Is there any problem using a VOM instead of a DMM to perform the
resistance checks while building the K3?
As long as the negative side of the internal battery that is feeding the
resistance measurement circuit is applied to the ground side of whatever
is being measured in the K3 during the check, and the open circuit
voltage of the ohmmeter is not more than 3 volts, it should be safe.
Some VOMs used a 9V battery in the resistance circuit and/or tied the
positive side to the "black lead." At least, some of my old VOMs did.
