MS121
Tester for diagnostics of electromagnetic valves and clutches of vehicle air conditioner compressors
Tester MS121 is a compact device for testing both electromagnetic clutches and control valves of automotive climate systems.
Manufacturer:
MSG Equipment
Overview
Tester MS121 is used to perform quick and easy check of the following parameters of electromagnetic clutch and control valve:
- presence of a diode;
- current consumption;
- short circuit (cs);
- circuit break (cb);
- rate of valve opening.
Both clutch and valve can be tested either on the compressor removed from a car (at a repair shop) or directly on a car.
Features:
- Simplicity and ease-of-use.
- Automatic polarity selection for connection of the tested unit.
- Simultaneous testing of a clutch and a valve.
- Possibility of a compressor electromagnetic valve control.
- Possibility to test without removing from a car.
