  • 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 This setting changes the information displayed and the immediate print of data (SERIAL key). The data recorded using the LOG function (HD2101.2) and sent to the printer or PC through the serial port using the SERIAL function (HD2101.1 and HD2101.2), keep the chosen unit of measurement and display it.
  • 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.
  • Page 11 2 wire Ni1000 probes complete with TP47 module Upon turning on the instrument automatically detects the probes fitted with SICRAM module, the Delta Ohm Pt1000 and Ni1000: the Probe Type menu item is configured by the instrument and cannot be modified by the user.
  • Page 12 When the LOG key is pressed after the MENU key, the transfer of the logged data on the serial port is started. Please see the paragraph dedicated to data transfer on page 28. SERIAL key - only HD2101.1 SERIAL/EraseLOG key - only HD2101.2 In measurement mode, this function starts and stops the data transfer to the RS232C serial output.
  • 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 Delta Ohm Pt1000 and Ni1000 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 description of the menu on page 11).
  • 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.

  • 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.
