DELTATECH A/C system tester DTE/ACT-2
Specification
The ACT-2 tester is used to verify the correct operation of the following types of air conditioning compressors:
– compressor with electromagnetic clutch – checking the condition of the electromagnetic clutch,
– clutchless drive compressor – checking the operation of the electromagnetic valve controlling the compressor's efficiency.
Note! The tester does not support electromagnetic valves with a built-in protective diode (valves used, among others, in Mercedes cars). Using the tester on this type of valve may damage the valve or the tester.
The tester can be used both on an air conditioning test stand and when checking the compressor in the car.
