1. GENERAL CHARACTERISTICS

The HD32.7 RTD datalogger is an instrument that can capture, log and then send to a PC or serial

printer the data coming from 8 temperature probes with Pt100 or Pt1000 sensor connected to the

inputs.

The probes can be Pt100 with SICRAM module, direct 4-wire Pt100 or direct 2-wire Pt1000. All

the connected probes must be of the same type.

The Pt100 SICRAM probes are fitted with an electronic circuit that communicates with the

instrument. The sensor calibration information, the probe’s type and the serial number are

memorized inside. Thanks to the SICRAM module, the probes’ interchangeability on the instrument

is guaranteed. While the probes with SICRAM module are calibrated in the factory and can be

recalibrated, the 4-wire Pt100 and 2-wire Pt1000 probe uncertainty depends on the sensor quality.

All probes are detected during turn on: After connecting or disconnecting a probe, turn the

instrument off and on.

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 connected probes.

Other user selectable/settable parameters are:

•The type of probes connected to the instrument inputs.

•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 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 96,000 recordings from 8 inputs each.

The memory space can be handled in two modes:

•When the available memory is full, the collected data are overwritten starting from the

oldest ones (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.

The turning on starts a self test including the detection of the probes connected to the inputs. As the

SICRAM probes’ identification and calibration data are captured upon turning the

instrument on, it is necessary to connect the probes when the instrument is off. If a SICRAM

probe is connected and the instrument is on, the “New” indication appears on the display and

an intermittent beep is issued: It is necessary to turn the instrument off and on.

Once turned off, wait few seconds before turning it on to allow completion of the shut down

routine.

The type of probe connected to the inputs (Pt100 with SICRAM, direct 4-wire Pt100 or direct 2-

wire Pt1000) is selected from the menu. (Please see the “Input” paragraph on page 22.)

2.1 The Display

The HD32.7 standard display is divided in two areas:

The first area displays the battery’s charge status and the current time (above); then, the

temperatures measured by the probes connected to the inputs (below) arranged on two columns.

The unused inputs are indicated by dashes.

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.

In the example, the function keys are associated to the temperature measurement units:

°C: Celsius degrees

°F: Fahrenheit degrees

°K: Kelvin degrees

2.2 The Keyboard

The keys on the instrument perform the following functions:

ON/OFF key

It turns the instrument on and off.

When turning on the instrument using this key, the first screen will be displayed with the logo and

model. After few seconds the temperatures measured by the probes connected will be displayed.

- 8 -

NOTE: The non-connected inputs will be indicated by dashes. If a probe is disconnected when the

instrument is on, the “LOST” message will be displayed in case of a SICRAM probe, or dashes in

the other cases: Reconnect the probe to read the measured temperature. Do not connect the probes

when the instrument is on: In order to correctly detect them, you need to turn the instrument off and

then back on again.

TIME key

It allows the display of year/month/day and hour/minutes/seconds, in the first line for about 8

seconds. Normally the display shows, on the left, the icon for the battery’s charge status, on

the right, the hour/minutes/seconds. The battery symbol becomes [~] when the external power

supply is connected.

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 last 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).

SETUP key

It allows to enter and exit the instrument’s functioning parameter setting menu.

- 9 -

ENTER key

In the menu, it confirms the entered data.

ESC key

It allows to exit from the menu or, in case of a submenu, to move up one level.

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. During measurement, the ◄► arrows change the display

contrast.

3. OPERATION

Before turning on the instrument, connect the probes to the 8-pole male DIN45326 inputs, located

in the lower part of the instrument (see figure on page 2).

All probes must be of the same type: The selection of the type of probe should be performed in the

Input menu item (please see page 22).

NOTE: Connect the probes when the instrument is off. If a new probe is connected when the

instrument is on, the “New” indication appears on the display for a SICRAM probe, or dashes

for another probe. Turn the instrument off and then back on again to enable the new probe.

If a SICRAM probe is disconnected when the instrument is on, you will get an acoustic signal (a

beep) and an indication on the display near the physical quantity being disconnected. The “LOST”

message will be displayed.

The Pt100 probe with SICRAM module is fitted with an electronic circuit that communicates with

the instrument. The sensor calibration information are memorized inside. This guarantees its

interchangeability.

Connect the probes. Turn on the instrument: After few seconds, the display will appear as follows:

The battery charge symbol and current time are in the upper part (for further details, see the chapter

8).

Then the temperatures detected by each input are displayed. Use the F1, F2 and F3 keys to select

the unit of measurement (°C, °F or °K).

3.1 The unit of measurement “Unit”

By using the “Functions” menu, enabled by the SHIFT FNC key, select the unit of measurement

for the temperature in °C (Celsius), °F (Fahrenheit) or °K (Kelvin) degrees, as follows:

1. Use SHIFT FNC to open the drop-down menu;

2. Use the arrows ▲▼ to select unit;

3. Press ENTER to confirm: The selected quantity is displayed in the central line of the display;

4. The three different temperature units of measurement are shown in the bottom line of the

display using F1, F2 or F3: The selected unit is displayed near the measured value;

5. Press ESC to exit the drop-down menu without making any change.

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;
