1. GOLDILUX M P SERIES COSINE CORRECTED ILLUMINANCE PROBES USER MANUAL The main probe parameters are displayed in a series of consecutive screens on the LCD display whenever the probe ID key is pressed 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 keys Then press the START STOP key on the display unit to start the dose integration over the selected time interval The accumulated dose and the elapsed time will be displayed simultaneously on the LCD display until the selected integration period has expired Then both the timer and the dose reading will be frozen in the display until either the START STOP key is pressed to commence another dose measurement or the NORMAL DOSE key is pressed twice to return to NORMAL measuring mode The MANUAL option allows the user to stat and stop integration time for the dose measurement Press START STOP key to start and press again to stop By pressing the AUX key in normal measuring mode the following additional instrument features can be selected by toggling through the various options with the UP and DOWN keys a Display of the ambient temperature in the display unit GENERAL DESCRIPTION The GOLDILUX MP series of illuminance probes must be used in conjunction with a GOLDILUX MP series model GRP readout unit The probes measure illuminance in either lux or footcandl2. serial port of PC c Switch on the display unit d With the cap firmly on the probe detector observe the probe zero and if necessary adjust it to zero by setting the Rel zero via the ZERO key on the display unit e Run a suitable serial communication programme like TERMINAL for WINDOWS or the one supplied with the display unit of the PC for details nor the required communications settings see the user manual of the display unit Switch the display until to RS232 mode one of the available AUX key selections f Expose the probe to a known illuminance from a light source of the type for which a calibration is desired OTHER FUNCTIONS The display unit s ZERO key toggles the unit between two zero modes Abs mode A D analog to digital converter zero readings are taken at regular intervals by the micro processor and subtracted from previous consequent probe readings In the other ZERO mode Rel the current probe reading is subtracted from subsequent probe readings when this function is selected Whenever Abs mode is entered or when the display unit is switched on the Rel offset value is re set to zero A permanent Rel offset can be introduced by storing a non zero value in the probe s PO probe offset parameter password required The main use of the PO feature is to ensure a zero reading on the display when measuring with the cap on the detector If you wou
