hi, i should of explained better! the bench meter i fixed is a old but good RACAL with 5 1/2 digits, on it there is 5 sockets, 2 for ohms reading and 2 for volts then there is a socket marked guard. apparently the meter will do 2 or 4 wire measurments as there is a switch on the front that says 2 wire/4 wire. i just
wasnt sure if i needed special probes like on my LCR meter with 4 wire, and
what is the guard socket for? i also have that on the LCR
as for the little gould 400 oscilloscope i am in with a chance as i have found the service manual
