  • Page 8: Operation

    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. Auto Power-down mode If unused for about 30 minutes, the tester will power-down automatically.
