One does not tell the pc anything about the meter or its reads ever, except to indicate an F/N.
Steering a pc with "That – That – That" on something reading is allowable. But that isn’t putting attention on the meter but on his bank.
Definition of "In Session" is "Pc interested in own case and willing to talk to the auditor".
Saying "That reads", "That didn’t read", "That blew down" is illegal. It is no substitute for TR 2. It violates the In Session definition by putting pc’s attention on the meter and can make him very unwilling to talk to the auditor!
