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.
