| Well for the resistor chain that includes R5, starting at top, 90K then comes 9K, then comes R5, then comes 100 ohm - logic dictates that R5 units should be ohms (900 ohms). R18 indicates 2K2W (2.2K ohm) A number of service manual copies (one erroneously indicates it is for a DVD): http://elektrotanya.com/?q=showresult&megnev=&megnev2=M-830b&kategoria=&kat2=all |

| I was delighted to locate a data sheet for my MASTECH M-830b multimeter. I have blown R5 and R18 and you had the perfect sheet to discover what values I need for replacing. HOWEVER I was not able to read the values. I got 900 for R5 but not the units and R18 was totally unreadable. I have sent emails to Hong Kong for values but they don't reply. Yes I know this is a cheap meter but I like the challange!! Red Dragon |
