English Version Inverter Refrigerator Compressor Detector Tester Refrigerator Repair Tool Pulse Solenoid Valve Detection

  Four in One Inverter Refrigerator Detector：Small size，Light weight，Complete function，be easy to carry about。It can effectively improve maintenance efficiency.，Reduce misjudgement。Detector can： Direct Start Frequency Converter Refrigerator Compressor（Frequency Converter Contractor for Refrigerator）Detector can directly drive refrigerator frequency converter board detector to directly judge the quality of bistable pulse valve，Regulating the Operating Frequency of Compressor，Observing the operating state of each frequency.

  purpose：Frequency Converter Board Detection：Frequency Converter Board Detection; Connect the detection line of detector frequency converter board to the communication interface of refrigerator frequency converter board（Make sure that the frequency converter board is available before testing.220vPower supply）Turn on the power switch of the detector， After correctly matching the parameters of the detector with the frequency converter，Compressor can start directly。If the compressor starts，It can judge whether the compressor and frequency converter are normal or not.。If the compressor does not start，inspect Compressor with Compressor Testing Function（Be careful：After starting compressor，Test should wait3-5Minute，Testing will be performed after system pressure balance.。）

  Frequency Conversion Compressor Test;Frequency Conversion Compressor Test; Connect the detection line of detector compressor to refrigerator compressor，Turn on the power switch of the detector。 Detector will automatically match compressor parameters。 After matching，Compressor can start directly。 If the compressor does not start，Compression failure can be judged.。 （Note that once the compressor starts，Wait before testing3-5Minute system pressure balancing。）Pulse solenoid valve test：Connect the solenoid valve detection line of the detector to the solenoid valve interface，Press red Detecting solenoid valve and green key respectively，Judging whether solenoid valve is reversed twice。 （Attention detector outputDC220Pulse voltage，Do not touch when using.BadDetector has short circuit protection function，Output Short Circuit Will Not Damage Detector

Examples of Application of Detector1

A Haier Refrigerator User Says No Refrigeration，It was found that the frequency converter compressor did not work by the door-to-door inspection of the repairman.，Determining the Fault to be Frequency Converter Bad with Detector。Haier Refrigerator Leaks More，Teacher also uses the compressor detection function to start the compressor directly.，Let it work1Minute，No Temperature Rise in Hand-felt High Pressure Tube。Judging Pipeline Leakage，After communicating with users, pull back to the store to change pipes and frequency converters。Perfect Repair，Avoid the embarrassment of compressor working but not refrigerating after changing frequency converter board。Win User Trust，Improving Maintenance Efficiency。 

 Examples of Application of Detector2

One user said that the refrigerator at home was not refrigerated，Maintenance master door-to-door inspection found that the frequency converter compressor does not work，Diagnosis of Compressor Fault by Detector，Refrigerators often leak，To ensure that nothing is wrong，Open the process port without refrigerant ejection after user's consent。Tell the user to pull back to the store to replace the compressor and replace the pipeline，Pull back to repair with user's consent。

 Examples of Application of Detector3

One user said that the refrigeration room of the refrigerator at home was not refrigerated，It was found that the solenoid valve was not reversed by the master's door-to-door inspection.，Fault Diagnosis of Electromagnetic Valve by Detector，Replacement of solenoid valves after quotation to users。Troubleshooting

Examples of Application of Detector4

A Haier Refrigerator User Says No Refrigeration，It was found that the frequency converter compressor did not work by the door-to-door inspection of the repairman.，Determining the Fault to be Frequency Converter Bad with Detector。Haier Refrigerator Leaks More，Teacher also uses the compressor detection function to start the compressor directly.，Let it work1Minute，Hand-felt high-pressure pipe burning。Judging that there is a normal pipeline，After quoting the price to the user。Rapid Repair，Win User Trust，Improving Maintenance Efficiency。

Examples of Application of Detector5

A refrigerator user says it's not refrigerated，It was found that the frequency converter compressor did not work by the door-to-door inspection of the repairman.，It is good to judge the frequency conversion board and compressor by the detector.。Then use the multimeter to measure the motherboard discovery12VPower Supply Talents9.5Volt，Observation of slight bulging of power filter capacitor，Refrigerator works normally after replacement。Perfect Repair，Win User Trust，Improving Maintenance Efficiency。Avoid detours。
