The Blue-Point MT596A, a professional-grade digital multimeter (DMM) marketed by Snap-on, is a staple tool for automotive technicians due to its ruggedness and specialized testing capabilities. This model is specifically engineered for automotive diagnostics, featuring functions like frequency, duty cycle, and RPM measurement. Key Specifications and Features
The MT596A is designed to withstand the harsh environment of a professional shop.
Auto-Ranging Capability: Automatically selects the most appropriate range for the measurement, though manual selection is typically available.
Automotive Specialized Functions: Includes modes for checking RPM, duty cycle, frequency, and dwell.
True RMS: Allows for accurate measurement of non-sinusoidal AC waveforms often found in modern vehicle electronics.
Durability: Known for a rugged design that can survive drops and impacts that would damage standard meters.
Accessories: Typically comes with standard test leads, an inductive RPM pickup probe, a temperature accessory, and a protective rubber boot. Core Operating Procedures
Before use, always inspect the test leads for damage to ensure safety and accuracy. Voltage Measurement (AC/DC):
Plug the black lead into the COM jack and the red lead into the V/Ω jack.
Set the dial to either AC or DC voltage (indicated by "V" with a wavy line for AC or a straight/dashed line for DC).
Connect the probes in parallel to the component being tested. Resistance and Continuity: Ensure the circuit is powered off before testing.
Set the dial to the Ω or continuity (WiFi-like symbol) setting. An audible beep indicates a complete circuit (continuity). Current (Amperage) Measurement:
Crucial: The meter must be connected in series with the circuit. However, none of these replace the official Blue
Move the red lead to the 10A or mA jack depending on the expected load. Set the dial to the corresponding "A" or "mA" setting. Restoring a Blue-Point Multimeter LIVE
