The CPL2000A, CPL2000HA and CPL4000A are low-frequency AC/DC current probes with a built-in 4½-digit clamp-meter display. They measure up to 4000 A RMS with a BNC output for oscilloscopes, while the LCD shows the true RMS value (DC–400 Hz) directly.
Battery and USB dual power, two switchable ranges, auto-zero and over-range alarm make them convenient for high-current power, inverter and motor-drive testing.
