Multi-function meter i-Meter is a really intelligent companion for modelers dealing with models with electric drive! In one box you will find a pocket-sized devices and seven useful functions:

  • Meter battery voltage
  • Meter internal resistance of the battery
  • Wattmeter
  • Servotester
  • optical tachometer
  • contact thermometer
  • Calculation of static thrust

1. A full battery voltage

The meter is used to measure the voltage of each cell lithium batteries (LiPo, LiIon, LiFe) and 2-8 articles in the series. The display shows the individual cell voltages (with a resolution of 0.001 V), the voltage across the set, the value of the cell voltage with the lowest and highest voltage, in numerical and graphical form is indicated residual capacity and rate of compensation individual cells. Contact i-Meter has a pitch of 2.54 mm, and a direct connection service connector systems JST-EH, JST-XH and PolyQuest (PQ) with four or more articles. To connect 2-3S sets with plug PolyQuest you need an adapter as well as for a set of connectors ThunderPower / ThunderFlight (TP / TF), which have a contact pitch of 2 mm. You can use adapters for chargers Raytronic, Sky RC, RC System Graupner, Robbe etc. This measurement is well-Meter supplied from the battery being tested.

2. Ensure the meter internal resistance of the battery

The meter is used to measure the internal resistance of each cell lithium batteries (permissible max. Voltage on the measuring input is 5V). These are connected via the supplied cable with kotakty spacing of 2.54 mm directly into the service connector kit. With this measurement, you can easily compare the quality of your batteries (the lower internal resistance, the higher ampacity), check the properties of individual cells in the set and monitored continuously aging batteries (battery internal resistance increases over time). For measuring the need for power-Meter also connect an external source (eg. 2-8S LiPo battery).

3rd Wattmeter

DC power meter for simultaneous measurement of actual output / input, current, voltage, and totalized flow of electric charge. It is a very useful tool for every modeller, which operates models with electric drive. Can prevent damage to the motor, speed controller and batteries that provide the information necessary to make these devices work in a safe area of \u200b\u200boperational values. It also allows safe experimentation with different batteries, propellers, gear ratios etc. in order to optimize the propulsion system. With its help, you can measure battery capacity, measured load receiver battery model for operation and establish safe operating period. The wattmeter no longer estimate or guess, but you measure and know!

Using the device can simultaneously measure and monitor the following variables:

  • Instantaneous current (A) - measures the instantaneous load current drawn from the source. It enables you to monitor the load of the battery pack, compare current consumption of the same electric motor with different propellers or with different gear ratios. Simultaneously displayed the maximum measured value.
  • Performance / power (W) - measures the instantaneous load power (electric motor). At the same time displayed the maximum measured value.
  • Source voltage (V) - measures the instantaneous voltage power supply (eg. Flight battery).
  • The flow-through electric charge (mAh) - allows you to measure battery capacity, remaining capacity, monitor the discharge of the battery during normal operation model etc. connects between the drive battery and an electronic speed controller, the receiver battery and receiver - generally between the battery and the load, between power supply and charger etc ..
  • Energy (Wh) - gives the ability to do work. It is a useful parameter eg. For evaluating the quality of the batteries: vybíjíte if two batteries of the same nominal capacity in the same stream under the same conditions, higher energy (in watt hours) recognizes the one that has less internal resistance. I.e. an accumulator having the capacity to give larger discharge current and less loss manifesting its heating.

Power meter is connected to the network and is powered from a measured resource; due to the negligible internal resistance (0,001 ohms) and low current consumption for its own operation does not affect the function of the measured system.

4th Servotester

Servotester PPM is the source of control pulses for servos that can (in the range of pulse widths from 750 to 2150 microseconds), manually adjust the knob or let defecting automatically. Accordingly, it will move the connected servo; as well servotesterem can also control the electronic speed regulator or other devices controlled by a standard servo signal. To use servotesteru need for power-Meter also connect an external source (eg. 2-8S LiPo battery).

5. An optical tachometer

For measuring the speed propellers and rotors (up to 60,000 rpm) is well-Meter is equipped with a built-in optical sensor. Tachometer measured at normal daylight for measurement is placed in a distance of 10-20 cm from the propeller. You can measure the propeller 1-5 sheets. To use the tachometer is needed to power the i-Meter connect an external source (eg. 2-8S LiPo battery).

6. Contact Thermometer

S i-Meter is supplied temperature sensor capable of measuring temperatures in the range 0-150 ° C. To use the thermometer is needed to power the i-Meter connect an external source (eg. 2-8S LiPo battery).

7th calculator static thrust

Static thrust calculator helps you estimate the thrust of aircraft. Suppose you have a model airplane and going to the first flight. Do you know the dimensions of the propeller with the tachometer can measure static speed at full throttle on the ground. Now the known numbers can be entered into the calculator move. Because you can with a great degree of reliability to determine what thrust available to you, you advance idea of \u200b\u200bthe ratio of thrust / weight of your model aircraft. You will know more about your model, you can better predict its behavior in the air with regard to the performance of its propulsion system. This will make the first flight less adventurous and more secure; After all, you might be busy in dealing with other flight characteristics. You should also be able to better estimate the takeoff. In the case of 3D models you will be able to assess whether the model will be really able to hang. The calculator can show you how it will change, thrust using propellers of different diameters. To use the calculator is needed to power the i-Meter connect an external source (eg. 2-8S LiPo battery).
