ENGLISH – 27 – Symbols lit besides the numbers Key Description All the symbols are lit for a few seconds after switching on. lx/fcd °C/°F RCD 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 [...]

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 key is pressed for the first time it starts storing data in the memory, the second time [...]

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. To quit the routine, press the key for[...]

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[...]

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. If only one input is used, be careful when using the keys for input A or B. The instrument recognizes the type of probe connected, which is distingui- shed by a suitable code; it then gets[...]

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. It is sufficient to immerse the probe in the liquid of which you want t[...]

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. To change the battery turn the screw on the door of the battery compartment in an anti-clockwis[...]

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. 4 - There are strong vibrations. 5 - There i[...]

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 ). Each sensor has its own work band completed by filters[...]

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. which includes radiations defined as t[...]

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. Depending on the effec[...]
