Insert the red and black test leads, terminated with the ap

4、propriate prods or clips, to their respective + and - terminal sockets. 3.Short the test lead prods or clips together. Set the selector switch to 2 . 4. Press the Test push. Check that the instrument reads zero. If a higher resistance reading is obtained check all connections. If the reading remains

5、 high, suspect that the test leads may be at fault, or that the 2A non replaceable fuse has ruptured. Continuity Testing 1. Set the selector switch to 2 , or 200, as appropriate. 2. Connect the test leads across the isolated item / circuit under test. 3. Press and hold the Test push button; allow th

6、e needle to settle. There is a separate scale for each range so each reading is direct. Take the reading from the appropriate scale of the instrument. 4. Release the Test push button and disconnect the test leads. Insulation Testing 1. Set the selector switch to 200 M. 2. Connect the R e d test lead

7、 to earth, equipment frame, or cable sheath etc. 3. Connect the Black test lead to the circuit under test or cable core. 4. Confirm that Voltage is not indicated on the instrument. (BM100/4 only) 5. Press and hold the Test push; allow needle to settle, and take the reading from the top scale of the

8、instrument. 6. Release the Test push button. 7. Wait a few moments before disconnecting the test leads, to allow any circuit capacitance to discharge. The BM100/4 will automatically monitor the discharge on its Voltage range, indicating when it is safe to remove the test leads. Resistance Testing (B

9、M101/4 only) 1. Set the selector switch to the 1M resistance range. 2.Connect the test leads across the isolated item / circuit under test. 3. Press and hold the Test push button, allow the needle to settle. Take the reading from the 1M range scale. 4.Release the Test push button and disconnect the
