HD2102 - 3 - V2.3
INTRODUCTION
The HD2102.1 and HD2102.2 are portable instruments with a large LCD display. 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 already
memorized inside the instruments.
In addition to instantaneous measurement the instruments calculate the acquired measurements time
integral Q(t). Some thresholds can be associated with the integrated measurement and with the
integration time, which can be set in the menu. When exceeded these thresholds cause the
instrument to stop the integral calculation.
The HD2102.2 instrument is a datalogger. It memorizes up to 38,000 samples with single probes
and 14,000 with combined probes. Data can be transferred from the instrument connected to a PC
via the RS232C serial port or USB 2.0 port. The storing interval, printing, and baud rate can be
configured using the menu.
The HD2102.1 and HD2102.2 models are fitted with an RS232C serial port and can transfer the
acquired measurements in real time to a PC or to a portable printer.
The Max, Min and Avg function calculate the maximum, minimum or average values.
Other functions include: the relative measurement REL, the HOLD function, and the automatic
turning off that can also be disabled.
The instruments have IP66 protection degree.
This manual describes the HD2102.1 and HD2102.2 models: if not otherwise specified, the
description is intended to be applicable to both models.
