GENERAL CHARACTERISTICS The Photo-Radiometer HD2302.0 is a portable instrument, fitted with a large LCD display for visualization of the measured data. It measures: • illuminance; • luminance; • PAR; • irradiance (across VIS-NIR, UVA, UVB and UVC spectral regions or in the measured effective irradiance according to the UV action curve).

HD2302.0 1. Input for probes, 8-pole DIN45326 connector. 2. Battery symbol: displays the battery charge level. 3. Function indicators. 4. Secondary display line. 5. DATA key: displays the maximum (MAX), the minimum (MIN) and the average (AVG) of current measurements.
DESCRIPTION OF THE FUNCTIONS The Photo-Radiometer Model HD2302.0 keyboard is composed of single-function keys, except the ON-OFF/Auto-OFF key that has two functions (see the description of the key below). The pressing of a key is accompanied by a short confirmation "beep": a longer "beep"...

CLR key It resets the maximum, average, and minimum value of the captured measurements. DATA key By pressing this key once the maximum (MAX) value of the measurements captured by the probe connected to the instrument is displayed, updating it with the acquisition of new samples.
PROBES AND MEASUREMENTS The instrument works with probes of the LP471… series: these are photometric and radiometric probes that measure: • illuminance (LP471PHOT), • irradianace (LP471RAD, LP471UVA, LP471UVB, LP471UVC and LP471UVBC), • PAR (LP471PAR and LP471PAR02), • luminance (LP471LUM2), • effective irradiance in the spectral range of blue light (LP471BLUE), •...
LP471P-A OMBINED PROBE LP471P-A is a two sensors combined probe with SICRAM module for measuring illuminance (lux) with standard photopic spectral response and irradiance (μW/cm in UVA spectral range (315...400 nm, with peak at 365 nm). The probe also provides the ratio of UVA irradiance and illuminance in µW/lumen (quantity of interest in the museums field).
INSTRUMENT SIGNALS AND FAULTS The following table lists all of the indications displayed by the instrument in different operating and error situations. Display indications Description Indication of insufficient battery charge: it appears when you BATT TOO LOW turn the instrument on. The instrument issues a long beep and CHNG NOW turns off.
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. If you continue to use it, the instrument can no longer ensure correct measurement.
WARNINGS 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.
