INTRODUCTION
The HD2107.1 and HD2107.2 are portable instruments with a large LCD display. They measure the
temperature using immersion, penetration or air contact probes. The sensor can be a Pt100 3 or 4
wires, Pt1000 or Ni1000 2 wires.
The probes are fitted with automatic detection module, with the factory calibration settings already
being memorized inside.
The HD2107.2 instrument is a datalogger. It memorizes up to 80,000 samples which can be transferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. The logging interval, printing, and baud rate can be configured using the menu.
The HD2107.1 and HD2107.2 models are fitted with an RS232C serial port and can transfer the acquired measurements in real time to a PC or to a portable printer.
The Max, Min and Avg function calculate the maximum, minimum or average values.
Other functions include: the relative measurement REL, the HOLD function, and the automatic
turning off that can also be disabled.
The instruments have IP66 protection degree.
This manual describes the HD2107.1 and HD2107.2 models: if not otherwise specified, the description is intended to be applicable to both models.

KEYBOARD AND MENU DESCRIPTION
Foreword
The instrument keyboard is composed of single-function keys, like the MENU key, and doublefunction keys such as the ON-OFF/Auto-OFF key.
In the double-keys, the function in the upper part is the “main function”, while the one in the bottom
part is the “secondary function”. When the instrument is in standard measurement mode, the main
function is active. In the menu or in conjunction with the FUNC key, the secondary function is enabled.
The pressing of a key is accompanied by a short confirmation beep: a longer beep sounds if the
wrong key is pressed.
Each key specific function is described in detail below.
ON-OFF/Auto-OFF key
The instrument is turned on and off using the ON/OFF key. The turning on enables all display segments for a few seconds, and then the type of calibration enabled (CAL FACT = factory calibration;
CAL USER = user calibration). Then an auto-test follows, including detection of the probe connected to the input, and setting the instrument ready for normal measurement.

During turning on, should no probes be connected, the message "NO_PRBE_
SER_NUM" is displayed in the line for symbols for a few seconds, and in the main line
the ERR message appears.
When the probe is inserted into a functioning instrument, the "NEW_PROB_DET" (New
probe detected) message appears: as the probe's data are captured upon turning the instrument on, it is necessary to turn the instrument off and on again.
Replace the probes when the instrument is off.
+
Automatic turning off
The instrument has an AutoPowerOff function that automatically turns the instrument off after about
8 minutes if no key is pressed during the intervening time. The AutoPowerOff function can be dis-
abled by holding the HOLD key pressed down during the turning on phase: the battery symbol will
blink to remind the user that the instrument can only be turned off by pressing the <ON/OFF> key.
The automatic turning off function is disabled when external power is used. On the other
hand, it cannot be disabled when the batteries are discharged.
HD2107 - 9 - V2.3
FUNC key
It enables the display and logging of the maximum (MAX), minimum (MIN) and average (AVG)
value of the measurements captured by the probe connected to the instrument, updating them with
the acquisition of new samples. The acquisition frequency is once a second.
The MAX, MIN and AVG measurements remain in the memory until the instrument is on, even after exiting the calculation function. To reset the previous values and restart with a new measurement
session, press FUNC until the message “FUNC CLR” appears, then use the arrows to select YES
and confirm using ENTER.
Attention: the data captured using the Record function cannot be transferred to the PC.
HOLD/ key
It increases the current parameter when used in the menu; when used in measurement mode, it
freezes the measurement in progress, and upon application of pressure on the key, the message
HOLD appears in the upper side of the display. To return to the current measurement, press the
key again.
Upon turning on the instrument, the AutoPowerOff function can be disabled by holding the MENU
key down (please see the ON-OFF key description).
UNIT/UserCAL key
During measurement allows selection of the unit of measurement for the input temperature (shown
in the central line of the display). By repeatedly pressing the function key, the different units of
measurement are displayed in sequence:
1. °C Ce lsius degr ees
2. °F Fahrenheit degrees
3. °K Kelvin degrees
This setting changes the information displayed and the immediate print of data (SERIAL key). The
data recorded using the LOG function (HD2107.2) and sent to the printer or PC through the
serial port using the SERIAL function (HD2107.1 and HD2107.2), keep the chosen unit of
measurement and display it.
