6. Press ENTER to view the voltages for all cells in the pack. A
fl ashing “
■” symbol next to any cell voltage indicates that cell is
being balanced. Press ENTER to return to the previous screen.
Press ESC to manually stop the balancing function. Once balancing
is complete the meter will automatically move to power down mode
in 15 seconds. Press ENTER to revive the meter which will revert to
the previous screen.
If balancing is not in progress, pressing ESC will return to the CELL
BALANCER screen.

This mode is for measuring total load current, battery voltage, used
battery capacity, and electric power. This function can be used to
measure data between a battery and electronic speed control, charger
and a battery, or discharger and battery. PowerMatch can measure and
store average, minimum, and maximum values in this mode.
Note that heating may occur within PowerMatch when high
currents are passed through the meter continuously for more
than 2 minutes. This may cause the accuracy of the readings
on the display to decrease. It’s therefore not recommended to
allow continuous current of over 50A to pass through the meter
continuously for more than 2 minutes. Once a load current has
passed continuously through the meter for 3 minutes all data on
the LCD will automatically begin to fl ash. This simply notes that
meter accuracy may be reduced as a result of internal heating if
higher currents are being passed through the meter. The fl ashing
will stop when the battery is disconnected from the meter, or if the
function is stopped manually by pressing ESC.
MEASURING DATA FROM BATTERY TO ESC:
1. Connect the 2S-7S lithium
battery to the BATTERY input as
shown in Fig. 5. Do NOT connect
the lithium battery’s balancing
lead to the meter.
2. The POWER CHECKER
screen should appear automati-
cally. If not, press MODE until
this screen appears.
