Pot hidde under label Current sensor calibration Calibrates current sensor and changes altitude to absolute from AGL the default The current sensor is calibrated at the factory and will not normally need attention If for any reason you swap current sensors or replace one then you need to re initialize it to remove any offset Expose the pot switch and have a small screwdriver ready to adjust it 1 Bind the telemetry unit to the transmitter with a suitable receiver as explained earlier Lemon Telemetry Instructions 11 Dec 14 2 Upon successful binding power off the telemetry receiver unit but leave the transmitter turned on Remove the bind plug 3 Turn the pot switch fully clockwise to the right 4 Plug the V I sensor and Temperature RPM sensor if required into the telemetry unit 5 Power on the telemetry with a flight pack attached to the sensor The green LED should become steady on within no more than 3 seconds This indicates the current sensor s bias calibration is completed successfully If the red LED is on the unit has failed to calibrate and you should try again from the beginning If bias calibration remains unsuccessful the unit is faulty 6 Turn off power to the receiver telemetry unit Adjust the pot switch to approximately the middle position and power on again to resume normal operation The green LED should then flash twice a second as usual Changing to absolute altitude readout As expl

3. in order to display height above ground level AGL which is what most people are looking for when they think of the height of a model the Lemon telemetry unit as delivered sets the altitude reading to zero every time power is connected The Lemon altimeter is quite accurate by hobby standards It is ambient temperature compensated but will have small errors due to internal noise onboard heating of the components and natural variation of atmospheric pressure during the flight It is normal for the height reading to fluctuate by up to 6ft 2m and this variation may increase during A forthcoming version of the telemetry unit will have an improved Signal Indicator function to give more useful and reliable results that range from 0 100 Lemon Telemetry Instructions 11 Dec 14 unusual weather conditions with rapidly changing conditions This is an inherent behavior of a pressure altimeter and not a fault of the unit Display in meters or feet is chosen in the telemetry setup screen Flight battery current is displayed on the same screen if you have the V I sensor connected Temperature The external temperature probe is accurate at room temperature to within 1 F or better The sensing element is a 10kNTC thermistor and maintains good accuracy at all temperatures The internal temperature reported by the unit when no external temperature sensor is plugged in may be a little higher due to heat dissipation on the board The reading can be dis

Without any additional sensors it will display receiver voltage RxV signal indicator A accurate height above ground level Alt and the internal temperature of the unit Temp The unit is supplied with two plug in sensors The first is an accurate external temperature probe which automatically replaces the internal temperature when connected and can be used to monitor LiPo pack or ESC temperature in flight The external temperature sensor also includes a sensor wire for measuring RPM from one of the motor wires Before using the RPM function please review its limitations as discussed on page 7 The second plug in sensor available with either Deans style T connectors or XT60 connectors measures flight power pack current and voltage The instantaneous readings are displayed on screen in the Amps and Volts fields In addition on Spektrum transmitters that provide a PowerBox display the cumulative number of mAh drawn from the flight pack and the pack voltage at higher resolution are displayed The displays may vary depending on the fields chosen in Telemetry Setup in the transmitter menu and on the capability of the transmitter itself for example the DX6 and DX7s do not display PowerBox The telemetry unit works with any Lemon DSM2 or DSMX protocol receiver that has bind connector pins This includes the 7 channel Stabilizer as well as the 6 channel DSMX protocol compatible receiver the 10 channel DSM2 protocol compatible receiver and

8. This is not a Lemon calibration issue but a consequence of the way in which Spektrum transmitters display the numbers Current calibration is limited by display fluctuation at minimum resolution The pack and receiver voltage however are only displayed to a resolution of 0 1V which is greater than calibration accuracy Consequently you need to choose between mid point calibration and lowest limit calibration if you are concerned about precision Mid point calibration The chart at right shows what is normally understood by calibration and is technically the truest representation of the voltage within the limit of the bispiayea 8 display The output follows the input accurately and the eae display changes from one reading to the next at the voltage half way between the two values 4 7 4 6 Hence with dropping voltage the display will change at 4s 46 47 4s 45 50 5 4 95 V from 5 0 to 4 9V Actual Voltage Lower limit calibration This is what you may choose to set if you want the voltage alarm to trigger as soon as that voltage is reached Using this approach at 4 90 V the display will change 5 1 from 5 0 to 4 9V In practice flight pack and receiver voltage alarms are intended to alert you to when the voltage has dropped to a critical level Lower limit calibration will do that a a whereas mid point calibration will not trigger the alarm re a until the voltage has dropped by another 0 05Volts 4 6 Bottom l

10. ained above the unit as supplied shows height above ground level AGL as this is what nearly all fliers understand by model height A ground level of zero is set every time power is connected to the telemetry unit If for any reason you want readout in absolute pressure altitude above sea level ASL rotate the pot switch fully anticlockwise with power off and leave it there The green LED will now be absent rather than flashing twice a second Since the displayed height is based on a standard sea level pressure of 1013 25 kPa for an accurate altitude reading you will need to apply a correction for current barometric pressure at your location Calibration The unit is calibrated at the factory and most users will simply use it as delivered However the firmware allows the user to fine tune the span value of the battery voltage and receiver voltage to the absolute correct level The current and consumption values can also be calibrated against a known accurate wattmeter or high current ammeter By enabling calibration mode on the telemetry unit you can use the pot hidden under the label to adjust the value displayed on the telemetry screen in real time to match that of an accurate meter Once calibrated the span value will be saved in EEPROM thus ensuring accurate measurement See the Appendix for a discussion of how the limited display resolution might affect this Unless you are sure you need to recalibrate your telemetry system it is advis
11. ctions 11 Dec 14 Additional Information Detailed information about the Lemon Telemetry Unit The Lemon Telemetry unit is not a copy of anything made by Spektrum but an original design that conforms to the Spektrum data transmission protocol and the DSM2 DSMxX radio protocols The Lemon unit differs from the Spektrum TM1000 4 telemetry unit both in construction and in the way it provides certain data Most obvious is that there is no display of the Fields H and F Holds and Frame loss nor are there packet loss indicators for the four possible receivers A B L and R These features are unique to Spektrum systems In their place Lemon provide a general Signal Indicator displayed in the A field that provides roughly similar data on the strength and reliability of the radio link The unit is significantly smaller than the Spektrum one and about half the weight It operates over an input voltage range of 3 45 to 7 2v Despite the 5 5V max written on the label Specifics The Lemon Telemetry unit uses an ATmega 88PA microprocessor and a 2 4Ghz transmitter to send data signals to your transmitter It synchronizes with the receiver via the bind connector so that it cannot interfere with the radio control link It reads the receiver voltage and the number of data packets successfully arriving at the receiver combines those with its own data from sensors and sends the whole lot to be displayed on the transmitter telemetry screen