+
Calibration of the probe and selection of the type of calibration
Simultaneous pressure on the UNIT/UserCal and FUNC keys starts the calibration procedure of the
temperature probe connected to the instrument. Please see the paragraph dedicated to calibration on
page 14.
To select the type of calibration (USER=user or FACT= factory) press the UNIT/UserCal and
FUNC keys together, then use the arrows to select the desired item, and confirm using ENTER.
HD2107 - 10 - V2.3
ENTER key
In the menu, the ENTER key confirms the displayed parameter and then goes to the next one.
REL/ key
In measurement mode, it displays the difference between the current value and that measured on
pressing the key. The REL message appears on the display; press the key again to return to the
current measurement.
When used in the menu, it decreases the current variable value.
MENU Key
The first menu item is accessed by initially pressing on the MENU key; press ENTER to go to the
following items. To modify the item displayed, use the arrow keys ( and ). By pressing the
ENTER key, the current value is confirmed and the display moves on to the next parameter. By
pressing the FUNC key, the setting is cancelled.
To exit the menu, press the MENU key at any time.
The menu items are listed in this order:
1) Management of memorized data (only HD2107.2): the message “>>>_LOG_DUMP_or-
_ERAS” (Transfer data or erase) is scrolled in the comment line.
The center figure reports the number of free memory pages (FREE). All memory data are
permanently erased by pressing SERIAL/EraseLOG. By pressing LOG/DumpLOG, the data
transfer of the logged data on the serial port is started: the “BAUD-RATE” must have previously been set to the maximum value (please see the menu items described below and the
paragraph "STORING AND TRANSFERRING DATA TO A PERSONAL COMPUTER"
on page 25).
2) RTD probe type: the message “RTD_PRBE_TYPE" is scrolled in the comment line. The
main line in the center of the display shows the type of probe connected to the instrument.
The following probes can be connected to the input:
• temperature probes Pt100 complete with SICRAM module
• direct 4 wire Pt100 probes through module TP47
• direct 3 wire Pt100 probes through module TP47
• 2 wire Pt1000 probes through module TP47
• 2 wire Ni1000 probes through module TP47
Upon turning on the instrument automatically detects the probes fitted with SICRAM module: the Probe Type menu item is configured to AUTO and cannot be modified by the user.
When turned on, the temperature probes direct 4 wire Pt100, direct 3 wire Pt100, the Pt1000
and the Ni1000 display the message "NO_PRBE_SER_NUM" (no probe serial number).
HD2107 - 11 - V2.3
In this case the probe type must be entered manually. Select Probe type using the
MENU key and then select the type of probe used with the arrow keys; confirm using
ENTER.
3) Print and log interval: sets the interval in seconds between two loggings or data transfers
to the serial port. The interval can be set at 0, 1s, 5s, 10s, 15s, 30s, 60s (1min), 120s (2min),
300s (5min), 600s (10min), 900s (15min), 1200s (20min), 1800s (30min) and 3600s (1hour).
If the value 0 is set, SERIAL works on command: the sending of data to the serial port
is performed each time the key is pressed. Recording (LOG) is performed with one sec-
ond intervals even if the interval is set to 0. With an interval from 1 to 3600s, continuous
data transfer is started when the SERIAL key is pressed. To end the recording (LOG) and
continuous data transfer operations (SERIAL with an interval greater than 0), press the
same key again.
4) Sleep_Mode_LOG (Automatic turning off during recording) (only HD2107.2): this
function controls the instrument's automatic turning off during logging, occurring between
the capture of a sample and the next one. When the interval is lower than 60 seconds, the instrument will always remain on. With intervals greater than or equal to 60 seconds, it is possible to turn off the instrument between loggings: it will turn on at the moment of sampling
and will turn off immediately afterwards, thus increasing the battery life. Using the arrows
select YES and confirm using ENTER in order to enable the automatic turning off, select
NO and confirm to disable it and keep the instrument on continuously.
Note: even if Sleep_Mode_LOG=YES is selected, the instrument does not turn off for less
than one minute intervals.
5) YEAR: to set the current year. Use the arrows to modify this parameter and confirm using
ENTER.
6) MNTH (month): to set the current month. Use the arrows to modify this parameter and con-
firm using ENTER.
