Binghamton, NY Nov ten, 2009 #seven I'm not familiar with meter operation, but I'd suspect that it needs to send the switching voltages (13v for odd and 18v for even). And, if you need to see the opposite sats it ought to send out the 22khz tone. Hard disk drive https://wakelet.com/wake/fh7l2ynHp72F-mz8odCRr
