Product Information
Full details
The VOLTCRAFT MS-440 Magnetic Field Tester is designed for electricians, technicians, and hobbyists who need to quickly verify the presence and function of magnetic fields in electronic components. Its key benefit is contact-less detection, allowing for efficient testing of relays, solenoids, and other inductive loads without disassembly. A potential caveat is that it detects the presence of a field but does not quantify its strength.

Extended Product Information
FAQs
What types of magnetic fields can the MS-440 detect?
The VOLTCRAFT MS-440 can detect both constant (DC) and alternating (AC) magnetic fields.
Does the MS-440 measure the strength of the magnetic field?
No, the MS-440 is designed to indicate the presence of a magnetic field, not to quantify its strength. It provides a visual and audible alert when a field is detected.
What components can I test with the MS-440?
You can test components like relays, magnetic valves, coils, solenoids, and other inductors that carry current and generate a magnetic field.
Do I need to open the casing of the component to test it?
No, a key feature of the MS-440 is its contact-less detection capability, meaning you typically do not need to open the casing of the component being tested.
How do I know if the tester is working?
The tester works by detecting magnetic fields. You can test its functionality by bringing it near a known source of a magnetic field, such as a powered solenoid or a strong permanent magnet, to see if the probe lights up and an audible signal is produced.
What is the power source for the MS-440?
The specific battery type is not detailed in the product information, but like most testers of this type, it is battery-powered. Ensure the battery is correctly installed and has sufficient charge for operation.
Troubleshooting
No indication when near a component that should be magnetic.
Ensure the component is actually energized and generating a magnetic field. Check the power source and connections to the component. Move the tester closer to the suspected magnetic source.
Intermittent or weak signal.
Replace the battery if it is low. Ensure the probe tip is clean. Test the tester on a known magnetic source to verify its functionality.
Audible indicator not working.
Check if the battery needs replacement. If the visual indicator works but the sound does not, there might be an internal issue with the speaker. Ensure the ambient noise level is not overwhelming the sound.
Pros and Cons
Pros
- Allows for quick and easy identification of magnetic field presence.
- Contact-less testing reduces the risk of damaging components or connectors.
- Audible and visual indicators provide clear feedback.
- Durable construction withstands rugged use.
- Compact and portable with a convenient shirt-clip.
Cons
- Does not provide quantitative measurements of magnetic field strength.
- May require proximity to the component to detect weaker fields.
- Audible indicator might be difficult to hear in very noisy environments.
Setup, Compatibility & Care
Setup: The MS-440 requires no setup. It is ready to use out of the box. Ensure the battery compartment is securely closed before use.
Compatibility: This tester is designed to detect both constant and alternating magnetic fields and is compatible with components such as relays, magnetic valves, and coils.
Care: To maintain optimal performance, keep the probe clean and free from dust and debris. Wipe the casing with a dry or slightly damp cloth as needed. Avoid exposing the device to extreme temperatures or moisture. Store in a dry place when not in use.