7) DAY: to set the current day. Use the arrows to modify this parameter and confirm using
ENTER.
8) HOUR: to set the current hour. Use the arrows to modify this parameter and confirm using
ENTER.
9) MIN (minutes): to set the current minutes. In order to correctly synchronize the minute, it is
possible to reset the seconds by pressing the UNIT key. Use the arrows to set the current
minute plus one, and as soon as that minute is reached press UNIT: this synchronizes the
time to the second. Press ENTER to go onto the next item.
10) BAUD_RATE: indicates the frequency used for the serial communication with the PC.
Values from 1200 to 38400 baud. Use the arrows to modify this parameter and confirm using ENTER. The communication between instrument and PC (or serial port printer)
only works if the instrument and PC baud rates are the same. If the USB connection is
used this parameter value is automatically set (please see the details on page 25).
HD2107 - 12 - V2.3
LOG/DumpLOG key - only HD2107.2
In measurement mode, this function starts and stops the logging of a data block to be saved in the
instrument's internal memory. The data logging frequency is set in the "Print and log interval"
menu parameter. The data logged between a start and subsequent stop represent a block.
When the logging function is on, the LOG indication is displayed, the battery symbol blinks and a
beep is issued each time a logging occurs; the battery symbol does not appear when using an
external power supply.
To end the logging, press LOG.
The HD2107.2 can turn off during logging between one capture and the next: the function is controlled by the Sleep_Mode_LOG parameter. When the logging interval is less than one minute, the
logging instrument remains on; with an interval of at least one minute, it turns off between one capture and the next if the parameter Sleep_Mode_LOG=YES.
>>>
Dump LOG - only HD2107.2
When the LOG key is pressed after the MENU key, the transfer of the logged data on the serial port
is started.
Please see the paragraph dedicated to data transfer on page 25.
SERIAL key - only HD2107.1
SERIAL/EraseLOG key - only HD2107.2
In measurement mode, this function starts and stops the data transfer to the RS232C serial output.
According to the settings entered in the Print and log interval menu item, a single sample can be
printed if Print and log interval=0 or a continuous indefinite printing of the measured data can be
set up if Print and log interval=1…3600.
The printing operation is accompanied by the display of the RS232 symbol and the blinking of the
battery symbol; when using an external power supply the battery symbol does not appear.
Press SERIAL to end the continuous printing.
Before starting the printing with SERIAL, set the baud rate. To do so, select the Baud Rate menu
item and select the maximum value equal to 38400 baud by using the arrows. Confirm by pressing
ENTER.
The DeltaLog9 software for PC will automatically set the baud rate value during connection. If you
are using a different program than DeltaLog9, be sure the baud rate is the same for both the
instrument and the PC: the communication will only work in this way.
HD2107 - 13 - V2.3

Erase memory - only HD2107.2
When pressed after the MENU key, the SERIAL key permanently erases all the data contained in
the instrument's memory.
HD2107 - 14 - V2.3
THE PROBES
The instrument works with temperature probes fitted with the SICRAM module (with a Platinum
Pt100 sensor with 100Ω resistance) and with direct 4 wire Pt100, direct 3 wire Pt100, 2 wire Pt1000
and Ni1000 sensors. The excitation current was chosen in order to minimize the sensor self-heating
effects. The SICRAM module acts as an interface between the sensor on the probe and the instrument: there is a microprocessor circuit with a permanent memory inside the module that enables the
instrument to recognize the type of probe connected and to read its functioning information.
The probes with SICRAM module are automatically detected by the instrument, while the direct
probes must be set up in the Probe type menu item (please see the description of the menu on page
10).
The probe is detected during turn on, and this cannot be performed when the instrument is
already on, therefore if a probe is connected and the instrument is on, it is necessary to turn it
off and on.
TEMPERATURE MEASUREMENT
In all versions the temperature sensor is housed at the end of the probe.
The response time for the measurement of the temperature in air is greatly reduced if the air is mov-
ing. If the air is still, stir the probe. The response times are longer than those for liquid measurements.
The temperature measurement by immersion is carried out by inserting the probe in the liquid for at
least 60mm; the sensor is housed in the end part of the probe.
