| The LMV-186A is an average responding rms reading ac millivoltmeter applicable to a wide range of general purpose dual channel measurements. The model features high sensitivity of 100 m V and range to 300 V rms maximum full scale with a wide bandwidth of 5 Hz to 500 kHz. Meter scales are conveniently calibrated in millivolts and dB (0 dBV = 1 V and 0 dBm = 0.775 V) with accuracy's to within ± 2% f.s.
The meter has concentric dual channel meter movements with separate needles on the analog display and a channel reverse switch. For stereo audio, the LMV-186A is very apt for measuring record and playback levels, channel separation. balance and tracking tests of volume, loudness and tone controls versus frequency, etc.
The flat bandwidth of the amplifier output terminals often permits it to be used as sensitive accurate instrument preamplifier. Other areas of use include test and repair for communications, IF and ultrasonic circuits and systems. |
