Avo multimeter model da116
Hello all, I have a digital AVO multimeter type DA116, unfortunately, one or two segments of the LCD display are missing. I have tried to contact AVO ( IF THEY STILL EXIST? ) without success. I am quite happy to dismantle the meter to see if there and markings on the display, ie ref number. Many thanks. George.

I don't know if it's similar to the display problems old Fluke DMMs develop, but have you checked if it's just a bad contact on the zebra strip between the LCD & the PCB? this might need cleaning or replacing if the strip can be obtained.

Re: Avo multimeter model da116
On another note I am building a RF power meter, there are two eight pin SM I/Cs one which is a LT1019, a 2.5 volt regulator I/C, however, there are no markings to indicate which is pin 1 ? no dot or cutaway on the chip ? anyone any ideas
