MicroPower readings to your other meter s readings if desired This is done by choosing Tools Calibrate Pack Voltage and Amperage and entering the values your meter reads and the MicroPower reads If you don t desire to change the calibration on say voltage but wish to change it for amperage just leave the voltage fields as 0 and the calibration for voltage will not change e Ifthe MicroPower appears to be reading highly inaccurate voltages or currents the first thing to try is to clear all calibration This is done running the calibration tool as described above but entering the same values for the problem measurement For example if amperage is way off enter the same value say 5 0 for both the MicroPower amperage and the my other meter amperage which will clear all internal and user calibration Issue the temperature appears to be logged incorrectly Solutions e Make sure that the parameters you wish to log are checked under Tools Choose Parameters to be logged in Recorder e Itis normal for the Temperature 2 channel to have a wider spacing between temperature readings at room temperature than the temperature 1 channel This largely disappears when temperature exceeds 100 degrees F MicroPower Specifications Voltage Measurement approx 5V to 45V Voltage Resolution 0 1V Current Measurement up to 100 Amps Current Resolution 0 1 Amp Current Draw approx 35 mA Weight Unit with Integrated Connectors app

6. mount one of the magnets total To flush mount the magnets drill a hole just slightly larger than the diameter of the magnet size you choose and of the same depth as that magnet If you decide to surface mount the magnets thoroughly clean this area and lightly scuff it to improve adhesion Glue the magnets with the side marked with a red line facing inward hidden using epoxy or other strong suitable glue It s important that the red line on the magnets faces away from the sensor once the sensor is installed The magnets should be glued 180 degrees apart to keep the shaft in balance WARNING make sure that the magnets are glued sufficiently so that they will not detach and create a hazard and always wear safety glasses when your motor is running Itis also a good idea to put a piece of heatshrink tubing or electrical tape around the magnets to further secure them Using Existing Magnets Note if your motor already has magnets mounted for some other purpose there s a good chance you can use them Take one of the magnets included with the RPM sensor kit and put that magnet up against the previously mounted magnet If the red line of the MicroPower magnet faces down so that the sensor can be mounted facing the side of the magnet with no red line mount the sensor with the printed side toward the magnet If the side of the magnet with the red line is visible when on top of the previous magnet the polarity is reversed This should work correct

8. Tree Systems LLC Page 3 To install our magnets first find a suitable location on your motor or drivetrain to attach either one or two small magnets and RPM sensor Typically the prop washer or prop hub are ideal locations for planes and the car s axle shaft is good for car installation This will of course vary with the construction of the model Make sure the magnets are mounted on some structure that doesn t flop around as the magnets could hit the sensor in this case The RPM sensor must be mounted so that it does not move around and is within 1 2 mm of the two magnets as they spin On typical plane installations there s usually a place where the back of the sensor can be glued to a flat surface under or over the hub which has the magnets mounted The RPM sensor kit includes four magnets That provides you with up to 3 spares Installing Magnets Once you have determined where to install the magnets decide whether you will drill a hole so that the magnets will mount flush with the surface or if you will just glue the magnets to the surface Though somewhat more difficult and permanent mounting the magnet flush with the surface is the best long term approach since the mounting will be much more rugged and the risk of imbalance due to not mounting the magnets exactly 180 degrees apart is reduced In fact if the magnet is mounted flush in another metal material it is quite possible that no shaft imbalance will occur if you only
