Brand Kewtech Corporation

The Kyoritsu 4118A a digital loop impedance tester, capable of measuring prospective short current (PSC). Designed to comply with an IP54 rating, the 4118A is comprised of a custom microprocessor to achieve high accuracy and reliability.

The Model 4118A has a dedicated cover to protect against an impact from the outside and prevent the operation part, the LCD and the connector socket from becoming dirty. The cover can be detached and put on the back side of the main body during measurement.

FEATURES

25A current 20Ω range gives great accuracy 0.01Ω loop readings.
15mA 2000Ω range will not trip 30mA RCDs or greater (1Ω resolution).
3 LEDs for checking correct wiring status.
Direct reading of Prospective Short Circuit Current (PSC).
Safe voltage measurement function.
Large custom digital display readout on all models.
Automatic lock-out if test resister overheats.
Large custom digital display readout.
Visual indication of reversed phase and neutral wiring at socket.
