ZM1 / ZM1P

ZM1P The Model ZM1 & ZM1P are unique test and measurement instruments that are useful to every sound contractor or installer.

The ZM1 measures the impedance of loudspeakers and entire distributed loudspeaker systems as well as individual components (resistors, capacitors, inductors). It will also calculate the wattage that will be produced on an installed loudspeaker system.

The ZM1P(shown here) has all the features of the ZM1 but adds an Overload Protection Circuit that prevents the meter from being damaged from amplifier output overloads up to 120VAC and a Tone Generator to improve system testing and performance.

These are rugged hand held battery powered instruments with special circuitry to prolong battery life. They come complete with high quality test leads.
