Page 3: General Characteristics
GENERAL CHARACTERISTICS The Thermohygrometer Model HD2301.0 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 HD2301.0 measures: • relative humidity and temperature using combined probes, fitted with a Pt100 temperature sensor or thermocouple;... - Page 4 Thermohygrometer HD2301.0 - 4 - HD2301 V1.7...

Page 6: Description Of The Functions
DESCRIPTION OF THE FUNCTIONS The keyboard of the thermohygrometer HD2301.0 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 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 : once the MENU has been opened with the DATA+UNIT keys, the key will • allow to increase the value of the selected parameter. 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 The UNIT key is used for the following functions: UNIT: by pressing this key the unit of measurement of the main input quantity is...

THE PROGRAMMING MENU To access to the menu press simultaneously the following keys: The items to be set are listed in this order: 1. 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. -
Page 10: 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 previous chapter). -
Page 11: Calibration Of The Combined Humidity / Temperature Probe
ALIBRATION 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. - Page 12 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% When completed, unscrew the ring with the cap, and screw the protection grid back on the sensors. The calibration is now complete. Important notes: 1) Do not let hands touch the RH sensor.

A tolerance according to norm IEC751 - BS1904 - DIN43760. The probes with SICRAM module and the Delta Ohm Pt1000 probes are detected by the instrument; the model configuration is required for the other probes (please see the description of the Probe Type menu item on page 9). - Page 14 5. 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: Not Used Ni1000...

8. Insert the gasket in the module; 9. Screw the fairlead and the ring. 10.At the other end of the module, enter the ring with the O-Ring as indicated in the picture. 11.Make sure the cable is not twisted while you are screwing the fairlead. Now the probe is ready. -
Page 16: Warnings
WARNINGS 1. Probes are not insulated from their 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. -

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