CEM DT-9330 is an advanced two-pole voltage tester
It is not only for quickly checking the presence of voltage and approximate values in low-voltage electrical installations. LED indicators to display voltage levels AC/DC 12V-1000V. covering household, commercial scenarios.
this Tool includes more feasures like
-- Polarity detection
-- Continuity Testing: Used to check whether fuses, switches, or wires are intact
-- Phase Sequence and Single-Pole Testing: In three-phase systems, used to determine phase rotation direction; single-pole mode can quickly identify live wires
-- built-in 30mA RCD (residual current device) test function, allowing one-click verification of whether the leakage protector trips properly.
-- switchable load function, which can suppress stray voltage (phantom voltage) in the circuit, preventing misjudgment of zero voltage as live voltage.
According to standards such as IEC/EN 61243-3, this two-pole voltage tester can be permitted to check circuit in building electrical.
Safety:
IEC61010-1 CAT III 1000V / CATIV 600V
CE, UL, CSA, and TÜV listed for maximum safety and global compliance
Applications:
-- Building Electrical: Verifying sockets, switches, and distribution panels in homes and offices.
-- Industrial Maintenance
-- vehicle repair and maintenance
