i-Meter 7 in 1 Multi Meter
Very Cool

The most useful tool EVER for your toolbox or shop

This incredibly versatile device will quickly become your favorite diagnostic and testing tool. The Battery Checker function allows you to check the charge and balance state of your LiPo/LiFe/LiIon battey packs, never again start a flight with a partially charged battery.

The Watt Meter function helps you optimize your power system for top performance. It retains the peak current and peak wattage readings for easy reference after a test.

The Internal Resistance function lets you see the state of the individual cells in your battery packs. Not getting the performance out of your packs that you should? This can help you identify the problem and monitor your packs over time.

The Tachometer can measure the RPM of your 2 to 5 bladed props. Are you achieving the revs that you expect? Temperature sensor can tell you if a component is generating too much heat, the peak reading is retained.

The Servo Tester function is great for centering your servos during the build or testing the range and cycling for break-in. This feature can also be used to run an ESC when doing motor tests all without the need for a receiver or transmitter.

The Thrust Calculator helps you determine whether your overall system is the right match for your project.

• Battery Checker - Check individual cell voltages, total pack voltage, pack balance, 1-8 cells
• Internal Resistance - Check and compare the internal resistance of individual cells
• Watt Meter - Measure Current (Amps), Peak Current, Voltage (Volts), Power (Watts), Peak Watts, Energy (Watt-Hours) and Charge (Amp-Hours) in real time
• Servo Tester - Test and cycle servos manually or automatically
• Tachometer - Optical Tach for 1-5 Blade Props to 60,000 RPM

• Thrust Calculator - Estimate thrust with values you enter

Unit includes:

• 2 sets of 12AWG silicone wires with 6mm gold plated male plugs on one end the other end is ready for the connector of your choice.
• 1 test lead with 6mm gold plated male connectors and a 2 pin male plug for cell resistance testing.
• A 20 in. lead with temperature sensor.
• English instruction manual.

Cliff's Notes: The i-Meter is a very useful tool for measuring and understanding the condition of your valuable LiPo batteries, but to use it effectively and to prevent damage to the battery or the i-Meter, it is essential that you read and fully understand the well written instructions before you begin to use the i-Meter to analyze your power system.

Also, the i-Meter will not balance a LiPo battery pack. It accurately measures the voltages in each of the pack's cells and displays all the voltages simultaneously on the LCD screen so that you know whether the pack is balanced, or not. A separate balancer or balancing charger is required to equalize the voltages in the cells of an unbalanced pack.

Don't forget to peel the thin, clear piece of vinyl film off the face of the LCD panel. It's there for protection, but it makes the screen harder to read.

Finally, batteries having a ThunderPower-style balancing connector, with 2mm pin spacing, will need an adapter in order to connect that battery to the i-Meter.

SPECIAL NOTE: One of the capabilities of the i-Meter is the ability to measure the internal resistance of the individual cells in a Lithium Polymer battery pack. The well written instruction manual describes the process beginning on page 8. When measuring cell resistance, certain precautions must be observed in order to prevent permanent damage to the battery being tested and to the i-Meter. The precautions are listed on page 10, and are repeated here:

1. Do not leave a cell connected to the i-Meter for more than five minutes.
2. Be aware that although the i-Meter only takes small samples from the battery pack, the voltage will be reduced. Make sure you check your pack balance.
3. Avoid plugging the cell in reverse polarity. The i-Meter can cope with a reversed connection for a few seconds but it's still better not to do it in the first place.
4. Do not connect more than 5V to the cell inputs, again, the IRM can cope for a few seconds but it's best not to do it!
