sxc 1901F from a micronta multimeter 22-193

[alpibucky]

Hello,

Does anybody have a datasheet of this IC.
My 22-193 readings are wrong and the BATT indicator appears
continuously, but the batteries are good.

With my kind regards,

Alpibucky

Could it be a dual comparator, NJM2903D ?
The RS parts list seems to indicate that as a possibility.
If the chip is a comparator, the circuit is likely dividing
the battery voltage, and comparing the result to a reference.

That said, examine the battery connections, and circuit path
from the battery to the PCB's. More likely the problem
is in the path somewhere, than a defective IC.

AFAICT, the SXC1901F was manufactured by Seiko Instruments.

FWIW, the following document lists a service manual, cat# 10824373, NP
Part # MS2200193.

once those Radio Shack multimeters go astray, that is usually it for it. Go
buy a fluke.

I found a supplier for this part made by Sieko, are you still interested?
