Peter,
Semantically you are absolutely correct. They cannot hold the shipment.
Pragmatically, it ends up that way. If I can't apply the logo I can't ship the

Your comment triggers another comment: Leadership.
Typically, we tend to let the inspector be the

The host can be the leader.

Hi Folks
I second Rich's comments - the same things have happened to me a few years
ago, and did result in a temporary shutdown on one occasion but rapid
discussions with the agency engineer gave us a few weeks to fix the problem
and so we could restart production virtually straightaway.

If the load in question is a resistance heating load, I can see two ways
around the problem:
1. Use a circuit much like a triac light dimmer. Make sure the control is
smooth enough that the flicker standard is met - no sudden changes in
current.
I would suggest using the new version as it has been recognized by the
FDA for submission in your 510K. I had thought it was published in the
OJ also but I must have been mistaken.

I have found that using ammeters at low voltages, the input resistance will
interfere with the current measurement and give you a lower value. I use
precision 0.1 ohm resistors in parallel, and measure the voltage across the
resistors.

The usual reason for doing this is to eliminate testing when the configuration
changes.
e.g. If the power remains the same then the thermals will be within the same

To benefit from this most you should load up the module (extra resistor on
