2. Select the “2Ω” or ”20Ω” Range.
3. Engage 2 Alligator clips to short-circuit both of them.
4. Save the Rk values with reference to “8-2-7 Setting for the residual
resistance (Rk) on the Test Leads”.
Note) A break in Test Leads or burnout of Fuse is suspected when the
LCD shows “Rk=OL Ω” while 4 Test Leads are being shorted.
