    Hi all
    I have an older Leader LMV-181A AC Millivoltmeter, i wanted to know if
    it can be used with an RF Probe, to read rf voltages (i don't think so) as
    the output from the rf probe is dc.

    Can some form of bridge rectifier be used to overcome\convert the volt
    meter so that it reads a dc voltage ??
    Regards

    Yes it will work input the signal into the pl59 socket as long as the frequency is under 1Mhz.

    Hi Dodgy
    Thanks for that reply.
    Why frequency is under 1Mhz ?.
    I thought that the rf probe, takes the rf voltage at whatever the frequency
    that the diode in the probe works at, and gives out a dc voltage to drive a
    dc millivolt meter. I don't think that it is frequency dependent, it's just a dc
    voltage, is it ?
