This USB meter could only test the
real-time voltage, current, electric
power, and accumulated charging/
USB TE STER

The charge or discharge current is
determined by both the USB device that
is being charged and the charging head,
instead of reaching the same charging
current that the charging head does
When testing the capacitance, this unit
could only calculate the sum output
volume of the two USB ports, excluding
the conversion efficien-cy of the
front-end and back-end equipment
It is normal that the charging current
would decrease gradually along with
longer charging time
This USB multimeter operates through
a USB extension cable for in-putting
and other two ports for outputting that
are “Output Ⅰ and “Output Ⅱ” ”
The “Output Ⅰ port is suitable for all
the original chargers including Apple
Series, and could be used for both
charging and data transfer-ring,
however the charging current is
determined by both the charg-ing
identification lines inside the charger's
USB port and the compa-tibility of the
USB device that is being charged.
(When the “Output Ⅰ is charging with
the Qualcomm QC 2.0, the “Output Ⅱ
”
”
”
port mustn't accept any other USB
devices)
Functions
The “Output Ⅱ port is equipped with
an intelligent identification IC that can
match the most appropriate and safest
large current to charge quickly, which
mainly for the non-original chargers
besides original chargers.
(It supports: BC 1.2, YT/D1591-2009,
and the non-BC 1.2 USB standards of
which include the iPhone, iPad from
Apple and the Samsung Galaxy series)

Button Usage
Pressing the button for switching
among seven different displaying
modes
Parameters
Input Voltage/ Voltage Testing:
3.20-15.0V ( the decimal point shifts
automatically)
Sensitivity (or Resolution):
0.01V (＜10V ), 0.1V (≥ 10V )
Current Testing:
0.00-3.00A (Max to 10A, but can not
operate at 10A for long time)
Sensitivity (or Resolution): 0.01A
Capacitance Testing:
0-99999mA/H ( namely 99.999A/H)
Electric Power Testing:
0.00-9.99-99.9W (the decimal point
shifts au-tomatically )
Overvoltage/Undervoltage Alarming:
1.When the voltage ≥ 5.6V, the decimal
point of voltage is flashing very quickly
2.When the voltage ≤ 4.4V, the decimal
point of voltage is flashing very slowly
Overcurrent Alarming:
when the current ≥ 3A, the decimal
point of current is flashing very quickly
Short Circuit Alarming: when the short
circuit occurs, the decimal point of
current is flashing very quickly
Capacitance Checking
Accumulated Capacitance: there are
numerous accumulation of charging
capacitance when continuously
powering on
When powering on without access
to any USB device, it displays the
accumulated capacitance for the last
time (PS: the unit has the func-tion of
Non-volatile Memory)
When powering on with the capacitance
cleared, it displays the nu-merous
accumulated capacitance of charging
or discharging by the present
Long pressing the button by “flashing
twice” to clear the accumulated
capacitance
