Blue Point Mt596a Multimeter Manual May 2026
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).
Since Blue Point manuals are often hard to find directly online, these features are based on the standard specifications for this model (CAT III automotive DMM).
The Blue Point MT596A multimeter manual is more than a booklet – it’s the key to accurate diagnostics and personal safety. While Blue Point/Snap-on has made recent manuals harder to find online (pushing users to official channels), persistence will pay off. Use the official Snap-on support portal, contact your local dealer, or request a PDF via email.
Remember: A $200 multimeter without its manual is a paperweight. With it, the MT596A is a precision instrument capable of everything from parasitic draw tests on a modern BMW to dwell adjustments on a 1967 Mustang. Don’t guess. Get the manual.

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.

Here’s a clear, structured text that you can use as a placeholder / reference guide for the Blue Point MT596A Multimeter — useful for a quick-start manual, tech sheet, or tool crib document.
Note: Blue Point (by Snap-on) does not officially list an "MT596A" model in current public catalogs. This text is synthesized from common features of their digital multimeters (e.g., MT596, MT596B) and standard DMM operation. For an exact factory manual, contact Snap-on Industrial or check their service portal.

Snap-on’s support website primarily hosts manuals for current-production tools (like the new Blue Point multimeters with color displays). The MT596A was manufactured between 2008 and 2015. Consequently, it is considered a "legacy" product. Official paper manuals were often lost or thrown away as technicians moved toolboxes.
The good news? The MT596A is functionally identical to several other meters (e.g., the Cen-Tech P37772 and older Extech EX330). However, the button layout and fuse ratings are unique to Blue Point. Using the wrong manual could lead to incorrect fuse replacement or misinterpreting the "REL" (relative) mode.
A: No. You likely have the dial on Ω (resistance) or mA (milliamps). Turn to DCV. The manual has a warning table for exactly this error.
⚠️ Warning: Blowing the 500mA fuse is common. Do not replace it with a higher rating. The MT596A requires a 6x32mm ceramic fast-blow fuse. Automotive blade fuses will not fit.
