Self test Error codes

 

Hi,

I am running portable now away from home. I am not getting useable reading from my AA-230 zoom.?

Self test shows error code 33 on the first test and error code 101 on the second and my 50 ohms resistor is at home.

can you help, I have my laptop with AntScope installed. Unit has worked well in the past.

thanks N2OG Scott?
 

Hi Scott,
?
Did I understand you correctly that earlier everything was OK with the analyzer, but now the analyzer doesn't measure correctly?
?
Best regards, Alex
 


Hi Alex,

That is correct.? It does not want to measure SWR direct or via AntScope.?

Thanks for the reply?

Scott,

In this case, there is a high probability of analyzer breakdown - damage by static discharge to the measuring bridge elements (SMD resistors and microchips).

You can contact one of the partner service centers:?
Or try to repair the analyzer yourself, the circuit is publicly available.

Ok, ?

Would that likely be caused by operator error! Or a procedure not followed??? I don¡¯t want this to happen again.

If the antenna is not a closed system (dipole, GP, Yagi, etc.), then a charge of static electricity may accumulate on the antenna. When the cable is connected to the analyzer, a high voltage current will flow through the analyzer's measuring bridge elements and cause damage.
The picture shows an example of burnt-out resistors.

Always short-circuit the connector pins on the cable before connecting to the analyzer for a few seconds.
This neutralizes static electricity and prevents damage to the analyzer.
 

I understand, could connecting it to a computer do the same thing?
I guess anything is possible.

Connecting the analyzer to a PC will not damage the bridge.

But sometimes (very rarely) it can cause a malfunction of the power circuits. But in this case, the analyzer will not turn on at all.
 

Ok Alex, Do both of these look bad to you ?
I think the one with a 5 on it looks cooked. ?The 2700 looks suspect as well.

What do you think?

Hi Scott.
Definitely, the resistors are fried.
Its needs to be replaced.

In general, in this case, it is recommended to replace all seven bridge resistors.
Three resistors 51 ohms.
Two resistors 27 ohms.
Two resistors 270 ohms.

Important! Resistors Tolerance - 1%
