my photo ok??
i am ready to turn on dbt...
god help me...
lol

 

[gene french]

i can also verify chassis is not shorted to b+ or b-
as per directions....

 

[gene french]

dvm bright then dim...
relay engaged...
offset 7 mv dc

[gene french]

-7 mv rather....as shown in the meter in the above pic...
i think that is ok....
no kaboom, smoke, or sparks....
did not throw the breaker to the bed room....
didnt even dim the lights momentarily...

7mv is not a good reading. Both channels the same?

1 mv or under is a good reading. Have you (carefully) checked around with your voltages?

Boring start-up... the best kind.

Double check using all of your meters, from what I remember you don't have real good meters.

 

[George S.]

And you said once that you had +-60 VDC when it should have been +-80 VDC. Bum meter?

 

[gene french]

that was the right channel....
no sir these meters are the finest that china has to offer....
when i started with the sx...i never dreamed i would end up here...
i would have got a variac and much better meters...
besides my kid would just leave them in the rain anyway...

And you said once that you had +-60 VDC when it should have been +-80 VDC. Bum meter?

that may have been on the dbt also...dont remember....
that would account for low voltage...
i will read b+ and b- with dbt switched out....on normal current....
and start there...

 

[gene french]

b+ is +81.9
b- is -81.9
left offset stabalized around -000.8
right offset stabalized around -002.3
what other voltages do i check????

 

[gene french]

- 000.8 and -002.3 are both under 001.0

 

[Gepetto]

- 000.8 and -002.3 are both under 001.0

HUH??? You slip a decimal there?

 

[gene french]

- .8 mv or -.0008 v
- 2.3 mv or -.0023 v
sorrt about the confusion

 

[gene french]

both are less than 1 mv or .001 v...

 

[Vynuladikt]

both are less than 1 mv or .001 v...

the important value is the difference from "0.000" -0.0023 is still more than 0.001 from zero.
