Multi-Functional Clamp Leakage Current Meter for Accurate AC/DC Measurement

The ETCR6640, ETCR6670, and ETCR6680 leakage current clamp meters suit electrical testing jobs that involve checking AC leakage current, assessing earth leakage, or examining current harmonics. Choose an option by matching its listed AC current range and clamp opening to the conductors you need to measure.

Compare the AC measuring ranges and resolution in the table when selecting a model. It does not establish the DC measurement limits. Check the manual for DC specifications before choosing this instrument for a DC leakage testing job.

Choose the Configuration for Your Measurement

• AC current range: Match the option to your measurement needs: ETCR6640 lists AC 0.00mA–300A, ETCR6670 lists AC 0.00mA–1200A, and ETCR6680 lists AC 0.00mA–2000A.
• Clamp opening: Check conductor fit before ordering. Listed CT sizes are Φ40mm for ETCR6640, Φ70mm for ETCR6670, and 80mmX80mm for ETCR6680.
• Low-current readings: The table lists AC 0.01mA resolution for each option. Check the specifications or manual for accuracy at the leakage current level you need to measure; resolution alone does not establish accuracy.
• Filter setting: The listed frequency bands are 40Hz–70Hz with the filter open and 40Hz–1kHz with the filter close. Check which setting suits your measurement before use.
• Power and display: The meter uses a rechargeable lithium battery and includes an LCD backlight, spotlight, and data hold. A charge adaptor is included.

Questions Before Ordering

Does the specification table confirm a DC leakage current range?

No. The ranges and resolution in this page's specifications cover AC measurements. Check the manual for DC range and accuracy before ordering for DC measurements.

Can this leakage current meter perform harmonic testing?

The specifications list harmonic analysis and distortion rate measurement above 10mA. Check the manual if harmonic testing is needed at or below that current level.

Can I view and save readings on a phone?

Bluetooth communication lets you test or view results on a mobile device after installing the APP. The specifications list storage of 2000 groups via the APP.
