TOA ZM-104A Impedance Meter
Mon, 1 Mar 2010The new TOA ZM-104A impedance meter has been designed to measure the impedance of the speaker lines in 100V line installations.
The TOA ZM104A meter is fully portable and is operated from internal AAA batteries. It features an easy to read analogue metre, and is used by simply disconnecting the speaker line from the amplifier and connecting it to the measuring leads.
The range selector switch allows selection of three ranges, from five to 100K ohms. A zeroing knob allows the ZM104A to be easily calibrated before each use. Battery life is greater than 30 hours of continuous use. The TOA ZM-104A is supplied with an impedance output chart and carry-case. The entire unit is sturdy, light and easy to carry.
