Greetings to the Time Nuts List
I have a HP-5335A counter that has worked well for me for several years.
Now when turning it on I get a Fail 4.6 readout on the display.
The manual indicates that a 4.6 fail code indicates
"MRD Counter problem in Reg-E or T"
I found in the manual that you should run diagnostic 9 and 10 for this
condition.
Test 9 returns many changing 4 decimal place numbers 10.abcd , 12.defg ,
14.xqrg etc.
Test 10 returns many changing one decimal place numbers ie 15.9 , 16.1 ,
16.4 , 15.8 etc
Any thoughts or recommendations on pining down the cause and solution for
this
condition would be appreciated.
Thanks, Gordon WA4FJC
