NF ZM2354 LCR meter ERR77?
« on: November 18, 2017, 12:59:04 pm »
I got a NF model ZM2354 LCR.
It worked fine until last time I turned on it, It didn't execute normal boot sequence,but displayed "IL ERR 77".
I asked another friend who have some ZM2354, he sadly told me that all of his 2354 also have the same problem----IL ERR 77
Most ERR 77 happened after normal use several times. I check manual it only shows ERR77 is "hardware problem". What hardware problem?
Anyone know how to solve this problem? Thank you very much...

Seems your lcr had some beating on the top panel case ??? could not find a complete manual ...

Does it have some battery inside ?

Maybe some loose part, connector, socketed chip, or even bad/cold solder ?
