DANGER
■
Do not operate the super megohmmeter in the presence of flammable gas.
There is s possibility of an explosion and/or fire.
■
Do not touch the Rx ‘–‘/’+’ measuring terminals on the front panel of the
SM-8216 during measurement. They output a maximum measuring
voltage of 1000 V.
WARNING
■
Ground the ground prong of the power cord plug to avoid electrical
shock.
If the ground prong cannot be grounded, connect the GND terminal on the
rear of the instrument to a ground. When the power
cord plug is connected
to the AC line socket via an accessory 3-prong to 2-prong adapter, the
green ground tab of the adapter to the ground.

■
Before turning on the power switch for the instrument, check
that the LINE SELECTOR switches are set for your local AC line
voltage. If the wrong AC line voltage is applied to the unit, it will
be damaged (higher voltage supply) or will not function properly
(lower voltage supply). See 1.3 Setting LINE SELECTOR Switches
for switch setting. Use the right size and amperage power fuse. If a fuse
of incorrectamperage is inserted into the fuse holder, the unit will be
damaged. See 1.4 Checking the Fuse Amperage for a correct fuse
