Question no.1 (ask on 13/01/2015) : Hello, I have a C.A 6250. After a few measurements (250 mOhms 10A), the instrument displays "ERR 005" - internal temperature too high. What does this mean?
answered on 14/01/2015 :
Hello,
The current source of the instrument is protected against overheating.
If a 10 A measurement lasts too long (more than several tens of seconds), it causes the temperature to rise, so the current is cut off and the instrument displays Err 05.
The instrument must be left to cool down before performing another measurement. This is a safety feature to prevent damage to the instrument.
