Three-Channel Leakage Monitoring
The ETCR8300-040A records up to three AC leakage or load currents simultaneously. It is built for electricians and power inspectors who need continuous on-site data rather than a single spot reading. The host shows all three channels on one LCD with selectable Chinese or English menus.
Clamp Integration and Storage
Each 35mm×40mm clamp opens to fit around conductors in 380/220 V systems, and one to three clamps can be connected depending on the job. The recorder stores 200000 data groups internally, and the memory survives power loss or battery changes. Software and a communication cable transfer the logs for later analysis.
Sustained Accuracy Under Load
Accuracy holds at ±1.5%±5dgt across the full 0.00 mA to 500 A range during long monitoring sessions. The clamp design maintains consistent coupling without overheating, so intermittent insulation faults are captured over hours or days rather than missed in a brief test.

Questions about this item
How many readings can the recorder store before it overwrites old data?
The internal memory holds up to 200000 groups of measurements and retains them even if power is lost or the battery is replaced.
Does the clamp generate noticeable heat or noise during continuous monitoring?
The clamp is a passive sensor with no moving parts or active cooling, so it runs silently and produces no measurable heat during all-day use.
What power-system voltage must the installation already have for this tool to be used safely?
The recorder is designed for 380/220 V AC systems, so the site must provide a compatible three-phase or single-phase supply within that range.
