Key Features
Here are a few of the features of the eLogger:
• Logs pack current to +/- 100 amps (150 amps with MPRV4-LEADS-150) and voltage from about 5 volts to 80
volts
• Current is measured with a true Hall Effects Sensor - NOT a power robbing resistance shunt
• Adjustable logging rate (from 50 samples per second to one sample every 5 minutes)
• 16 times the logging space of the standard eLogger V3, and lossless data compression. Typically logs all
available sensors for about four hours, at 10Hz.
• All data are logged to permanent memory, which retains the data even when the power is removed
• Fully compatible with our OSD Pro expander
• Includes Y cable for throttle position logging
• Great for bench monitoring of battery charging also!
• Supports the PowerPanel LCD Display
• Accepts optional inexpensive sensors for three Temperatures, RPM (brushless, magnetic or optical), Airspeed,
Altitude, GPS, Servo Current, and more
• Software computes Wattage, mAH, etc. for complete e-flight data.
• Fully Compatible with Windows 7 (32 and 64 bit), Vista, 98SE, ME, Win2K and XP™
• Weighs about 0.8 oz (22 grams). Versions with Wire Leads may weigh slightly more.
• Comes with our state of the art Windows virtual playback display and graphing software
• Powerful Graphing software has advanced charting features, such as amps vs. volts
• Internet Updatable firmware - as we add new features or (heaven forbid) have a firmware bug, the update is just a
download away! No need to ship hardware back and forth.
• Full support for English and Metric units.
• Software has built in English, German and Chinese languages.
