Is it a pulse train or 60 hz AC? If it is PWM, the numbers won't mean that much - even an RMS meter can have trouble with narrow pulses.. I can point you to a cheap meter to read 60 hz AC sine-waves, but I am skeptical that you have 1000Vac. > > Olusegun Abode +234 8037045535 Email:[EMAIL PROTECTED] > > --- On Fri, 11/28/08, Kirk Wallace <[EMAIL PROTECTED]> wrote: > > From: Kirk Wallace <[EMAIL PROTECTED]> Subject: Re: [Emc-users] I need to > connect my > Voltmeter to actually read....
