1000A AC Leakage Current Tester

The CEM DT-9812 measures AC leakage current up to 1000A using 68mm transformer jaws that can clamp around three or four conductors simultaneously. It is designed for electricians and maintenance technicians who need to verify insulation integrity on three-phase systems. True RMS sensing ensures accurate readings on distorted waveforms. A frequency filter switch removes harmonic interference from the measurement.

Thermals Noise and Power Draw

The instrument operates on user-supplied batteries, which are not included in the package due to shipping restrictions. No thermal, acoustic or power-consumption figures are provided by the manufacturer. The large LCD features a backlight for visibility in dim environments. Data hold and peak hold functions allow the operator to freeze readings without keeping the jaws closed.

Upgrades and Replacements

This tester replaces clamp meters that lack the jaw size to encircle multi-conductor bundles or the filtering needed for noisy electrical panels. The IEC 61010-1 CAT III 600V rating suits industrial and commercial switchgear work. It is not suited for users who require DC current measurement, integrated data logging or wireless connectivity. Buyers needing higher current ranges or smaller jaw profiles should consider other models.

Questions about this item

How do I install the CEM DT-9812 and what step is often missed?

Open the 68mm jaws, clamp around all three or four phase conductors together for leakage current measurement, select the frequency filter to remove harmonics, and insert the required batteries which are not included in the package.

What maintenance or replacement will the CEM DT-9812 need later?

The tester requires periodic battery replacement since none are supplied, and the manufacturer highlights a three-year parts and one-year labor coverage period for any service needs.

What limit appears first during sustained use of the CEM DT-9812?

The IEC61010-1 CAT.III 600V safety rating defines the maximum circuit voltage, while the 1000A AC measurement range caps the current that can be displayed continuously.
