Solenoid Tester

The innovation Solenoid Diagnoser is the indispensable tool for repairing a faulty vehicle on-site!

Introduction

SD-1000 Solenoid Diagnoser is an innovation instrument to diagnose engine solenoids on-site of a faulty vehicle. With the help of the instrument, the faulty components on the engine can be found faster and so is the repairing time. The instrument can detect solenoid electrical faults as well as mechanical faults, such as stuckvalve.The instrument may be used also for checking the condition of a solenoid in a repairing shop. A rich database contents most of solenoids on commercial vehicles is pre-installed in the instrument. The instrument is an indispensable tool to diagnose solenoid faults for every technician in the vehicle repairing industry.

Features

• Hand-held portable design
• User friendly, easy to operate without any special training
• Check solenoids on-site of a faulty vehicle
• No impact on the solenoid being tested
• Factory pre-installed database with various solenoids by many manufacturers
• User is able to add new solenoid data into the instrument to expand its application
• Powered by a 9V battery. Low power consumption with low battery charge indication
• Accessories including harnesses, battery and user’s manual.

Measurement principle

• Measure solenoid coil both resistance "R" and inductance "L" to determine the solenoid condition
• Using percentage to represent the measured values of solenoid resistance and inductance 
  • The percentage is measurement over the reference data in build-in database 
  • If the measured value equals to reference, 100% on screen
  • If the measured value is 10 % less than reference, 90% on screen
  • If the measured value is 10 % larger than reference, 110% on screen
• Determine solenoid faults
  • If measured resistance  is significately larger than reference, a open circuit symbol " --| |--" on screen
  •  If measured resistance is near zero, a short circuit symbol "|----|" on screen
  • if measured inductance is 20% higher than reference, a valve stuck symbol "-|||-“ on screen 

Factory-Installed Database

• Common rail diesel engine, solenoids on injectors and high-pressure pumps. The manufactures are
  • Bosch,Delphi,Denso,Siemens
• EUI/EUP diesel engines. The manufactures are
  • Bosch,Delphi,Cummins,CAT,DDC,Mercedes Benz, Volvo, Scania, Iveco
• HEUI diesel engines. The manufactures are
  • CAT,Navistar
• Solenoids on gasoline engines

Operation

•  Diagnose a solenoid
  • Press ”MODE” to set to ‘TEST’ mode
  • Select the target solenoid data from database
  • Press ”START’ to test the solenoid, the LCD displays
  • Based on the test results, the user is able to determine the condition of the solenoid, normal or faulty.
•  Add a new solenoid data to database
  • Connect to the solenoid in good working condition
  • Press ”MODE” to set to ‘TEST’ mode
  • Set the name of the new solenoid
  • Press ”START’ to test the solenoid
  • Press ”SAVE” to save the test results into the database
  • Connect to the solenoid again
  • Select the newly saved data from database
  • Press ”MODE” to set to ‘TEST’ mode
  • Press ”START’ to test the solenoid
  • If the test results on the LCD screen shows the values of “R” and “L” are within 100±10%, then the newly added data is valid. Otherwise re-do the new solenoid calibration.
