  • Page 3: General Characteristics

    GENERAL CHARACTERISTICS The HD2304.0 Manometer - Thermometer is a portable instrument that allows measurement of absolute, relative and differential pressure, and temperature. • The PP471 electronic module is used to measure the pressure. The module works as an interface between the instrument and the TP704 and TP705 series Delta Ohm probes.

  • Page 6: Description Of The Functions

    DESCRIPTION OF THE FUNCTIONS The keyboard of the HD2304.0 Manometer – Thermometer is composed of double- function keys. The function on the key is the "main function", while the one above the key is the "secondary function". When the instrument is in standard measurement mode, the main function is active. Once the Settings Menu has been opened, by pressing simultaneously the DATA+UNIT keys, the secondary function is enabled.
  • Page 7 Disabling of the 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. Press simultaneously the ON/OFF key and the HOLD key to disable this function. In this case, remember to turn the instrument off using the ON/OFF key: disabling of the automatic turning off is shown by the blinking battery symbol.
  • Page 8 Pressed together with the ON/OFF key, during turn on, the AutoPowerOff function is disabled (see the description of the ON/OFF key). UNIT/MENU key The UNIT key is used for the following functions: UNIT: by pressing this key the unit of measurement of the input probe is •...
  • Page 9 REL/  The REL key is used for the following functions: REL: it displays the difference between the current value and that measured on • pressing the key. The "REL" message is displayed on the left. To return to the normal measurement, press the key again.

    THE PROGRAMMING MENU To access to the menu press simultaneously the following keys: Menu: Probe type: the "PRBE_TYPE" message is displayed 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: TP704 and TP705 pressure probes combined with the PP471 module: the type •...

  • Page 11: Probes And Measurements

    PROBES AND MEASUREMENTS The instrument measures absolute, relative and differential pressure using the PP471 SICRAM module and the TP704 and TP705 series probes. It also measures the temperature with a Pt100 sensor with SICRAM module or with direct 4 wire Pt100 probes.

  • Page 12: Pt100 Temperature Probes

    Pt100 TEMPERATURE PROBES The instrument accepts the input of platinum temperature probes with resistances of 100Ω (Pt100). The Pt100 sensors are connected to 4 wires; the excitation current was chosen in order to minimize the sensor self-heating effects. All probes with module are calibrated in the factory; no calibration is usually required by the user.

  • Page 16: Warnings

    WARNINGS 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. Some pressure probe models are suitable for measurement of non-corrosive gases or air and dry and not liquid only: check the membrane compatibility with the plant fluid.

    INSTRUMENT STORAGE Instrument storage conditions: Temperature: -25…+65°C. • Humidity: less than 90%RH without condensation. • Do not store the instrument in places where: • • humidity is high; • the instrument may be exposed to direct sunlight; • the instrument may be exposed to a source of high temperature; •...

  • Page 18: Low Battery Warning And Battery Replacement

    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. If you continue to use it, the instrument can no longer ensure correct measurement.
