## Overview

The ECV520i by Tektino is a professional-grade electronic control valve tester designed for variable displacement AC compressors. It measures PWM signals, outputs adjustable PWM duty cycles, and tests ECV solenoid resistance to ensure accurate diagnostics. With built-in reverse polarity protection and a compact, durable design, it significantly reduces repair time and prevents costly misdiagnoses.

## Description

For A/C with variable displacement compressor, when the compressor work status is found abnormal, it is necessary to accurately diagnose whether the fault is the compressor itself, the ECV solenoid or the electronic control system. ECV520i can test the control PWM signal issued by the electronic control system, and can also bypass the electronic control system to directly drive the compressor ECV valve, as well as it can test the resistance of the ECV solenoid. Eventually the ECV520i can accurately determine the fault is the electronic control system, the compressor or the ECV solenoidSpecifications:Power supply: Battery power, 12VDCPower cable length: 2.5MTest cable length: 2.1MConnectors: specific connector 12 pairs (male and female), universal connectors 3 pairs (male and female).Duty cycle range the tester issues: 18%-84%, PWM signals. The bigger the duty cycle is issued, the larger displacement the compressor achieves.Note: Protection against reverse battery connection.

## Features

- Test function: Measure the PWM signal issued from control system, to determine the control system work status
- Output function: Issue PWM signals of different duty cycles to check if the compressor works properly, thus to determine the compressor work status. In this function the duty cycle of PWM is changed manually by pressing the buttons
- Resistance function: Measure the resistance of ECV solenoid. The normal resistance range of ECV solenoid is 10-14Ω，out of this range can be considered ECV solenoid failure
- ECV520i can largely reduce repair time and cost, eliminate misdiagnosis, and avoid the costly repeated repairing. The tester also has electric protection when battery cable is reversely connected by mistake
