KRA-4000M
DIGITAL INSULATION TESTER
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
