1.3 Setting the LINE SELECTOR Switches
The super megohmmeter can be operated from one of the AC line voltages of
100 V, 120 V, 220 V and 240 V by setting the LINE ELECTOR switches to
the specific positions, respectively.
Confirm the switch setting to the specific positions in accordance with Fig.
1.1.1. If they are not set properly, correct their positions, accordingly.
To change the position of the switch, insert the tip of a flat
blade screwdriver into the slot of the switch lever, and slide the
leverupward or downward.
CAUTION
Before connecting the power cord to the AC outlet socket, confirm that
the LINE SELECTOR switches on the rear panel are set to the
positions, accordingly (See 1.3 Setting the LINE SELECTOR
Switches.).
CAUTION
To change the LINE SELECTOR switch positions, unplug the power
cord plug from the AC line socket to prevent a possible damage.
When the switch position is changed while the voltage is on, the
switch contacts will be damaged.

The LINE SELECTOR switches have two positions – up and down.
Slide the switch lever to either position until it stops.
Do not leave the lever at a neutral position. If the lever is set at
A neutral position, a normal function cannot be obtained, and
