Key Features

Here are a few of the features of the MicroPower:

• Logs pack current to +/- 100 amps and voltage from about 4.5 volts to 45 volts
• Current is measured with a true Hall Effects Sensor - NOT a resistance shunt like other units on the market!
• Great for bench monitoring of battery charging also!
• Accepts optional inexpensive sensors for Temperature, RPM (brushless, magnetic or optical), Airspeed, Altitude,

Servo Current, Throttle Movement, and more, available below

• All data is logged to permanent memory, which retains the data even when the power is removed
• Software computes Wattage, mAH, etc. for complete e-flight data.
• Fully Compatible with Windows Vista, 98SE, ME, Win2K and XP™
• Integrated USB with included cable (NOT a USB to serial port cable like other loggers)
• Supports simultaneous Temp and RPM sensors, or two Temps
• Weighs about 0.5 oz (17 grams). Version with Wire Leads weighs slightly more.
• Supports USB Live Mode, which lets you see what's happening in the model LIVE on the bench, on your PC
• Adjustable logging rate (1-10 samples/second) and lossless data compression for long log times
• Comes with our state of the art Windows virtual playback display and graphing
• Powerful Graphing software has advanced charting features, such as amps vs volts
