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 c ...

V2.3 KEYBOARD AND MENU DESCRIPTION Foreword The instrument keyboard is composed of single-function keys, like the SERIAL key in the HD2102.1 model, 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 men ...

V2.3 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. The acquisition frequency ...

V2.3 THE PROBES The instrument works with photometric and radiometric probes of the LP471… series that measure: • illuminance (LP 471 PHOT), • irradiance (LP 471 RAD, LP 471 UVA, LP 471 UVB and LP 471 UVC), • PAR (LP 471 PAR), • luminance (LP471 LUM 2) • effective irradiance according to the UV action curve (LP 471 ERY), • effective irradiance in the spectral range of blue light (LP 471 BLUE), • illuminance, UVA irradiance ...

V2.3 COMBINED PROBE LP 471 P-A LP 471 P-A is a two sensors combined probe with SICRAM module for measuring illuminance (lux) with standard photopic spectral response and irradiance (μW/cm2) in UVA spectral range (315...400 nm, with peak at 365 nm). Moreover probe provides the ratio of UVA irradiance and illuminance in µW/lumen (quantity of interest in the museums field). Both sensors are equipped with diffuser for the correction accordi ...

V2.3 PROBE LP 471 SILICON-PYRA LP 471 Silicon-PYRA measures the global solar radiation using a silicon photodiode in the spectral range 400…1100 nm. The particular geometry and the diffuser allows the sensor to have a field of view of 180° according to the cosine law. The probe is suitable for the measurement of natural sunlight. Under overcast skies, or for reflected light measurements the use of a thermopile pyranometer is recommend ...

V2.3 Q/TIME INTEGRATION In addition to instantaneous measurement, the instrument calculates the following summation: (1) Q(t) = u(t) t, Σ ⋅Δ Δt = 1sec 0 t where u(t) is the instantaneous value of the input variable compared to time t. The sampling interval is fixed at 1 second. As soon as either the Q(t) value or the integration time t reach the set limit, the integration is stopped. Maximum integration time: 100 hours, 00 minute ...

V2.3 WARNINGS AND OPERATING INSTRUCTIONS 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 measureme ...
