This manual introduces the basic functions of the CP7665 multimeter and automotive testing methods.
This manual provides operating instructions for the Actron CP7665 automotive tester. It details basic multimeter functions such as measuring DC/AC voltage, resistance, current, and testing diodes and batteries. The device features a rotary switch for function selection and includes hold, display light, and automatic polarity sensing capabilities.
The guide also covers specific automotive testing procedures using the CP7665. These include general testing of fuses, switches, solenoids, and relays, as well as starting/charging system tests like no-load battery tests, cranking voltage/load tests, charging system voltage tests, and ignition/fuel system diagnostics.
| DC Volts Range | 0 to 500V |
|---|---|
| Resistance Range | 0.1Ω to 20MΩ |
| AC Volts Range | 0 to 500V |
| DC Amps Range | 0 to 10A |
The manual states that a 9 Volt battery must be installed before using the digital multimeter.
The multimeter should be set in the lowest possible range without overranging; if '1' or '- 1' appears, increase the range.
