connected at the same time, use the ◄► arrows to move from
one group to the other.
If a probe is disconnected when the instrument is on, the measurement indication is replaced by
some dashes “-----”, as in the following example.
Connect the probes again to restore the normal view.

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 user can choose the unit of measurement for display, printing and logging among the allowed
ones: °C, °F or °K.
All used probes must be the same type of thermocouple:
VTRAP32K
A tripod, code VTRAP32, is available for the
measurements. Adjustable height up to 1.50
meters, complete with head that can host up to 6
measurement probes. The same tripod can be
used to support the measurement instrument
during data capture.
The arms fitted with suitable clamps for the
measurement probes can be inserted in the head,
code HD3218K.
The VTRAP32K kit is composed of a tripod,
code VTRAP32, and 5 arms, code HD3218K.
The instrument is supplied with a belt that is
fastened to the two pull buttons on the instrument
side. Using this belt, the instrument can be
hanged on a hook or worn around the neck. Code
HD32CS.
5.1 TEMPERATURE MEASUREMENT
In all versions the thermocouple hot junction is housed in the end part of the probe.
The response time for the measurement of the temperature in air is greatly reduced if the air is
moving. If the air is st ill, stir the probe. The response times are longer than those for liquid
measurements.
- 30 -
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.
In order to perform a correct contact measurement, the measurement surface must be even and
smooth, and the probe must be perpendicular to the measurement plane.
So as to obtain the correct measurement, the insertion of a drop of oil or heat-conductive
paste between the surface and the probe is useful (do not use water or solvents). This
improves the response time and the measurement accuracy.
5.2 WARNINGS, CARE AND MAINTENANCE OF THE PROBES
• Do not expose the probes to gases or liquids that could corrode the material of the probe. Clean
the probes carefully after each measurement.
• Do not bend the probe connectors or force them upward or downward.
• Comply with the correct polarity of the probes.
• Do not bend or force the contacts when inserting the probe connector into the instrument.
• Do not bend, deform or drop the probes, as this could cause irreparable damage.
• Always select the most suitable probe for your application.
• To obtain reliable measurements, temperature variations that are too rapid must be avoided.
• The thermocouple could be non-insulated from its external casing. In this case, be very
careful not to come into contact with live parts (above 48V). This could be extremely
dangerous for the instrument as well as for the operator, who could be electrocuted.
• Avoid taking measurements in presence of high frequency sources, microwave ovens or large
magnetic fields; results may not be very reliable.
• The instrument is water resistant, but should not be immersed in water. Should the instrument
fall into the water, check for any water infiltration.
• For cleaning, use only detergents suitable to the different types of probes and instrument parts.
The thermocouple hot junction can be insulated or non-insulated from the probe’s earth. The probe
response time is faster in the thermocouples with an earthed junction.
The thermocouple insulation decreases with the temperature increase.

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. When the symbol is completely
empty, the instrument shuts off.
The battery symbol becomes [~] when the external power supply is connected.
To replace the batteries, proceed as follows:
1. Switch the instrument off;
2. Disconnect the external power supply, if connected;
3. Unscrew the battery cover screw counter clockwise and take out the battery holder; Do not pull
the battery connection wires as they could break;
4. Replace the batteries (4 1.5V alkaline C-BABY batteries). Check that the battery polarity
matches the indication on the battery holder;
5. Replace the battery holder and fasten the cover’s screw clockwise.
6. Update the clock.
The instrument can be powered by the mains using, for example, the stabilized power supply
SWD10 input 100÷240Vac output 12Vdc – 1A.
The power supply positive (pole) must be connected to the central pin.
- 33 -
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.
After disconnecting the batteries, wait a few minutes in order to allow circuit condensers to
discharge completely; then reinsert the batteries.
7.1 WARNINGS ABOUT BATTERY USE
• Batteries should be removed when the instrument is not used for an extended time.
• Flat batteries must be replaced immediately.
• Avoid loss of liquid from batteries.
• Use waterproof and good-quality batteries, if possible alkaline. Sometimes on the market, it
is possible to find new batteries with an insufficient charge capacity.
8. INSTRUMENT STORAGE
Instrument storage conditions:
• Temperature: -25…+65°C.
• Humidity: less than 90% RH without condensation.
• During storage avoid locations where:
• humidity is high;
• the instrument may be exposed to direct sunlight;
• the instrument may be exposed to a source of high temperature;
• the instrument may be exposed to strong vibrations;

