By attaching an Amp Clamp or Lab Scope, you can monitor the current or amperage readings. It allows a technician to judge the health of the DC electric motor to identify if a motor is drawing more current than specified, or if the current load is inconsistent during operation. Control relay circuit independent of “key-on/key-off” systems Run all automotive, 12V DC motors with a push of a switch Simplifies fuel injection testing Use in conjunction with clamp-on Amp Probes and Lab Scopes Operating range: Up to 20 amp continuous, 30 amp surge (12V) Covers most makes and models Show more
