MASTECH MS8229 - Blown resistor
« on: April 07, 2015, 10:35:31 am »
Hi,

I have a MASTECH MS8229 multimeter and after an unfortunate frequency measurement it seems to have some mulfuctions.
After opening the multimeter I saw a blown resistor. It is the R33 on the main circuit board.

Can anyone (who has the MS8229) open his multimeter and tell me the Ohms of that resistor? (or anyone who has the circuit schematic)

It has the inscription 01D (same as R13, close by). I'm not sure what it means, but it measures ~100K in-circuit.

EIA-96 codet 1% resistor, that is 01 (100) multiplied by D (1000) so 100K seems abut right.
