HZCR-5000 Smart Multi-function Power Quality Analyser
A three-phase power quality analyzer is a device used to analyze and monitor power quality in three-phase power systems. It measures parameters such as voltage, current, power factor, harmonics, and voltage dips. The instrument typically consists of a display, data storage, measurement sensors, and control devices.

The direction of the end of the current clamp with the same name is as follows:
The current clamp is marked with an arrow, and the direction of the arrow is the input side, which is the input end of the same direction as the current, that is, the end with the same name.
The S-008 current clamp is marked with an arrow, and the direction of the arrow is the input side, which is the same-direction input end of the current, that is, the end with the same name.
S-070, S-105, and S150 current clamps are marked with red arrows, and the direction of the arrow is the input side, which is the input end of the same direction as the current, that is, the end with the same name.
The S-200JF flexible coil current sensor is marked with a black arrow, and the direction of the arrow is the input side, which is the input end of the same direction as the current, that is, the end with the same name.

How do I select the right current sensor and verify correct connection polarity?
Sensor selection: Match the expected maximum current to the sensor range - always use the smallest sensor whose range exceeds the maximum current. Using a 1,000A clamp on a 5A circuit gives poor resolution; using a 10A clamp on a 50A circuit will overrange the input.
Polarity identification (critical - reversed polarity causes incorrect power sign and phase angle):
10A clamp: the side with the red dot is the current non-inverting input (→ toward the load)
100A / 1,000A clamp: the side without screws is the current non-inverting input (→ toward the load)
6,000A Rogowski coil: the arrow icon (lock logo side) marks the current direction input
Quick polarity check: after connecting, display the phasor diagram. In a normal inductive load with correct connections, the current vector for each phase should lag its corresponding voltage vector by a small angle (0°–90°). If a current vector leads voltage or points in the opposite direction from the other phases, that CT is reversed.
