SafetyMaster - Wattmeter up to 10A

SafetyMaster is a unique measuring device - from 0.1 to 10.0 A power meter with digital and graphical display - helping you to reliably examine how well the system is power for your RC models. "Soft" batteries and "sickly" BEC stabilizers are often the "weakest link" on-board electronics and a major cause of accidents. SafetyMasterem to see how secure your power system - by measuring current drawn by the servos and receiver and by monitoring the battery voltage stabilizer or BEC load. Not only that, besides the reading of the instantaneous value of current SafetyMaster allows you to view the progress of the current drawn as a graph, depending on the time! Lightweight (just 14 g) and dimensions in the palm even allow SafetyMaster put aboard a "shoot" course taking on-board network or just one servo per flight or drive! In your hand so you get a sophisticated measuring device - graphic analyzer, with whom he reviewed an on-board sampling of all parts of the RC equipment like never before! At rest home workshop, as well as "field conditions" at the airport, without having to drag along a computer or other expensive equipment for displaying the current waveform.

SafetyMaster is of course also possible to use for metering small propulsion systems (up to 10 A and a voltage of 8.4 V - i.e. 2s Li-Po).

SafetyMaster is stored in a small flat housing with a dominating LCD display on the front panel. On the top side are located the inlet and outlet sockets for the standard three servokonektory into which connects the power source and "appliance". There are also three buttons used to navigate through menus and setting thresholds of current and voltage warnings.

For basic measurements of current consumption is input socket connects the power source (battery or receiver servokablík electronic speed controller with BEC power stabilizer) out jack connects servokablík leading into the power or throttle channel receiver. SafetyMaster transmits servo control, so you can connect it for metering individual servos - in this case, the input power meter to engage in the corresponding channel receiver and its output connects measured servo.

Press the button to select the three main menus:

• Main menu with digital display instantaneous current, voltage, input / output, measured maximum current and minimum voltage measured
• Menu of the graphical display with a graphical display of the course of current versus time and a digital display of the elapsed time and flown charge in mAh
• Menu alarm messages with adjustable thresholds, maximum current and minimum voltage for alarm. Here you can also reset the current record and start from scratch as a new video recording and measuring the flowed charge.

Thanks configurable thresholds for current and voltage SafetyMaster you will immediately warn when the current consumption exceeds a certain limit or threshold voltage drops dangerously - whether due to the large, current consumption, "consumers" or too "soft" power source.

SafetyMaster kit contains: SafetyMaster power meter, three-wire measurement cable with servokonektory at both ends, instructions.

Practical use SafetyMasteru - understanding the measured values:

• 1) You can start by measuring a subscription-board RC equipment in all your models. Observe that when moving a greater number of servos current consumption approaching maximum capacity BEC stabilizer in your speed controller or receiver if the voltage of the battery significantly decreasing (this would indicate that the used receiver battery can not provide enough power, it is a "soft").
• 2) If you find strikingly large collection of servos, check one after the other, whether it's a problem all servos or just one. Keep in mind that the servos high tension, digital servos and servos with a strikingly high tension in proportion to their size they have always 'nature' higher consumption.
• 3) Measure News servos connected with a rod and a wheel and measure also taking servo itself - if the current consumption of the servo itself is considerably lower, suggests that somewhere scrubs, you have too much resistance in the cables, rudder hinges go stiff, etc .; with giant models will think about it useful to add static balancing rudders, if rudder servos controlled more work on their better alignment ...
• 4) When the measurements of airborne equipment supplied from BEC stabilizer watch carefully the current value. When moving all the servos current consumption of electronics not in any case exceed 50-70% of the nominal value (ie. Eg. 1.0 to 1.4 A at 2 A stabilizer BEC) in the case of linear stabilizer, or 80-90 % of nominal (i.e. e.g. from 2.4 to 2.7 A for 3 A stabilizer SBEC), the case of switching stabilizer.
• 5) When the measurements of airborne equipment supplied from BEC voltage stabilizer and watch. When moving all the servos voltage stabilizer should not in any case fall to less than 90% of the nominal value (ie. Eg. 4.5 V voltage at 5.0V BEC). But if you want to be really sure, you should consider a stronger power source, if the voltage stabilizer BEC drops by more than 0.1 V.
• 6) When the measurements of airborne equipment and receiver battery-powered watch carefully the current value. When moving all the servos current consumption of electronics not in any case exceed 95% of the nominal current carrying capacity of the type of articles (of course assuming measurements on a fully charged battery).
• 7) When the measurements of airborne equipment and receiver battery-powered watch and tension. When moving all the servos voltage stabilizer should not in any case fall to less than 1.15 to 1.20 volts per cell for NiCd / NiMH batteries, 3.7 to 3.8 V per cell for LiPo batteries and 3.3 V article for LiFe batteries (of course assuming measurements on a fully charged battery).
