Basically yes. Specifically, the current sensing probe or resistor could be placed anywhere in the leads from the supply source, but the voltage sensing leads appear to be placed at the filament connections rather than the battery terminals. Otherwise, his input voltage measurement values make no sense at all but I could be missing something! -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
