Blue Point Mt596a Multimeter Manual Review

Since Blue Point discontinued this in the late 1990s, your best bet is:

Bottom line: The MT596A is a robust industrial meter. If yours still works, protect it. The input jacks are the first to fail. If you get OL on every voltage range, check the internal PCB traces near the fuse holder – they crack.

Reply if you need the calibration procedure (potentiometer locations inside).

The dial has 8 primary positions:

Blue Point (a brand of Snap-on Inc.) often shares hardware with Fluke. The MT596A is functionally equivalent to the Fluke 87 (early series) or Actron CP7677. If you cannot find the exact Blue Point PDF, search for the Snap-on "EETM596A" or Fluke 87 Series I manual – the functions and button layout are identical.

Blue-Point MT596A is a specialized digital multimeter (DMM) designed primarily for automotive professionals. It stands out for its high durability and specific measurement capabilities that go beyond standard household multimeters, such as frequency counting and pulse width. Essential Automotive Diagnostic Capabilities

Unlike basic meters, the MT596A includes functions specifically tailored for vehicle systems: RPM & Ignition Testing

: It can measure RPM using an inductive pickup and provides duty cycle and dwell measurements, which are critical for diagnosing fuel injection and ignition systems. Sensor Diagnostics : Technicians use it to check specialized components like ABS sensors oxygen (O2) sensors intake air temperature sensors fuel pressure Precision Voltage Testing : It measures both AC and DC voltage

, allowing for testing of everything from standard 12V batteries to AC signals on digital Mass Air Flow (MAF) and wheel speed sensors. Resistance & Continuity

: It is used to determine the health of coils, spark plug wires, fuses, and fusible links. Key Hardware & Operational Features Auto-Ranging

: This feature automatically selects the appropriate measurement range, ensuring accurate readings without manual adjustment. User Interface : It features a high-contrast 2000-count LCD display for easy reading in various lighting conditions. Ruggedized Design

: Typically housed in a protective rubber boot, the MT596A is built to survive the drops and impacts common in a shop environment. Power Source : The unit is powered by a standard 9V battery , which is easily accessible through the back cover.

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. Since Blue Point discontinued this in the late

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.

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 Bottom line: The MT596A is a robust industrial meter

Since Snap-on/Blue Point does not publicly host the full PDF manual for legacy models, this post compiles the essential operating instructions, specifications, and symbol meanings you would find in the original manual.

Title: Blue Point MT596A Multimeter Manual – Operation & Specs Posted by: Toolroom Tech – [Solved]

I couldn't find an official PDF from Snap-on for the legacy MT596A, so I pulled the critical info from the original user guide and spec sheet. This meter is a rebadged Beckman Industrial (Wavetek) unit.

Here is the practical manual you need.

Since Blue Point is a subsidiary of Snap-on Incorporated, the manual is not available on generic sites like ManualsLib in many cases (they often host older versions). Here is the legitimate strategy to get your PDF:

Q: The display shows a random number even when leads aren't touching anything. A: Normal for high-impedance input. Short the leads together – it should read 0.0 ohms or 0.00V. If not, clean the jacks with DeoxIT.

Q: No continuity beep, but ohms work fine. A: You are likely on the Ω setting, not the ))) setting. Turn dial to the diode/continuity position (looks like an arrow with a plus sign and sound waves).

Q: Can I use this on a car's alternator AC ripple? A: Yes. Set to ACV (200V range). Reading should be <50mV AC. If >100mV AC, the alternator diodes are failing.

To understand the manual, you must understand the tool it describes. The MT596A is an automotive-centric multimeter.
