6. The probes measure ultraviolet radiation in units of uW cm Please consult Fig 2 for choosing the right probe in the appropriate spectral region When you plug a probe into a micro processor controlled MP series display unit the microprocessor first reads all the relevant probe parameters from a memory circuit in the probe These parameters include probe serial number probe type units of measurement measuring range overall calibration factor range calibration factor for each probe amplification probe offset and calibration date Then it displays the measurements from the probe sensor in the selected units on the display unit s LCD display The microprocessor in the display unit also has full control over the gain switching circuits in the probe and will autorange the probe if autoranging mode is selected over its full measuring range The GOLDILUX series of ultraviolet probes measure IR in the probe and the last selected unit will thus be used automatically selection is made press the UNITS key again to go back to measuring mode The unit selected continues on the display instrument after switching off and on again 4 The main probe parameters are displayed in a series of consecutive screens on the LCD display whenever the PROBE ID key is pressed 5 In case of a dose measurement press the NORMAL DOSE key on the display unit and toggle through the available choices of integration time by using the UP and DOWN
