1. 2 5V your battery is nearing the end of it s service life Use ONLY 1 5V AAA batteries Calibration a Word about understanding magnetics MAG ic Probe uses magnets and magnetic sensors to measure the thickness of any non ferrous materials This technique is very effective because magnetic fields can penetrate these materials with no attenuation or deformation However as with most technologies some tolerance and knowledge is required for achieving the best results e Magnetic fields generated by permanent magnets are very strong at the magnet surface but deteriorate very rapidly in a non linear manner as the distance increases e Magnetic fields vary with temperature even fractions of a degree will have an effect e Magnetic sensors also vary their output with temperature and suffer from internal fluctuations e Friction of the magnet on the material surface may cause it to not be centered on the probe tip when moving the probe across the measured object e Dust and surface anomalies may cause the probe to be off perpendicular with regards to the external magnet e Magnetic fields are affected by metallic objects and even the Earths magnetic field can influence your measurements Considering the above and following the usage recommendations will enable you to get the most out of your MAG ic Probe MAG ic Probe is supplied with 2 magnets The 72 ball provides the strongest magnetic field and thus the highest resolution an2. way the zero 0 00 value would include the paper thickness and all measurements must be performed with the paper included You can also use the OFFSET function in the MAG ic Probe Software to compensate for a thicker protective cloth if required MAG ic Probe Device Overview MAG ic Probe V5 0 is the newest variation of the MAG ic Probe product line It should be very intuitive to operate as all instructions are displayed on the LCD display The device features e a connection socket for the Sensor Probe e a USB connection for external power and connection to a computer for use with the MAG ic Probe Software e a3 position power switch Battery OFF Battery ON and INFO Mode e a Crisp LCD Display Screen e Vent slots for temperature stabilization Notice Never turn the power switch ON OR connect to the USB of a computer without FIRST attaching the sensor probe to the device When attaching the Sensor Probe please ensure that the sensor plug is FULLY seated in the connector a poorly inserted plug may Cause severe damage Never remove the sensor probe whilst the device is powered ON Do not apply excessive pressure to the LCD window the LCD is fragile and should be treated with care Try to minimize dust entering the device and store it in the supplied shipping box Operating Instructions IMPORTANT First attach the Sensor Probe to the device BEFORE attempting to power ON or connect to a computer via USB MAG ic Probe

7. be makes approximately 100 measurements per second but uses an advanced internal algorithm to average out the readings to ensure a smoother display and more stable output This is the reason that the change in displayed values will seem to LAG behind rapid changes made between the probe and magnet Consequently it is important that you pause at every measuring location to allow the output reading to stabilize This should also be considered when using the HOLD mode in the MAG ic Probe Software Turn OFF the unit when not in use to conserve battery life Take care of the magnets they are fragile and will shatter or splinter if allowed to snap onto each other or metal objects Ensure your instrument does not contain any metallic objects to which the internal magnets can be attracted Removing a magnet from a finished instrument can be difficult Do not drag the probe across finished surfaces Either lift the probe slightly from the surface before moving to a new location or insert a protective material under the probe before moving Use the larger magnet if possible This will provide the highest resolution because of a stronger magnetic field Only connect and remove the Probe connector when the unit is completely powered off If this is attempted while the unit is powered damage may occur Avoid temperature changes after calibration Battery Replacement MAG ic Probe V5 0 uses 2 x AAA 1 5V batteries Slide the back over off to reveal batte
8. d should always be your first choice The smaller magnet should only be used when access to the inside of a finished instrument is limited due to small f holes etc for example violins and mandolins On startup MAG ic Probe provides a calibration sequence to detect the magnet size and to compensate for small variations in field measurement tolerances like temperature and location This initial calibration is suitable for most quick measurements for example when you are making a few measurements during shaping or sanding and then re measuring periodically This basic calibration can and should be repeated often if conditions change by simply turning the device OFF and ON again OR when using USB and the MAG ic Probe Software by selecting the CALIBRATE option Advanced Calibration a More advanced calibration sequence is advised for prolonged measurement sessione Advanced Calibration Continued Temperature variation is the biggest enemy of electronic measurement Even the heat generated by a human hand will heat the probe enough to affect your measurements However the maximum effect this would probably have on measurements is in the order of 0 1mm 0 2mm 4mil 8mil If this is important to you please read on When preparing for a more serious prolonged measuring session such as mapping a complete top or plate with many measurements a two step calibration sequence is advised The goal of this 2 step process is to onl
