Technical indicators#

  • Maximum measuring range: voltage maximum 24V, current maximum 5A

  • Use 0.4% ± 20ppm precision reference chip, reserve 0.1% reference position, 0.1% precision resistor, 12 bit ADC design. The nominal accuracy is 1% (typical value is 0.5), and the user can further calibrate the accuracy to reach 0.1%。

  • Automatic measurement range: the current echo gears are 500 μA, 50mA and 5A respectively, which are automatically switched according to the current output current.

  • Gear switching speed: CC table adopts multi-channel synchronous sampling, no shift delay.

  • Voltage drop switching speed: CC meter uses 2/3 channel sampling resistor, and the maximum delay when the sampling resistor is short-circuited is 100uS

  • Current measurement accuracy: resolution 0.15 μA in 500μA gear and 100 μA in 50mA gear (table below)

  • Fixed multi-channel 10KHz sampling rate, USB high-speed data transfer

  • Can cooperate with PC client to view and analyze current waveform, can also use command line version to capture serial port data (such as strawberry pie) on any device (win/linux/mac), use pc client to import and view
