They measure illumination, luminance, PAR and irradiance (across VIS-NIR, UVA, UVB and UVC spectral regions or in the measurement of effective irradiance according to the UV action curve). The probes are fitted with the SICRAM automatic detection module: in addition to detection, the unit of measurement selection is also automatic. The factory calibration settings are ...

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”. When the instrument is in standard measurement mode, the main function is active. In the menu or in conjunction with the FUNC key, the se ...

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. The acquisition frequency is once a second. The MAX, MIN and AVG measurements remain in the memory until the instrument is on, even after exiting the calculation function. To reset the previous values ...

data recorded using the LOG function (HD2102.2) and sent to the printer or PC through the serial port using the SERIAL function (HD2102.1 and HD2102.2), keep the chosen unit of measurement and display it. While setting the limits for Q(t) calculation, select the coefficient 3, 6 and 9 that multiplies the displayed value respectively by 103, 106, 109. + Integra ...

TIME LIMT HOUR: indicates the number of hours for the integration time limit, after which the integral calculation is stopped. 3. TIME LIMT MIN: indicates the number of minutes for the integration time limit, after which the integral calculation is stopped. 4. TIME LIMT SEC: indicates ...

Values from 1200 to 38400 baud. Use the arrows to modify this parameter and confirm using ENTER. The communication between instrument and PC (or serial port printer) only works if the instrument and PC baud rates are the same. If the USB connection is used this parameter value is automatically set (please see the details on page 21). + Reset integral Q(t) Simultaneous pr ...

SERIAL/EraseLOG key - only HD2102.2 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. The printing operation is accompanied by the display of t ...

probes that measure illuminance (LP471 PHOT), irradiance (LP471 RAD, LP471 UVA, LP471 UVB and LP471 UVC), PAR (LP471 PAR) and luminance (LP471 LUM 2). All the probes, save the LUM 2, are provided with a diffuser for cosine correction. Upon turning on the instrument automatically detects the probe connected to the input: it is sufficient to connect it. ...

press Start/Stop Q(t). To cancel the previous integration values and reset it, simultaneously press FUNC/ENTER and MENU/CLR-Q(t): if an integration is started without pressing the CLR- Q(t) key, the calculation will continue from the previous values. The integral calculation can be suspended at any moment pressing Start/Stop Q(t): in this status, to resume the integra ...

1. Do not bend the probe connectors or force them upward or downward. 2. Do not bend or force the contacts when inserting the probe connector into the instrument. 3. The sensors and filters should not exceed the temperature limits established with consequent irreparable degradation of their characteristics. 4. Do not drop the probes: as this could cause irreparable damage. 5. Avoid taking measurements in presence of high ...

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. The memory data are maintained. If the battery charge level ...

After replacing the batteries, the instrument may not restart correctly; in this case, repeat the operation. After disconnecting the batteries, wait a few minutes in order to allow circuit condensers to discharge completely; then reinsert the batteries. WARNING ABOUT BATTERY USE • Batteries should be removed when the instrument is not used for an extended time. • Flat batteries must be replaced i ...

The HD2102.1 and HD2102.2 instruments are fitted with an electrically isolated RS-232C serial interface; the HD2102.2 also has an USB 2.0 interface. The HD2102.1 is supplied with a serial connection cable with a Sub D 9-pole female connector on one end, and an 8-pole MiniDin on the other end. The HD2102.2 also has a cable with USB 2.0 connector on one end, and 8-pole MiniDin on the other end (code HD2101/USB). The USB connection r ...
