INTRODUCTION
This manual describes the characteristics and operating modes of the HD2114.0, HD2134.0,
HD2164.0 micromanometers, the HD2114B.0 barometer, and the corresponding HD2114.2,
HD2134.2, HD2164.2 and HD2114B.2 models with datalogger function. They are portable
instruments with a large LCD display. They perform measurements of absolute, relative and
differential pressure, and temperature.
Pressure is measured using an internal differential module that compares the atmosphere with
bottom of a fixed scale. With the PP471 module acting as an interface, the instrument can use all
the TP704 and TP705 series Delta Ohm probes to perform the measurements. The HD2114B.0 and
HD2114B.2 internal module measures the barometric pressure.
The temperature is detected using immersion, penetration, contact or air probes, with SICRAM
module or direct 4-wire probes. The sensor can be a Pt100, Pt1000 or Ni1000. The temperature
probes are fitted with a SICRAM module, with the factory calibration settings already being
memorized inside. On being turned on the instrument automatically detects these settings.
The HD2114.2, HD2134.2, HD2164.2 and HD2114B.2 instruments are dataloggers. They
memorize up to 36,000 samples, which can be transferred from the instrument connected to a PC
via the RS232C serial port or USB 2.0 port. The storing interval, printing, and baud rate can be
configured using the menu.
The HD2114.2, HD2134.2, HD2164.2 and HD2114B.2 instruments can transfer via the RS232C
serial port the acquired measurements to a PC or to a portable printer in real time.
The Max, Min and Avg function calculates the maximum, minimum or average values. The Peak
function can be activated with external probes connected to the module PP471 and detects the
presence of pressure peaks. Other functions include the relative measurement REL, the HOLD
function, and the automatic turning off which can also be disabled.
The instruments have IP66 protection degree.
If not otherwise specified, this manual's descriptions are intended to be applicable to all
models.

KEYBOARD AND MENU DESCRIPTION
Foreword
The instrument keyboard is composed of single-function keys, like the UNIT key, and double-
function 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.
Note: the instrument is fitted with internal pressure sensor with a fixed full scale. If a SICRAM
PP471 module with TP704 or TP705 probe is connected, the internal sensor is disabled and
the display indicated pressure is that of the external probe.
All operations described below and relevant to pressure measurement, therefore apply to the
internal sensor unless the external PP471 module is connected. Please see the paragraph
dedicated to calibration on page 14.
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, starts an auto-test including the detection of the possible probe
connected to the input, and sets the instrument ready for normal measurement. During the auto-test,
the serial number of the connected probe is indicated in the comment line: e.g.
"PRB1_SER_1234_5678" means the probe with serial number 12345678 is connected to the input.
If no probe is connected to central input, the "NO_PRBE_ SER_NUM" message appears for
a few seconds in the line for symbols.
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
disabled by holding the HOLD key pressed down when turning the instrument on: 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 for the HD21...4.2 models is disabled when external power
is used. On the other hand, it cannot be disabled when the batteries are discharged.
FUNC/ENTER key
During normal measurement this enables the display of the maximum (MAX), minimum (MIN) and
average (AVG) value of the measurements captured by the instrument, updating them with the
acquisition of new samples. The acquisition frequency is once a second.
The MAX, MIN and AVG calculation begins upon turning on and is updated when the instrument
is in normal measurement mode. 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.
In the menu, the ENTER key confirms the current parameter and then goes to the next one. Pressed
together with the PEAK/MENU key, opens the menu (please see the PEAK/MENU key
description).
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 HOLD
key down (please see the ON-OFF key description).
UNIT key
In measurement mode, it allows selection of the unit of measurement of the pressure (shown in the
central line of the display). By repeatedly pressing the key, the different units of measurement are
displayed in sequence: Pa, hPa, kPa, mbar, bar, atm, mmHg, mmH2O, kgf/cm2, PSI, inchHg.
This setting changes the information displayed and, only for the HD21...4.2 models, also the
immediate print of data (SERIAL key). The data recorded using the LOG function (HD21...4.2)
keep the chosen unit of measurement displayed during logging.
The unit of measurement associated with the data sent to the printer or PC through the serial
port using the SERIAL function (HD21...4.2), must be selected before starting the print function.

°C/°F - ESC key
Changes the unit of measurement for the temperature between Centigrade or Fahrenheit.
When used in the menu, it clears or cancels the active function.
REL/key
In measurement mode, it displays the difference between the current value and that measured on
pressing the key for both measurements - main and secondary. 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 - only HD21...4.0
+
PEAK/MENU key - only HD21...4.2
The first menu item is accessed by initially pressing on the MENU key (FUNC/ENTER +
PEAK/MENU in the HD21...4.2 models); press ENTER to go to the following items. To modify the
item displayed, use the arrow keys (and ). The current value is confirmed by pressing the
ENTER key and the display moves on to the next parameter. If pressing ESC the setting is
cancelled.
To exit the menu, press the MENU or the PEAK/MENU key at any time.
The menu items are listed in this order:
1) Differential probes resetting: In the differential probes there can be a slight difference
between the two inputs, so the instrument does not indicate zero at comparable pressure
applied to the two inputs of a probe. This is the reason the reset command was designed for
the differential value: leave the inputs of each probe open so that they detect the same
pressure and enter the menu. The "PRES_REL_TO_ZERO ENTR_TO_MENU" message
appears: press REL to reset the difference or press ENTER to access other menu items. The
reset operation is applied to the internal pressure sensor if no differential probe
(TP705) is connected to the input.
2) Pressure probe full scale: the full scale and the enabled pressure probe type is presented.
3) Probe type: the message “>>>_PRBE_TYPE" is scrolled in the comment line. The main
line in the center of the display shows the type of temperature probe connected to the
instrument.
It is possible to connect:
Pt100 temperature probes complete with SICRAM module
4-wire Pt100 probes complete with TP47 module
2-wire Pt1000 probes complete with TP47 module
2-wire Ni1000 probes complete with TP47 module
