Ken, Most multimeters, when used for AC measurements, do in fact read RMS values. Specialized meters do exist which will read peak (or average, or whatever), but the common meters do read RMS only. If you measure your household AC voltage (in the US) with your meter, and you find a reading somewhere about 115 or 120 volts, you can be assured that the meter is displaying RMS values.
You CAN use peak (or other) measurements and convert to RMS so the given formulas will work correctly, or you CAN create your own formulas which match the units that your meter does provide - but for my taste, it is far easier to just use an 'ordinary' DMM. 73, Don W3FPR > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Ken Bessler > Sent: Sunday, October 23, 2005 9:53 AM > To: Elecraft Main Group > Subject: [Elecraft] DMM for XG2 testing > > > Does a multimeter used for MDS testing with the XG2 > *have* to be one that reads RMS? > > > 73 de Ken KGØWX - Flying Pigs #-1055 > Elecraft K2 #4913 - Kadiddlehoppers #11,807 > > _______________________________________________ > Elecraft mailing list > Post to: [email protected] > You must be a subscriber to post to the list. > Subscriber Info (Addr.
