    6.BATTERY SAVER (SLEEP MODE) The meter w ill automatically enter the “sleep mode” if there is no function change or button press for 10minutes, but it w orks as soon as you turn the rotary function switch or push down any button 7.POWER TOOLS AND AMALL APPLIANCES This test w ould also apply to other similar equipment that has a line cord.
  • Page 12 armature, field coils and brush rigging by connecting one megohmmeter lead to each of them individually, leaving the other connected to the grounded motor housing. The above also applies to DC Gemerators.
  • Page 13 CABLES Disconnect the cable from the line. Also disconnect opposite end to avoid errors due to leakage from other equipment. Check each conductor to ground and /or lead sheath by connecting one megohmmeter lead to a ground and /or lead sheather and the other megohmmeter lead to each of the conductors in turn.
