Signal Analyzer

PDF Data Sheet

*For full Technical Specifications, please refer to PDF Data Sheet.

Functions:

Measures voltage between DC system and ground ranging from 0 to 300V.

Measures grounding resistance up to 999KΩ for both busbars and each branch circuit

It detects and measures AC voltage which interrupts in DC system. Detection range is from 0 to 288V.

It performs the function as accurate current meter with resolution up to 0.01mA.

Arrow indication effectively helps users trace the signal and pinpoint the ground fault.

Waveform display for tested circuit, indicating insulation status and current changes in tested circuit, it help users fast and effectively locate the point with grounding fault.

It tests and displays distributed capacitance in the system in real time.

Fast signal positioning for the point of ground fault for both negative and positive busbars with the help of waveform and signal direction.

Signal analyzer has different working modes like amplitude adjustment, frequency adjustment and waveform view which are very helpful for signal fault location in high resistance grounding.

The analyzing function of signal frequency spectrum effectively helps extract the testing signal amplitude which makes measurement more accurate.

Key Features:

Safe to use: It could quickly pinpoint the ground fault without injecting signal to DC system. There is no interruption to DC system itself during signal fault location with its built-in model for current and voltage limitation.

High reliable designing It adopts main system of 16-bit micro-processor. Hardware designing strictly follows EMC standard to ensure reliability of itself and its tested systems.

Precise measurement It adopts high accurate current clamp for signal tracing and precise ADC for voltage sampling. This ensures the accurate measurement of voltage and resistance.

User-friendly interface It has LCD display with vivid information indicating grounding status, waveform, insulation leveling, insulation resistance, leakage current, and direction of ground fault and so on. This user-friendly interface makes it easy and effective to use onsite.

Intelligent measurement function

Signal analyzer can automatically identify system voltage leveling.

When insulation resistance has any change, signal analyzer could quickly indicate the changes.

Distance will not affect the signal detection once the signal analyzer and detector are synchronized.

During fault location, current clamp could either clamp on single cable or multiple cables for faster and more effective signal tracing.

Signal detector will indicate the direction of ground fault on screen once it detects any insulation problem.

Complete measurement and trouble-shooting function

Signal detector and analyzer have wireless communication. Complete

measurement and info displaying function could handle different types

of insulation problem in DC system.

Signal analyzer has different working modes like amplitude adjustment, frequency adjustment and waveform view which are suitable for different complicated applications.