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).
Standard parameters of the instrument RS232 serial transmission are:
• Baud rate 38400 baud
• Parity None
• N. bit 8
• Stop bit 1
• Protocol Xon/Xoff
It is possible to change the RS232C serial port baud rate by setting the “Baud Rate” parameter in
the menu (please see par. “4.3.1 The Baud Rate”). The possible values are: 38400, 19200, 9600,
4800, 2400, 1200. The other transmission parameters are fixed. To send the data to an 80 column
printer with serial input, check the maximum baud rate that can be set on the printer.
The USB 2.0 connection does not require the setting of parameters.
The selection of the port is carried out directly by the instrument: If the USB port is
connected to a PC, the RS232 serial port is automatically disabled and vice versa.
The instruments are provided with a complete set of commands and data queries to be sent via the
PC.
All the commands transferred to the instrument must have the following structure:
XXCR where: XX is the command code and CR is the Carriage Return (ASCII 0D)
The XX command characters are exclusively upper case characters. Once a correct command is
entered, the instrument responds with “&”; when any wrong combination of characters is entered,
the instrument responds with “?”.
The instrument response strings end with the sending of the CR command (Carriage Return) and LF
(Line Feed).
Before sending commands to the instrument via the serial port, locking the keyboard to avoid
functioning conflicts is recommended: Use the P0 command. When complete, restore the keyboard
with the P1 command.

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.
10.1 THE LOGGING FUNCTION
The Logging function allows recording of the measurements registered by the probe connected to
the inputs. The time interval between two consecutive measurements can be set from 2 seconds to 1
hour. The logging starts by pressing the MEM key and ends by pressing the same key again: The
data memorized in this way form a continuous block of data.
See the description of the menu items on chapter “4. MAIN MENU”.
If the automatic turning off option between two recordings (see par. “4.2.2 Self Shut-off mode”) is
enabled, upon pressing the MEM key the instrument logs the first data and turns off. 15 seconds
before the next logging instant, it turns on again to capture the new sample, and then turns off.
The data stored in the memory can be transferred to a PC using the DeltaLog9 software (vers. 3.0
and later) or using the instrument File Manager (see par. “4.2.5 Log File Manager”). During data
transfer the display shows the message DUMP; to stop the data transfer press ESC on the
instrument or on the PC.
If during a logging session the batteries have discharged, the instrument stops recording and shuts
off. The data downloaded on the PC will indicate the logging interruption due to lack of power.
If the instrument is powered only by the mains and, during a logging session, there is a mains power
failure, the last record could be stored incorrectly.
During a logging session, we recommend to attach a charged battery pack and connect the external
power supply: This way, in case of a mains power failure, the batteries continue to power the
instrument.
10.1.1 Storage capacity
The storage capacity varies according to the number of probes connected to the instrument inputs.
The following table reports the number of samples that can be stored according to the number of
connected probes:

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.
• In order to print the data to a parallel interface printer, you must use a parallel-serial adaptor (not
supplied).
• The direct connection between instrument and printer via a USB connector does not work.
• Some keys are disabled during logging. The following keys are enabled: MEM, SETUP, TIME,
ENTER and ESC.
10.2 THE PRINT FUNCTION
Press PRINT to send the measured data directly to the RS232 ports, in real time. The printed data
units of measurements are the same as those used on the display. The function is started by pressing
PRINT. The time interval between two consecutive prints can be set to 0 or from 2 seconds to 1
hour (please see the Print interval menu item in the par. “4.3.2 Print Interval”). If the print interval
is equal to 0, by pressing PRINT a single data is sent to the connected device. If the print interval is
higher than 0, the data transfer continues until the operator stops it by pressing PRINT again. The
“PN” message is displayed at the top of the display.
