The PowerTool software and the Power Monitor hardware provide a robust power measurement solution for mobile devices. The PowerTool so ftware and the Power Monitor Hardware can analyze the power On any device that uses up to a 3-cell Lithium-Ion Battery, supplying up to 13.5V and 6 Amps. Electrical engineers and software developers can utilize the PowerTool software and the Power Monitor hardware to optimize the design and analyze the performance of their mobile devices.
Figure 1 Graphical user interface (GUI) for the PowerTool software
The Power Monitor can measure data on three channels: Main, USB, and Auxiliary. The Main channel is what most users will use for their measurements. A USB channel is provided as is an AUX channel . The GUI details are described below for the Main channel, but largely apply to all sampling sources. Cases where they differ are called out in the appropriate sections on USB or AUX measurements.

Prior to installing the latest version, uninstall any previous version of the Power Monitor Software from the Control Panel.
Create a new temporary folder on the development workstation under the root directory
Copy PowerTool.zip to the Development workstation.
Extract the contents of PowerTool 5.X.X.X.zip to the temporary folder.
Run PowerTool Install.exe
Follow the on screen prompts to install the PowerTool Software.
After the PowerTool application has been installed and this is the first time the workstation
will be running the PowerTool application you will need to install two drivers, the Power
Monitor driver and the Firmware driver. Instructions are as follows:
1.Power on Power Monitor in normal mode ?Green led should be on.
2.Under Device Manager, find Mobile Device Power Monitor ?will have a yellow exclamation mark.
3.Right click and select Update Driver Software?
4.Select Browse my computer for driver software
5.Browse to C:\Program Files (x86)\Monsoon Solutions Inc\PowerMonitor\Drivers\PC and click on Next.
6.Click on Close once the driver has finished installing.
7.Under Device Manager ?Universal Serial Bus devices, ensure that the Mobile Device Power Monitor has enumerated properly.
1. Power on the Power Monitor in Output Enable mode by depressing the Output Enable button and the Power button simultaneously ?Amber led should be on.
2.Under Device Manager find the Unknown device and right click, select Update Driver Software?
3. Select Browse my computer for driver software
4. Browse to C:\Program Files (x86)\Monsoon Solutions Inc\PowerMonitor\Drivers\Firmware and click on Next
5. Click on Close once the drive has finished installing.
6. Under Device Manager ?Custom USB Devices verify that the Microchip Custom USB Device has enumerated properly.
The Power Monitor is shipped with the latest firmware and in most cases will not be required to be updated. If for any reason the firmware does need to be updated use the following instructions.
Power on the Power Monitor in Output/Enable mode by pressing on the Output Enable button and Power button simultaneously. The amber light should be on.
Figure 3 Output Enable button
Start the PowerTool application, and select the Reflash option, which is enabled whenever a Power Monitor device in boot mode is detected.
Figure 4 PM Flash Select Option
Click on the Load button and browse to the PMFlash folder where the PowerTool application
was installed and select the PM_RevX_ProtXXVerXX_Boot.fwm file. (Note, X is a placeholder for the proper version information for a given fwm file, for example,PM_RevD_Prot18_Ver21.fwm). The Reflash utility is also compatible with the deprecated .hex file format used in previous firmware releases.
Click on the Write button
Wait until the Status shows ?Write complete?.
Click on the X in the upper right of the window to exit when you are done.
Power off and then power back on the Power Monitor so you now have a green light.

1.Ensure to read all instructions carefully before operation. Using the Power Monitor in A manner not specified by this manual may damage the equipment and impair protections designed for user safety.
2.Be sure that the power switch on the front of the Power Monitor hardware is not engaged. The hardware should not be powered-up.
3.The power switch should be in the outward position, not the inward position.
4.Connect the supplied 16 VDC / 7.5 Amp, power supply to the back of the Power Monitor and a wall power supply matching the unit抯 input requirements (100-240V, 47-63 Hz, 1.6A Maximum)
5.The power supply should be positioned so that it is within easy reach in the event that it needs to be disconnected for safety. Ensure this by placing the power brick on the same work surface as the Power Monitor with the AC input side facing the user. Ensure there are no obstructions in the work area that may impede you in the event of an emergency.
6.On a development workstation that is compliant with Full-Speed USB 2.0, connect a USB cable to the USB connector on the back of the Power Monitor hardware, and connect the other end of the USB cable to the development workstation. Do not connect to an external USB hub device.
Do not connect a third party power supply to the Power Monitor. The connector used does not have a standard pinout, and an improperly selected Power Supply may damage the device. If a replacement power supply is Required, contact Monsoon Solutions.

Refer to the Appendix on how to properly configure a device battery to connect to the Power Monitor.
Note Wear ANSI Z87.1 compliant safety goggles at all times while working with exposed battery terminals and wiring.
Connecting the Power Monitor to a device to collect current measurements can be complicated and dangerous. Be sure that the area where power measurements are being conducted is protected from fire danger, do not have flammable items
nearby. These measurements are at your own risk, and these procedures are not guaranteed to prevent damage or injury.
Note When attaching the power measuremenT hardware to a device with a lithium battery, there is always a risk of damaging the device, or causing the device to heat-up, Generate smoke, or catch fire. While this is unlikely, be extremely careful. It is recommended to work on a flame-resistant surface and have fire control equipment at the ready when performing the battery bypass and connecting the Power Monitor to the device under test. Immediately disconnect equipment that begins to exceed safe temperatures.