In the temperature measurement by penetration the probe tip must be inserted to a depth of at least
60mm, the sensor is housed in the end part of the probe. 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. A contact measurement is
hard to perform due to various factors: the operator must be experienced in handling the probe and
consider all the factors influencing it.
So as to obtain the correct measurement, the insertion of a drop of oil or heat-conductive
paste is useful (do not use water or solvents). This method also improves the response time.
The °C, °F or °K unit of measurement can be chosen for display, printing, and logging using the
UNIT/UserCal key.
Calibration of the temperature probe on line with the instrument
To calibrate the probes correctly, a knowledge of and abiding by the physical phenomena on which
the measurement is based is fundamental: this is the reason why it is recommended to abide by what
is reported below carefully, and only to perform new calibrations if technically proficient and using
the suitable equipment.
The probes fitted with SICRAM module are calibrated in the factory and the calibration parameters are recorded in the module. All probes with direct input are checked for conformity
with class A tolerance according to norm IEC751 - BS1904 - DIN43760.
HD2107 - 15 - V2.3
The instrument is provided with the FACT (factory) calibration. The user is also able to perform a
USER calibration of instrument+probe. The calibration information is saved in the instrument
memory and not in the probe. The same correction is applied to any probe connected to the input: it
is therefore implied that the USER calibration should only be used with a precise probe: the one
used during calibration and no other probe.
To pass from the user to the factory calibration and back, press the UNIT/UserCal and
FUNC/ENTER keys together, then use the arrows to select the type of calibration, and confirm using ENTER.
Calibration sequence:
The calibration can be carried out on one or two points that should differ by at least 10°C and be
included in the probe functioning range.
Insert the probe into a thermostatic bath, the temperature of which is precisely known from a reading taken on a sample reference thermometer. Wait for the measurement to stabilize.
Press simultaneously the UNIT/UserCal and FUNC keys, using the arrows select the USER calibration, and confirm with UNIT/UserCal.
Use the arrows to select 1 (first calibration point) and confirm with ENTER. The "UP DOWN 1st
MEAS" (correct the first point using the arrows /) message is scrolled in the comment line. The
instrument display shows the measured temperature: use the arrows to correct the indicated value
until it coincides with the value measured by the sample reference thermometer.
Confirm by pressing ENTER.
To exit the procedure without performing the second point, select 0 and press ENTER.
To perform the second point, select the point 2 with the arrows and press ENTER.
The "UP DOWN 2nd MEAS" (correct the second point using the arrows /) message is scrolled
in the comment line.
Move the probe to the second thermostatic bath and wait for the measurement to stabilize. The instrument display shows the measured temperature: use the arrows to correct the indicated value until it coincides with the value measured by the sample reference thermometer.
Confirm by pressing ENTER.
The procedure is now complete.
Instructions to connect the TP47 connector for 4 wire Pt100, Pt1000 and Ni1000 probes
All Delta Ohm probes are provided with a connector. The HD2107.1 and HD2107.2 instruments
also work with 4 and 3 wire direct Pt100, Pt1000 and Ni1000 probes manufactured by other producers: for the instrument connection is prescribed the TP47 connector to which the probe's wires
should be welded.
The instructions to connect the Platinum or Nickel probe to the module are provided below.
The module is supplied complete with fairlead and gasket for 5mm maximum diameter cables.
HD2107 - 16 - V2.3
Do the following to open the module and connect a probe:
Unscrew the fairlead and extract the gasket, remove the label using a cutter, unscrew the ring on the
opposite side as illustrated in the figure:
Open the two module shells: the printed circuit to which the probe must be connected is housed inside. On the left there are the 1…4 points on which the sensor wires must be welded. The JP1…JP4
jumpers are in the center of the board. These must be closed with a tin bead for some type of sensors:

module, enter the ring with the O-Ring as indicated in the picture.
Make sure the cable is not twisted while you are screwing the fairlead. Now the probe is ready.
Direct connection of 4 wire Pt100 sensors
4 wire Pt100 sensors can be soldered directly
to the pins of the free female connector without making use of the TP47 board. The 4
wires of the Pt100 sensors have to be soldered
as indicated in the figure on the left.
In order to use this type of probe it is necessary to set up the menu item “Probe Type” as
described at page 10.
