shes. During the RCD phase the AUTO- POWER-OFF function is disabled, that is the instrument does not swit- ch off automatically. To switch off, press the ON/OFF key. If the stored data are not reset they remain in the memory until REC is pressed again.
When the MAN key is pressed the user chooses what scale to operate on. There are 4 scales available, except for temperature measure- ment where there are 2. When this key is pressed the Q Energy integration time that has elapsed since the REC key was pressed appears on the display in seconds, minutes or hours.
if a high value is to be set. This key has two functions; in the first, when Q is set, it increases the value; the second function enables the serial output. When the key is pressed only once, the figure shown on the display is sent to the serial output.
ENGLISH – 31 – PROBE CONNECTION The HD 9021 may be fitted with either one or two probes; the instrument has two DIN 45326 8-pole inputs, input A and input B.
The light emitted by a lamp varies with the square of the current, so there may very well be variations in values during the test which the human eye does not detect. When measuring temperature choose the probe most suited for the case: immersion, penetration or surface probes.
LOW BATTERY WARNING If the battery voltage falls below acceptable levels, a beep sounds every 30 seconds and the symbol appears. From that moment there remains about 1 hour autonomous operation, however the battery should be replaced as soon as possible.
MAINTENANCE Storage conditions. * Temperature: -20 to +60°C * Humidity: less than 85% relative humidity. * Do not store the instrument in places where: 1 - There is a high degree of humidity. 2 - The instrument is exposed to direct sunlight. 3 - The instrument is exposed to a source of high temperature.
ANALOG OUTPUT It is possible to link up with the SUB D male 9-pole connector of the instru- ment to obtain an analog output: ENGLISH – 35 – DTE DCE AD RS 232C - Data communication equipment - Data.

CALIBRATING THE INSTRUMENT HD 9021 1) Open the instrument. 2) Connect the prods of a precision meter to the following pins on the input A (or B) connector: the positive to pin 7 (V+) and the negative to pin 6 (GND). 3) With the instrument and the meter switched on, turn the trimmer TR1 until the display on the meter indicates 4Vdc.
ENGLISH – 39 – CHARACTERISTICS - Microprocessor-controlled multifunction quantum-photo-radiometric indi- cator with LCD indication for measuring sources of light and temperature. Measures ILLUMINANCE (lux, foot-candle), IRRADIANCE (W/m 2 ) and RADIANCE (cd/m 2 ).
- Display: LCD 12 mm, function and photo-radiometric symbols. - Functions: Automatic and manual change of scale, integration time up to 1999 hours, auto power off. Storage and updating of the Maximum, Minimum and Q (Energy) values. Optoinsulated serial output RS232C with adapter AD RS232C.
ORDER CODE HD 9021 K : The kit is composed of the HD 9021 instrument, diplomatic carrying case, without probe. HD 9021 : Photometric probe for measuring light, illuminance , photopic PHOT/C correction filter complying with CIE, diffuser for cosine correc- tion.
PROBES The primary purpose of the probes is to detect and measure light in its various aspects; for this reason there are different probes available to suit the different requirements. Probes are required for measuring illuminance (lux, foot-candle), irradiance (W/m 2 ) and luminance (cd/m 2 ).
HD 9021 RAD/C Radiometric probe for measuring the IRRADIANCE of light sources, irra- diance of the sun, etc. Radiometric filter and diffuser for angle correction according to the cosine law. Spectral measurement range 400÷ 900 nm, range from 1 microwatt/cm 2 to 200 milliwatt/cm 2 .
The typical response curve of the probe is as follows: The study and field of application of ultraviolet rays has seen considerable growth in the last decades. The ultraviolet field is conventionally subdivi- ded into the following three "bands": - the band between the wavelengths from 400 to 315 nm.
UVC rays are useful thanks to their bactericide and ozonizing capacity, so they are used in the field of sterilization; another field of application that is being developed is in the polymerization of adhesives or resins (photoresi- st); as a drawback they cause more serious cases of erythema and conjunctivitis than UVB rays.
HD 9021 UVB Radiometric probe for measuring radiation power, IRRADIANCE , in the UVB wave length 280÷ 315 nm, peak at 312 nm. Quartz diffuser for cosine correction.
– 47 – HD 9021/Cd Probe for measuring LUMINANCE , measuring range from 0 to 1999x10 3 candles/cm 2 . Measuring angle 6° with opening surface 25 mm.
