Implies the regulation for impulse withstand voltage.
“II” applies to electrical equipment which
is supplied from the fixed installation like a
distribution board.
*2 Pollution degree 2:
Describes the degree to which a solid, liquid,
or gas which deteriorates dielectric strength or
surface resistivity is adhering.
“2” applies to normal indoor atmosphere.
Normally, only non-conductive pollution occurs.
*3 Measurement category II:
Applies to measuring circuits connected to low
voltage installation, and electrical instruments
supplied with power from fixed equipment such as
electric switchboards.

A/D Calibration Value
Two types of A/D calibration values (factory
shipment setting and user setting) can be saved.
If the user setting is not proper, it can be restored
to the calibration value at factory shipment.