The P100 probe is recognized upon turning on
the instrument: connect the probe when the instrument is switched off and then turn it on.

WARNINGS AND OPERATING INSTRUCTIONS
1. Do not expose the probes to gases or liquids that could corrode the material of the sensor or the
probe itself. Clean the probe carefully after each measurement.
2. Do not bend the probe connectors or force them upward or downward.
3. Do not bend or force the contacts when inserting the probe connector into the instrument.
4. Do not bend, deform or drop the probes, as this could cause irreparable damage.
5. Always select the most suitable probe for your application.
6. Do not use probes in presence of corrosive gases or liquids. The sensor container is made of
AISI 316 stainless steel, while the contact probe container is made from AISI 316 stainless steel
plus silver. Avoid contact between the probe surface and any sticky surface or substance that
could corrode or damage it.
7. Above 400°C and below –40°C, avoid violent blows or thermal shocks to Platinum temperature
probes as this could cause irreparable damage.
8. To obtain reliable temperature measurements, temperature variations that are too rapid must be
avoided.
9. Temperature probes for surface measurements (contact probes) must be held perpendicular
against the surface. Apply oil or heat-conductive paste between the surface and the probe in order to improve contact and reduce reading time. Whatever you do, do not use water or solvent
for this purpose. A contact measurement is always very hard to perform. It has high levels of
uncertainty and depends on the ability of the operator.
10. Temperature measurements on non-metal surfaces usually require a great deal of time due to the
low heat conductivity of non-metal materials.
11. The sensor is not insulated from its external casing; 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.
12. Avoid taking measurements in presence of high frequency sources, microwave ovens or large
magnetic fields; results may not be very reliable.
13. Clean the probe carefully after use.
14. The instrument is water resistant and IP66, but should not be immersed in water. Protect the
connectors from water by closing them well using their caps. The probe connectors must be fitted with sealing gaskets. Should the instrument fall into the water, check for any water infiltration. Gently handle the instrument in such a way as to prevent any water infiltration from the
connectors' side.

LOW BATTERY WARNING AND BATTERY REPLACEMENT
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. The memory
data are maintained.
If the battery charge level is insufficient, the following message appears when you turn the instrument on:
BATT TOO LOW
CHNG NOW
The instrument issues a long beep and turns off. In this case, replace the batteries in order to
turn the instrument back on.
In order to avoid data loss, the logging session is ended, if the HD2107.2 is logging and battery
voltage falls below the minimum operating level.
The battery symbol turns off when the external power supply is connected.
To replace the batteries, switch the instrument off and unscrew the battery cover counter clockwise.
After replacing the batteries (4 1.5V alkaline batteries - type AA) screw the cover on clockwise.
After replacing the batteries, the date, time, baud rate, type of probe, printing interval, logging parameters must be set again: in order to simplify the operation, on insertion of the new batteries
the instrument turns on automatically and requests these parameters in sequence. To go to the
next item press ENTER; to return to measurement mode, press MENU.
HD2107 - 22 - V2.3
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.
WARNING ABOUT BATTERY USE
• Batteries should be removed when the instrument is not used for an extended time.
• Flat batteries must be replaced immediately.
• Avoid batteries leaking.
• Always use good quality leakproof alkaline batteries. Sometimes on the market, it is possi-
ble to find new batteries with an insufficient charge capacity.

HD2107 - 23 - V2.3
SERIAL INTERFACE AND USB
The HD2107.1 and HD2107.2 instruments are fitted with an electrically isolated RS-232C serial interface; the HD2107.2 also has an USB 2.0 interface.
The following serial cables can be used:
• HD2110CSNM: serial connection cable with 8-pole MiniDin connector on one end and
9-pole Sub D connector on the other end;
• C.206: serial connection cable with 8-pole MiniDin connector on one end and USB type A
connector on the other end. With integrated RS232/USB converter;
• CP23: connection cable with Mini-USB type B connector on one end and USB type A con-
nector on the other end (only for HD2107.2).
The connection via the C.206 cable requires the previous installation of the cable USB drivers. Install the drivers before connecting the C.206 cable to the PC.
The connection via the CP23 cable does not require the installation of USB drivers: when connecting
the instrument to the PC, the Windows® operating system automatically recognizes the device as an
HID device (Human Interface Device) and uses the drivers already included in the operating system.

