OPERATION Before taking any measurements, read the Safety Information Section. Always examine the instrument for damage, contamination (excessive dirt, grease, etc.) and defects. Examine the test leads for cracked or frayed insulation. If any abnormal conditions exist do not attempt to make any measurements. - Page 9 5. Use caution when measuring 10 amps on 10A range for 60s, please waiting for 10 minutes for next measurement of 10 amps for safety reason. Resistance and Continuity Measurements 1. Set the Function/Range switch to the desired resistance range or continuity position.
- Page 10 Diode Tests 1. Connect the red test lead to the "VW " jack and the black test lead to the "COM" jack. 2. Set the Function/Range switch to the " " position. 3. Turn off power to the circuit under test. 4.
