6.BATTERY SAVER (SLEEP MODE)

The meter will automatically enter the “sleep mode” if there is no

function change or button press for 10minutes, but it works as soon

as you turn the rotary function switch or push down any button

7.POWER TOOLS AND AMALL APPLIANCES

This test would also apply to other similar equipment that has a line

cord. For double insulated power tools, the megohmmeter lead

shown connected to the housing would be connected to some metal

part lf the tool(e..g chuck,blade).

Note: The switch of the device must be in the “ON” position and the

main power should be disconnected.

MOTORS

AC-Disconnect the motor from the line by disconnecting the wires at

the motor terminals or by opening the main switch. If the main switch

is used and the motor also has a starter then the starter must be

held, by some means, in the “ON” position. In the latter case, the

measured resistance will include the resistance of the motor, wire

and all other components between the motor and the main switch. If

a weakness is in dicated, the motor and other components should

be checked individually. If the motor is disconnected at the motor

terminals, connect one megohmmeter lead to the grounded motor

housing and the other lead to One of the motor leads.

DC-Disconnect the motor from the line. To test the brush rigging,

field coils and armature connect one megohmmeter lead to the

grounded motor housing and the other lead to the brush on the

commutator. If the resistance measurement indicates a weakness,

raise the brushes off the commutator and separately test the
