Important information for our Power Analyzer PRO users
Using the Power Analyzer PRO to control an ESC and
operate a motor an error in the measured current can
result due to an inadvertent ground connection on the
Pro circuit board. This condition will produce a measured
current reading that is lower then actual. We recommend
disconnecting the ground connection (brown or black wire)
from the three pin connector on your ESC to restore the
measured current to its correct value. Removing the ground
connection is not required on more recent Power Analyzer
PROs as this inadvertent ground connection has been
corrected so no action is required.
If you use an OptoIsolator (Opto) to connect the Power
Analyzer PRO to your ESC then it is not necessary to
disconnect the ground wire. In fact, you have to have
the ground wire connected for the Opto to work.
To determine if your Power Analyzer PRO requires any
action, connect it to your computer and run PowerPROview.
In the lower left-hand corner, you will see a readout
similar to the one shown below. If your serial number
starts with the letters “MR” (S/N MRxxxxxx), as is shown,
follow the instructions above to ensure the most accurate
operation. If your serial number starts with the letters “MS”
(S/N MSxxxxxx) instead, the hardware has already been revised
and it is unnecessary to remove the brown or black wire from
your ESC connector.
