6000 COUNT DIGITAL AUTOMOTIVE
MULTIMETER WITH SQUARE WAVE GENERATOR
INSTRUCTION MANUAL
This instrument is a compact 6000 count digital automotive engine analyser
multimeter, with a unique square wave generator. This tool is designed for the
professional mechanic.
Key functions include AC / DC Voltage, AC / DC Current, Resistance,
Capacitance, Frequency, Duty cycle, Temperature, Diode / Continuity testing,
Tachometer, Dwell, ms-PULSE, Analog Frequency / Duty / Voltage / Resistance
Signal Output.
The square wave can be generated from 1 – 12V DC | 10% - 90% duty cycle |
20Hz – 3,000Hz. This output is easily adjusted from the buttons on the face of
the tool, and using the dual banana jacks marked “output”.
Safety Warnings
DANGER
Engines produce carbon monoxide which is odorless, causes slower reaction
time, and can lead to serious injury. When the engine is operating keep
service areas WELL VENTILATED or attach the vehicle exhaust system to the
shop exhaust removal system.
Set the parking brake and block the wheels before testing or repairing any
vehicle. It is especially important to block the wheels on front-wheel drive
vehicles. The parking brake does not hold the drive wheels.
Wear an eye shield when testing or repairing vehicles. Exceeding the limits of
this meter is dangerous and can expose you to serious or possibly fatal injury.
Read this manual carefully before use and be careful to understand the specific
safety limits of this meter.
