Page 3: Introduction
INTRODUCTION The HD2108.1 and HD2108.2 with one input and the HD2128.1 and HD2128.2 with two inputs are portable instruments with a large LCD display. They measure the temperature using immersion, penetration or air contact probes. The sensor may be a thermocouple of type K, J, T, N, R, S, B or The HD2108.2 and HD2128.2 instruments are dataloggers. - Page 4 HD2108.1 and HD2108.2 Thermocouple Thermometers with one input - 4 - HD2108/HD2128 V2.3...

Page 8: Keyboard And Menu Description
KEYBOARD AND MENU DESCRIPTION Foreword In some versions, the instrument keyboard is composed of single-function keys and double-function keys such as the ON-OFF/Auto-OFF. 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 MAX, MIN or AVG values for both inputs. In the models with one input, the HD2108.1 and HD2108.2, the display shows the current temperature in the main line and the maximum, minimum or average temperature in the secondary line.
- Page 10 Calibration of the probe and selection of the type of calibration Simultaneous pressure on the UNIT/UserCal and FUNC/Enter keys starts the calibration procedure of the temperature probe connected to the instrument. Please see the paragraph dedicated to calibration on page 14. To select the type of calibration (USER=user or FACT= factory) press the UNIT/UserCal and FUNC/Enter keys together, then use the arrows to select the desired item, and confirm using ENTER.
- Page 11 MENU Key The first menu item is accessed by initially pressing on the MENU key (A-B/Menu + FUNC/Enter in the HD2128.2 model); press ENTER to go to the following items. To modify the item displayed, use the arrow keys ( ).
- Page 12 8) MIN (minutes): to set the current minutes. In order to correctly synchronize the minute, it is possible to reset the seconds by pressing the UNIT key. Use the arrows to set the minutes, press the UNIT key to confirm: this synchronizes the time to the second. Press ENTER to go onto the next item.
- Page 13 SERIAL key - only HD2108.1 and HD2128.1 SERIAL/EraseLOG key - only HD2108.2 and HD2128.2 In measurement mode, this function starts and stops the data transfer to the RS232C serial output. According to the settings entered in the Print and log interval menu item, a single sample can be printed if Print and log interval=0 or a continuous indefinite printing of the measured data can be set up if Print and log interval=1…3600.

Page 14: The Probes
THE PROBES The instrument works with thermocouple probes of type K, J, T, N, R, S, B or E. The selection is done using the TC SEL key. The contacts of the thermocouple probe connector are polarized. They must be inserted on the standard mignon socket located on the instrument in the correct direction. - Page 15 the input: it is therefore implied that the USER calibration should only be used with a precise probe: the one used during calibration and no other probe. To pass from the user to the factory calibration and back again, press the UNIT/UserCal and FUNC/ENTER keys together, then use the arrows to select the type of calibration, and confirm using ENTER.
