Description:
Milliohmmeter
Information
The Keithley model 502 is a battery operated, portable
milliohmmeter for measuring resistances from 0.00003 to 1000
ohms. The instrument employs an AC testing method,
eliminating zero drift and permitting resistance readings in
the presence of DC currents.
The reading is presented an a linear scale panel meter.
Typical applications of the instrument include measurement
of contact resistance, conductivity of semi-conductor
samples, fuse and squib testing, and electrolyte conductivity.
Maximum power dissipation in the sample is 2 microwatts,
permitting the measurement of detonator fuses without danger
of detonation. In the measurement of contact resistance, the
model 502 may be considered a "dry circuit" tester. However,
the instrument may be used in the presence of DC biasing
currents to measure the change in resistance caused by these
currents.
