Blue Point Mt596a Multimeter Manual (2026)

The MT596A is rated for specific electrical categories. Never exceed its maximum voltage thresholds.

: The meter must be connected in series with the circuit.

Install a matching fuse with the exact same speed and amp rating (typically a 400mA fast-acting fuse and a 10A high-energy fuse). 5. Troubleshooting Common Issues Probable Cause Corrective Action Dead or missing internal battery Replace the 9V battery Inaccurate DC voltage readings Low battery voltage corrupting logic Install a fresh alkaline battery No response on Amps setting Blown internal fuse Open the casing and replace internal fuses OL displayed during test Value exceeds chosen range Switch to Auto-Range or select a higher range

Observe the reading. A standard modern vehicle should typically draw less than 0.050 Amps (50mA) after modules go to sleep. Maintenance and Battery Replacement

The red lead plugs here for measuring high electrical current up to 10 amperes. Step-by-Step Operating Instructions 1. Measuring DC Voltage (Vehicle Batteries and Circuits) Plug the black lead into COM and the red lead into V . Turn the rotary dial to the V position. Press SELECT until the display shows DC . blue point mt596a multimeter manual

Your Blue Point MT596A is an investment. Proper care will keep it accurate for years.

, Hz), and specific modes like (Direct Current) or AC (Alternating Current). It also includes a low-battery indicator icon. 2. Primary Function Buttons

Touch the test probes across the circuit or component under load.

The common ground or negative return terminal. Used for every single test. The MT596A is rated for specific electrical categories

: Features auto-ranging for easier operation and a digital LCD display with a bar graph to help detect intermittent signal changes.

Check the two internal fuses. Replace only with exact equivalents: Low Current: 400mA, 1000V fast-acting ceramic fuse. High Current: 10A, 1000V fast-acting ceramic fuse. Common Error Codes and Troubleshooting Probable Cause Corrective Action Display reads "OL" during a test Value exceeds selected range, or open circuit Switch to a higher range or check for broken wires. Inaccurate or erratic voltage readings Low battery voltage affecting ADC reference Replace the 9V battery immediately. No response on Amperage settings Blown internal ceramic fuse Open rear case and replace the 400mA or 10A fuse. Buttons unresponsive Active "HOLD" mode enabled Press the HOLD button to unlock the live display.

Connect the test probes across the circuit or component under load (parallel connection). Read the voltage value displayed on the screen. Testing Resistance and Continuity Install a matching fuse with the exact same

Based on similar models (like the Blue Point MT594A), you can expect the MT596A to include the following core features:

Remove the old battery and replace it with a fresh 9V battery, noting the correct polarity. Reinstall the cover and tighten the screws. Replacing the Fuses

Insert the into COM and the Red lead into V/Ω/Hz . Turn the rotary dial to the Ω position.

Switches the meter from auto-ranging (default) to manual ranging. Press repeatedly to cycle through decimal positions. Hold to return to auto-range.
