Immediately displays the DC or AC magnetic field.

Warm-up time is only 1/2 second, and there are no initial calibrations or adjustments required. Operates on a 9V battery or AC adapter (110-240 VAC), so the meter can be left permanently on if required.

Can be rapidly scanned across a part to check magnetization.

An alarm sounds only where the field magnitude exceeds the level that you set or where the field is between two levels you set. The alarm response time is 2 milliseconds, so it can be scanned quickly. The alarm can be used either to check for any residual magnetism or to sound if a magnet is out-of-spec (by setting the upper level just below the minimum acceptable field).

When set to the Peak/Hold mode, it displays the maximum field encountered since the last time "Reset" was pressed.

The Peak/Hold response time is also 2 milliseconds, so after scanning a surface, the meter can detect and display any very brief peak (spike) that was encountered as well as a slow one. The peak displayed includes the polarity sign, and the value will be held in memory until you reset it or turn off the meter.

Offset, if required, is manually adjustable.

There is also a "Relative Zero" function. Several interchangeable probe types are available, and the meter automatically detects the probe type.
