wavetek dm27xt

Resistors R30 and R31 on pcb 4233-1288d-b are burnt beyond recognition and need to be replaced. They conect directly to the voltage and resistance measurement terminal on my wavetek multimeter. I have searched everywhere for a wavetek dm27xt digital multimeter schematic in order to find out their sizes and types.
Anyone who can help?
 

Hi owenshaba,

I opened mine and here it is :
R30 = Brown/Black/Brown//Gold
R31 = Yellow/Purple/Black//Gold
 

Re: wavetek dm27xt


r31 is 47 ohms ,r30 is 100 ohms..I had a similar multimeter it was a great instrument until it was zap by the focus voltage of the tv i was repairing..it is still not working good luck on yours ! PCB No. is the same 4233-1288E-B
