  • Page 6: General Characteristics

    1. GENERAL CHARACTERISTICS The Thermohygrometer Model HD2301.0R is a portable instrument that measures an environment's temperature and relative humidity. It is fitted with a large LCD display for excellent visualization of the measured data. The Thermohygrometer Model HD2301.0R measures: • relative humidity and temperature using combined probes, fitted with a Pt100 temperature sensor or thermocouple;...

  • Page 7: Description Of The Functions

    2. DESCRIPTION OF THE FUNCTIONS The keyboard of the Thermohygrometer HD2301.0R 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.
  • Page 8 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. CLR/ESC key The "CLR" key has two functions: • CLEAR (CLR): allows to reset the maximum (MAX), minimum (MIN) and average (AVG) value of the captured measurements;...
  • Page 9 UNIT/MENU key The "UNIT" key is used for the following functions: • UNIT: by pressing this key the unit of measurement of the main input quantity is selected: the unit of measurement will appear in the upper part of the display; the measured value will be displayed in the central line.

    • direct 4 wire "Pt100" probes complete with TP47 module • 2 wire "Pt1000" probes complete with TP47 module NOTE: The probes fitted with SICRAM module, and Delta Ohm "Pt1000" probes, are automatically detected by the instrument upon turning on. The type of probe is configured by the instrument and cannot be modified by the user.

  • Page 11: Probes And Measurements

    The Delta Ohm Pt1000 probes are automatically detected while the direct 4 wire Pt100 temperature probe is not automatically detected by the instrument and must be set up in the Probe type menu item (please see the menu description on chapter 3).

  • Page 12: Calibration Of The Combined Humidity/Temperature Probe

    4.1.2 Calibration of the combined humidity/temperature probe Caution! 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.

Remove the probe from the 75%RH container and close it immediately using its cap. Calibrating the points at 33%RH and 11%RH Repeat the points from 3) to 9) using the saturated salts at 33%RH and 11%RH When completed, unscrew the ring with the cap, and screw the protection grid back on the sensors.

    4.2.2 Connecting the TP47 connector for the 4 wire Pt100 and 2 wire Pt1000 probes All probes produced by Delta Ohm are provided with a connector. The Thermohygrometer Model HD2301.0R also work with direct 4 wire Pt100, and 2 wire Pt1000 probes manufactured by other producers: for the instrument connection is prescribed the TP47 connector to which the probe's wires should be welded.

    6. INSTRUMENT SIGNALS AND FAULTS The following table lists all error indications and information displayed by the instrument and supplied to the user in different operating situations: Display indication Explanation This appears in the display central line when a temperature only probe is connected. In the lower line - - - the temperature is shown correctly.

    7. 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.