• N. bit 8
• Stop bit 1
• Protocol Xon/Xoff
It is possible to change the RS232C serial port baud rate by setting the "Baudrate" parameter in the
menu (please see page 11). The possible values are: 38400, 19200, 9600, 4800, 2400, 1200. The
other transmission parameters are fixed.
The USB 2.0 connection does not require the setting of parameters.
The instruments are provided with a complete set of commands and data queries to be sent via the PC.
The serial commands work with a standard serial communication program (e.g. Hyperterminal) only
through the RS232 serial port of the instrument, using the cable HD2110CSNM or the cable C.206.
All the commands transferred to the instrument must have the following structure:
XYcr where: XY is the command code and cr is the Carriage Return (ASCII 0D)

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). The instrument does not send the LF command (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.
HD2107 - 25 - V2.3
STORING AND TRANSFERRING DATA TO A PERSONAL COMPUTER
The HD2107.1 and HD2107.2 instruments can be connected to a personal computer via an RS232C
serial port or USB 2.0 port, and exchange data and information through the DeltaLog9 software
running in a Windows operating environment. Both models can send in real time input measured
values directly to a PC, through the PRINT function; the HD2107.2 can also store the values
measured by using the Logging function (LOG key) in its internal memory. If necessary, the data
stored in the memory can be transferred to a PC later.
THE LOGGING FUNCTION - ONLY FOR HD2107.2
The Logging function allows the recording up to 80,000 measurements registered by the probe connected to the input. The time interval between two consecutive measurements can be set from 1
second to 1 hour. The logging starts by pressing the LOG 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 page 10.
If the automatic turning off option between two recordings (menu >> Sleep_Mode_LOG) is enabled, upon pressing the LOG 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 DUMP LOG command: MENU
>> LOG. During data transfer the display shows the message DUMP; to stop the data transfer press
FUNC on the instrument or ESC on the PC.
CLEARING THE MEMORY - ONLY FOR HD2107.2
To clear the memory use the Erase Log function (MENU >> SERIAL).
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 logged data remain in memory apart from 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 work: ON/OFF, HOLD, FUNC
(Max-Min-Avg) and SERIAL.
• Pressing the HOLD, REL and FUNC keys has no effect on the logged data if these keys are
pressed after starting the recording, otherwise the following is valid.
• The recording started with the display in HOLD mode proceeds normally with the actual meas-
ured values (that is, not in “HOLD” mode). Only the display is frozen to the values present when
the HOLD key was pressed.
• The same is true for the Max-Min-Avg function.
• If the logging is started when the display is in REL mode, the relative values are logged.
• It is possible to activate both the logging (LOG) and direct transfer (PRINT) functions at the
same time.
HD2107 - 26 - V2.3
THE PRINT FUNCTION
The PRINT function sends the measurements taken in real time by the instrument inputs directly to
a PC or a printer. Print data units of measurements are the same as those used on the display. The
function is started by pressing SERIAL. The time interval between two consecutive prints can be set
from 1 second to 1 hour (please see the Print and log interval menu item on page 10). If the print
interval is equal to 0, by pressing SERIAL the 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
SERIAL again.
The PRINT function works with a standard serial communication program (e.g. Hyperterminal) only
through the RS232 serial port of the instrument, using the cable HD2110CSNM or the cable C.206.
Connect the HD40.1 printer using cable HD2110CSNM.
NOTES:
• The print out is formatted across 24 columns.
• Some keys are disabled during serial transmission. The following keys work: ON/OFF, HOLD,
FUNC (Max-Min-Avg) and LOG.
• Pressing the HOLD, REL and FUNC keys has no effect on the printed data if these keys are
pressed after starting the printing, otherwise the following is valid.
• The transfer started with the display in HOLD mode proceeds normally with the actual meas-
ured values (that is, not in “HOLD” mode). Only the display is frozen to the values present
when the HOLD key was pressed.
• The same is true for the Max-Min-Avg function.
• If the serial transfer is started when the display is in REL mode, the relative values are trans-
ferred.
• It is possible to activate both the logging (LOG) and direct transfer (PRINT) functions at the
same time.
