DANGER
• Use the neutral side (ground side) of the commercial
power supply for this measurement. Prior to
connection, use a voltage detector etc. to make sure
that it is going to be connected with the neutral side
and take caution for electric shock.
• This device can be connected to the neutral side of
an outlet with a voltage-to-ground of 300 V or less,
or to the wire on the neutral side of the breaker's
secondary side with a voltage-to-ground of 150 V or
less. Do not connect with anything other than those
specied above. It can be hazardous.
WARNING
• Use the optional test lead L9787 for simplied
measurement for safety. Connecting the
measurement cables L9841, L9842-11, L9842-22,
L9843-51 and L9843-52 to a commercial power
supply may cause electric shock.
• This device can output a voltage of approx. 30 V.
Although the device has a dust-proof, jet-proof and
water-proof structure, the device should always
be dried before using it for measurement so as to
avoid electric shock.
