2.Wiring method
Wiring method instructional video:
(1). Self-powered wiring method
If the voltage range of the battery being tested is between 10-120V during
normal operation, the self-powered wiring method can be used. First, switch
the power selection interface to "2W". Then, when wiring, connect the positive
pole of the battery to the "Vsns" port of the power supply interface using a wire
that doesn't have to be particularly thick, 13-16AWG wires are all acceptable.
Pay attention not to connect the positive and negative poles of the battery
incorrectly.
Connect the negative pole of the battery to the screw with the "BATT-" mark on
the sampler, and connect the negative pole of the charger and the negative
pole of the load to the screw with the "LOAD-" mark on the sampler. It is better
to use copper nose for wiring as it is more secure. During charging, the
direction of the current symbol is green and shows "charging", while the
remaining capacity value increases. During discharge, the direction of the
current symbol is light blue and shows "discharging", while the remaining
capacity value decreases.

(2). External power supply connection method
The voltage range for external power supply measurement is 0-120V. First,
turn the power supply selection interface switch to "3W", connect the positive
pole of the external power supply to the "VEXT" interface of the power supply,
and connect the negative pole of the external power supply to the "GND"
interface. Then, connect the positive pole of the battery to the measurement
module "Vsns" of the power supply. It is important to ensure that the positive
and negative poles of the external power supply are not connected incorrectly.
The negative pole of the battery is connected to the screw on the sampler
marked with the "BATT-" symbol, and the negative pole of the charger and the
negative pole of the load are connected to the screw on the sampler marked
