AC MilliVolt meter

[zgeng]

mas gwen tu ada port dibelakang tlsanya local sama remote..untuk apa yah gunanya

[gwendy]

untuk lebih jelas coba baca manual book , klu gak ada googling aja pasti ketemu hehe :)

[icm]

itu memang untuk ngukur Voltage rendah misalnya signal audio, lengkap lagi sam dBnya  :D

sebelah kiri rating mV sebelah kanan rating V 40dB, 100V :D coba cari manualnya siapa tahu ada tambahan informasi...

namanya millivoltmeter tapi selektornya bisa sampe 100V / +40 dB

ok mas tk carinya

memang mas smpe sgtu harusnya volt/db meter kali ya  >:D<

secuil keterangan:
LMV-189AR/BR : 2-Channel AC Millivoltmeter
Two-pointer meter, Frequency Range 5Hz to 1MHz
High sensitivity 30 or 50uV
Range interlock function
dBm and dBV scales
Remote control function
Measurement Range 189AR: 30 µV to 100 V, 189BR: 50 µV to 150 V
Accuracy Within ± 2% of f.s. (at 1 kHz)
Frequency Response 5 Hz to 1 MHz ±10%
20 Hz to 100 kHz ± 2%
Input Impedance 10 MOhm
Monitor Output 1 Vrms at full scale meter reading
(Right and left output independent)
Dimensions(W.H.D.)/ Weight 150 x 175 x 250 mm,

The LMV-189AR/BR 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 30 mV and range to 100Vrms (LMV-189AR) or 50 mV and range to 150Vrms (LMV-189BR) maximum full scale with a wide bandwidth of 5 Hz to 1MHz. 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-189AR 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.

tak pikir ini true RMS ternyata average responding. emang buat apa rencananya mas

@fauzip...blm tau ni mas wat apa ntar..ni juga barang dpt dr iklan diintrnet belinya borongan dr osciloskop,freq counter,psu,solder blower,poweramp byk deh mas barangnya...dapat murah lagi plus msh fungsi
:-bd  :-bd

thanks infonya disecuil keterangan
