1. GAL 3L offer the best combination with the widest possible measuring range EXTERNAL FEATURES AND CONTROLS Fig 3 indicates the layout and function of the switches and connectors and other features available on the light metres The ON OFF switch A in Fig 3 is located on the left side of the meter housing To switch ON move it forward The meter is OFF when the switch is in the lower position The HOLD button B in Fig 3 can be used to freeze the display for convenient reading by the operator This hold button operation can be achieved for up to 5m distance from the instrument by means of a remote hold cable optional extra plugged into connector C in Fig 3 A simple contact closure between the two mono plug connector pins activates the hold freeze function The ANALOG OUTPUT of the meter is D in Fig 3 It can be used to supply a 2V output for a full scale reading It has an output impedance of 10 kS and can be used to record light levels on a chart recorder or any other suitable data acquisition system A stereo plug should be used to connect the equipment to the analog output socket OPERATING INSTRUCTIONS 1 Remove the instrument from its case and mount or place it in the desired measurement position has been disabled Return instrument for repair if zero reading cannot be obtained d If required the reading is adjusted by turning the potentiometer P1 as indicated on the rear label of the probe until the reading is2. correct e Set the probe range factor to the higher range factor and adjust P2 as marked on the rear label until a reading of exactly 10 times lower is achieved than with the selector switch in the lowest range factor setting f For probes with integral dose option e g GALP 2L please refer to the manufacturer This range has been discontinued in favour of a microprocessor range of instrumentation g To make the adjustments on the potentiometers P1 and P2 it is necessary to pierce the rear label of the probe Seal again with suitable plastic stickers after the calibration is completed NOTE Calibrations should only be performed by trained metrologists in a recognized calibration laboratory SPECIFICATIONS Measurement parameter Illuminance Dynamic range 1 200 000 Readout 4 digit LCD display Power source 9V type PP3 battery Battery life approximately 200 hours for alkaline battery Detector Silicon photodiode with photo metric filtering Angular response As indicated in Fig 1 nominal values Spectral response As indicated in Fig 2 nominal values Mass Display unit 220 g Accessories Protective cover for detector instruction manual Re calibration Return unit to a recognized calibration laboratory for re calibration every 12 18 months depending on frequency of usage or if cali bration is in doubt for any reason 3 distributor to the manufacturer shall be paid by the approved
3. type for which the calibration is desired Alternatively produce a stable illuminance with a suitable light source of the desired type and measure it with a calibrated light meter c Adjust the meter with the calibration adjustment F in Fig 3 until it reads correctly d Seal the hole F in Fig 3 with a suitable calibration sticker 2 Probes a Plug the probe into the meter Set the probe s range selector switch A in Fig 4 to the lowest setting b With the dustcap firmly in place D in Fig 4 check the meter reading of zero The potentiometer P5 indicated on the rear label of the probe 2 GENERAL DESCRIPTION The GOLDILUX series of light meters are designed to measure illuminance of the visible spectral radiation in the units of lux or optionally in footcandles An external probe may be plugged into a light meter In this case the detector in the light meter is automatically disconnected and the displayed reading corresponds to the quantity and the units measured with the probe The liquid crystal display of the metres GAL 2L GAL 2H is autoranging over one decade External probes e g GALP 1L have a built in probe gain selector switch with two different gains and thus cover a wider measuring range than the meters with built in detector The probe gain settings are multiplied as indicated on the probe labels and the switch setting indicated by the probe range factor Probes combined with a non specific meter display

P probes with special reference to GBIL 1L GENERAL DESCRIPTION EXTERNAL FEATURES AND CONTROLS OPERATING INSTRUCTIONS MAINTENANCE AND PRECAUTIONS CALIBRATION SPECIFICATIONS WARRANTY INFORMATION 2 Switch on the instrument and check its zero with the cap firmly on the detector Should it be necessary to adjust the meter reading to zero e g for calibration purposes adjust it via the potentiometer accessible through the latch opening in the open battery compartment 3 Remove the protective cap from the detector being used 4 Take readings Check on the units Kilolux or lux or footcandles as indicated by the label N B A 9V battery is necessary for operating the instrument and this has to be inserted in the battery compartment at the back of the meter as shown in Fig 3 MAINTENANCE AND PRECAUTIONS When not in use always put the protective cap on the detector and keep the instrument in a safe place There is a warning battery low on the LCD display when the 9V battery needs to be replaced If necessary clean the detector with a soft clean cloth or tissue moistened with alcohol Dry and polish lightly with a dry tissue CALIBRATION 1 Meters a Meters with a built in detector e g GAL 2L adjust the meter reading to zero via the potentiometer accessible through the opening in the open battery compartment and the cap firmly on the detector b Expose meter to a known illuminance emitted by a light source of the
5. PROBES FOR BLUE LIGHT MEASUREMENT The GOLDILUX Bilirubin Phototherapy Meter GBIL 1L has been designed for the accurate measurement of the amount of therapeutically effective blue light used for the treatment of hyperbilirubinemia or neo natal jaundice The probe detector matches the photooxidation response of Bilirubin in the blood of jaundiced neonates This response has been shown to be most pronounced in a wavelength region from 400 to 500 nm with a maximum at 450 nm For effective treatment the amount of therapeutically effective blue light to which the infant is exposed should be in the order of 5 10 uW cm The quantity in units of uW cm is the therapeutically effective power from the lamp in uW falling on each square centimetre of skin of the infant The length of the exposure of the infant to the blue light depends on the age and condition of the baby its response to the exposure and other factors as determined by the responsible physician The factory calibration of the probe was performed at a distance of 800 mm from a spectroradiometrically calibrated phototherapy lamp and at a level of approximately 40 uW cm The lamp had a peak output at a wavelength of 450 nm In order to ensure continued accurate readings from the probe it should be re calibrated by a competent calibration laboratory at suitable intervals yearly or as determined in accordance with the company quality system or as specified in applicable Govern
