It's interesting what you're saying there, Howard ... about (some) tests not being included in OEM procedures.
Are you referring to the "new" (latest, current) FX8?
As you may be aware, there are folk about who insist that we should "always follow the manufacturer's procedures".
Am I right in assuming that the 30-40 minute PM you mention is carried out using Datrend test equipment?
How often, do you suggest?
