This is the most advanced handheld DMM. It features auto/manual ranging, fast bar graph, and Max/Min/Ave/Data Hold.  The 10MHz frequency counter has 0.01Hz resolution in the low range. It also features dBm measurement, true RMS, 20kHz ACV bandwidth and better accuracy. With the selected reference impedance the meter can measure and automatically calculate the dB gain of amplifiers or insertion loss of filters, attenuators, etc. The twenty reference impedance are 4, 8, 16, 32, 50, 75, 93, 110, 125, 135, 150, 200, 250, 300, 500, 600, 800, 900, 1000 and 1200Ω . DMM 89 is also equipped with true RMS sensing circuit for accurate measurement of non-sinusoidal waveform such as distorted sine wave, square wave, saw tooth, pulse trains and SCR chopped waveform. The very wide bandwidth of 20kHz for ACV measurement makes it ideal for audio works. This DMM is excellent for audio and communication. Complete with holster, leads, battery and manual.
