HN-31						Bulletin No:
Dummy  Load					HN-31-1

		                        Service Notes

Over the last two or three years, we have had problems with resistors in
the HN-31 dummy load.  They are not sealed properly, becoming soaked in
oil and increasing in value.  Even though the customer is using the
proper load, you will have calibration problems due to the change in
resistance.

All stores should check their HN-31 Dummy Loads from time to time, for
proper value.
