ENGLISH Key Symbols lit besides the numbers Description All the symbols are lit for a few seconds after switching on. Key for switching the instrument on and off. The instrument switches off automatically about 8 minutes after this key has been pressed, as it has a built-in switch-off device. If any key other than the ON/OFF key is pressed, the instrument switches off 8 minutes after the last key was pressed.
ENGLISH Key Symbols lit besides the numbers Description shes. During the RCD phase the AUTOPOWER-OFF function is disabled, that is the instrument does not switch 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.
ENGLISH Symbols lit besides the numbers Key Description When the MAN key is pressed the user chooses what scale to operate on. There are 4 scales available, except for temperature measurement where there are 2. s m h 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. To quit the routine, press the key for the channel in which the reading is being taken.
ENGLISH Symbols lit besides the numbers Key Description 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. If the key is pressed for more than three seconds the continuous serial output is enabled; this means that what is shown on the display is sent continuously to the serial output every 10 seconds.
ENGLISH Symbols lit besides the numbers Key Description Err If the probe is not connected to the instrument when it is switched on, or if there is a break in the probe, the "Err" message appears. E1 This message appears on the display when the user tries to obtain the difference between inputs A and B when two probes of different types are connected. OFL This symbol appears on the display when the reading is out of scale.
ENGLISH 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.
ENGLISH LOW BATTERY WARNING If the battery voltage falls below acceptable levels, a beep sounds every 30 seconds and the H symbol appears. From that moment there remains about 1 hour autonomous operation, however the battery should be replaced as soon as possible. To change the battery turn the screw on the door of the battery compartment in an anti-clockwise direction.
ENGLISH MAINTENANCE Storage conditions. -20 to +60°C * Temperature: less than 85% relative humidity. * Humidity: store the instrument in places where: * Do not 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. 4 - There are strong vibrations. 5 - There is steam, salt and/or corrosive gas. The instrument body is made of plastic so it must not be cleaned with solvents which can spoil plastic.

ENGLISH 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/m2) and luminance (cd/m2). Each sensor has its own work band completed by filters or diffusors which correct or limit its range. The size of the silicon sensor used in the various probes is 7.34 mm2.
ENGLISH HD 9021 RAD/C Radiometric probe for measuring the IRRADIANCE of light sources, irradiance 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/cm2 to 200 milliwatt/cm2. The probe is used in greenhouses for measuring the power of artificial light, shade, the performance of solar panels, solar heating plants, solar filters, etc. The typical response curve of the probe is as follows: 1.00 0.
ENGLISH The typical response curve of the probe is as follows: 1.00 0.89 0.78 0.67 0.56 0.44 0.33 0.22 0.11 900.0 850.0 800.0 750.0 700.0 650.0 600.0 550.0 500.5 450.0 400.0 0.00 The study and field of application of ultraviolet rays has seen considerable growth in the last decades. The ultraviolet field is conventionally subdivided into the following three "bands": - the band between the wavelengths from 400 to 315 nm.
ENGLISH 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 (photoresist); as a drawback they cause more serious cases of erythema and conjunctivitis than UVB rays.
