when measuring jfets for biasing do i need to take my meters impedance 10 meg into account and add that to the circuit

If you're measuring the transistors in-circuit, i would say no. Unless your bias network introduces an impedance large enough to make the extra 10M in parallel significant ;)

thank you for the the reply i got confused i thought my meter might be effecting it but it depands were your meter probes measure where where your negative and positave they get 2 different readings that depends
