Multifunctional Monitor & Logger PowerLog 6S
 Motor KV Meter
KV as we use it refers to the RPM constant of a motor - it is the number of revolutions per minute that the
motor will turn when 1V (one Volt) is applied with no load attached to the motor.
Mode0: It works at the 2-wire mode, suitable for the KV
measurement of brushless motor.
Mode1: It works at the 3-wire mode, suitable for the KV
measurement of both brushed and brushless motors.
Regarding the specific operations, please refer to MAIN MENU -> Motor KV Meter P17
Wire Connection Methods of Mode0 and Mode1 as the picture below:
Notes: 1. When measuring KV on the Mode0, the throttle settings of ESC needs to be set at the Max. value.
2. If the tested voltage is lower than 4.5V, PowerLog needs auxiliary power supply.

Data Logging
When in Monitor status, press <▼> button for 3 seconds, after it shows ―Start logging…―, the ―____‖ will be
shown alternatively at the upper right corner of the LCD screen. In this status, the system will transmit the
data to USB port every X seconds( this interval time X can be set by user himself, details you can see Record
Interval Time Settings in P19), and save these data to the current Log file（See Log File Management in
P15. If 【Logs OFF】, the system will not log file．）
Press <▼> for 3 seconds again, the screen will show ―Stop logging! ― and then exit.

Alarm Remind
If PowerLog detect the alarm events (See Alarm Parameters Settings in P13), it will remind as below:
1. The buzzer beeps every 4 seconds (See Beep Tone Settings in P17,【Alarm Tone】is selected ).
2. The corresponding value and alarm remind show alternatively.
Alarm Remind Information: ―LOW‖ — Lower MIN. limit alarm ―OVER‖ — Over MAX. limit alarm
―DIFF‖ — Difference alarm ―T_OVER‖ — Time over alarm
3. ALM port will output the presetting signal.
ALM port signal information:
ALM output port signal is open collector signal, as showed below.
Please pay attention to the port voltage and current limit when you use（<50V,<500mA）
The following are ALM Output typical application.
