• A/C Diagnostic Tool – Valtest 371

    The Supercool Valtest 371 A/C Diagnostic Tool is designed to diagnose failing A/C systems with electronically controlled compressors.

    Description The Valtest 371 performs a quick, easy-to-understand analysis of the compressors operation, the strength of the electronic control unit signal, and the functionality of the valve by determining whether there is a short-circuit or open-circuit and whether the failure is in the electronic control unit or the compressor. The Valtest 371 makes it possible to effectively diagnose the new generation of electronically controlled A/C compressors. **Includes Extra connection leads worth £55.00**

    SMG5 – Digital Megohm Meter

    Evaluate Compressor Insulation. Helps to Predict Compressor Failure. 1000VDC voltage source Measure up to 2000 megohm Backlit LCD The Fieldpiece Digital Megohm Meter, model SMG5, is a compact standalone meter designed for checking HVAC compressor insulation. The SMG5 provides a 1000V voltage source, monitors current, and displays the resistance between the test points. Maximum current output is <1mA. It can be used to determine the condition of insulation from winding to ground in a motor, compressor, or transformer. Includes a case, alligator clip lead tip and leads with removable tips. To test resistance, a DMM supplies low voltage (<1V) to the test points and is capable of delivering only a few milliamps. It’s not a high enough voltage to detect high resistance problems that might indicate moisture and other contaminants and it’s not enough current to measure lower values of resistance.
