Kyoritsu 4118A Digital PSC-Loop Tester Instruction Manual
This manual provides detailed instructions for operating the Kyoritsu 4118A digital PSC-loop tester, including safety precautions, instrument layout, test lead specifications, and measurement procedures for loop impedance and prospective short-circuit current. It also covers operating conditions, safety categories, and troubleshooting.
The tester is designed for single-phase AC systems (230V) and supports both phase-to-earth and OLD-TT system phase-to-neutral measurements. It features overload and overheat protection, manual and auto-test modes, and displays measurements in ohms and amperes with 3 1/2-digit resolution. This manual is written in Chinese.

How does the tester handle RCDs during testing?
For models 4118A without D-LOK circuitry, all RCDs (RCCB, ELCB) must be bypassed during testing, except on the loop-2000Ω range.
From: Kyoritsu 4118A Digital PSC-Loop Tester Instruction Manual
What is the D-LOK circuit?
The D-LOK circuit is an automatic device (RCD) lock that avoids the need to by-pass most RCD's during testing.
