(Measurement categories) EN 61010-1:2001 specifies the measurement categories and
their requirements as follows. The 72-6802 falls under category II.
• Measurement category IV is for measurements performed at the source of low-
voltage installations.
• Measurement category III is for measurements performed in building installations.
• Measurement category II is for measurements performed on the circuits directly
connected to low voltage installations.
• Measurement category I is for measurements performed on circuits not directly
connected to mains.
Power Supply
•
AC Input voltage: 115V/230V AC, 50/60Hz
• The power supply voltage should not fluctuate
WARNING
more than 15%.
•
To avoid electric shock, connect the protective
grounding conductor of the AC power cord to
an earth ground.
Fuse
• Fuse type: T0.63A/250V (AC 115V),
T0.315A/250V (AC230V)
WARNING
•
Make sure the correct type of fuse is installed
before power up.
•
To ensure fire protection, replace the fuse only
with the specified type and rating.
•
Disconnect the power cord before fuse
replacement.
•
Make sure the cause of fuse blowout is fixed
before replacing the fuse.

instrument.
•
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into the instrument.
•
Do not use chemicals containing harsh products
such as benzene, toluene, xylene, and acetone.

Temperature: 0°C to 40°C
(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements
as follows. The 72-6802 falls under degree 2.
Pollution refers to "addition of foreign matter, solid, liquid, or gaseous (ionized gases),
that may produce a reduction of dielectric strength or surface resistivity".
• Pollution degree 1: No pollution or only dry, non-conductive pollution occurs. The
pollution has no influence.
• Pollution degree 2: Normally only non-conductive pollution occurs. Occasionally,
however, a temporary conductivity caused by condensation must be expected.
• Pollution degree 3: Conductive pollution occurs, or dry, non-conductive pollution
occurs which becomes conductive due to condensation which is expected. In such
conditions, equipment is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature nor humidity is
controlled.
