Page 3: Introduction
INTRODUCTION The HD2101.1 and HD2101.2 are portable instruments with a large LCD display. They measure relative humidity and temperature using a Pt100 sensor or thermocouple humidity/temperature combined probe. Temperature only is measured by immersion, penetration or air contact probes. The sensor can be a Pt100, Pt1000 or Ni1000. When the combined humidity/temperature probe is connected, the instrument calculates and displays the absolute humidity, the dew point, the partial vapour pressure, and the comfort indices. - Page 4 Hygro-Thermometer HD2101.1 - 4 - HD2101 V2.3...

Page 8: Keyboard And Menu Description
KEYBOARD AND MENU DESCRIPTION Foreword The instrument keyboard is composed of single-function keys, like the MENU 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". - Page 9 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. FUNC/ENTER key During normal measurement this 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.
- Page 10 %RH probe calibration Simultaneous pressure on the UNIT and FUNC keys starts the calibration procedure of the probe connected to the instrument. Please see the paragraph dedicated to calibration on page 14. °C/°F - ESC key Changes the unit of measurement for the temperature from degrees Celsius to Fahrenheit for both the main and secondary variable.

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.
- Page 13 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.

Page 14: The Probes
THE PROBES The instrument works by using combined humidity/temperature probes (temperature with a Pt100 sensor or thermocouple) and with temperature only probes with 4 wire Pt100, or 2 wire Pt1000 or Ni1000. The combined humidity/temperature probes are fitted with SICRAM module that acts as an interface between the sensor on the probe and the instrument. - Page 15 The probes are calibrated in our laboratory at 23°C at the points of 75%RH, 33%RH and 11.4%RH. On request, the probes can be checked at different isotherms. The calibration of the temperature sensor by the user is not required: the sensor is calibrated in the factory and the Callendar Van Dusen parameters are recorded in the SICRAM module.

this case the chamber cannot reach its saturation anymore. For the saturated solutions at 75%RH, check that the salt is not dry (crystallized) for in order to reach the saturation, it needs to be wet 5) Storage of the saturated solutions: the saturated solutions must be stored in a dark environment at a constant temperature of about 20°C with the container well closed inside a dry room Relative humidity of saturated salts at different temperatures Temp... - Page 17 According to the value supplied by the DI index (Discomfort Index), the climatic conditions range from comfortable to somewhat annoying, and then intolerable: Comfortable Not very annoying Annoying Very annoying Intolerable There are four possible causes of local discomfort: • high vertical difference of temperature •...

Page 18: Direct Input Into Pt100, Pt1000 And Ni1000 Temperature Probes
Pt100, Pt1000 and Ni1000 T IRECT INPUT INTO EMPERATURE PROBES The instrument accepts the input of Platinum temperature probes with resistances of 100Ω and 1000Ω, as well as Nickel temperature probes with a 1000Ω resistance. The Pt100 are connected to 4 wires, the Pt1000 and Ni1000 to 2 wires, with the excitation current chosen minimizing the sensor self-heating effects. - Page 19 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...

Page 24: 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. -
