Precautions Before Use
General guidelines
CAUTION
 Make sure that the voltage input level does not exceed
DC1200V/AC1000V. (Limitations apply, please see
the specifications)
 Make sure the current input level does not exceed
20A.
 Do not place any heavy objects on the GDM-8245.
 Avoid severe impact or rough handling that leads to
damaging the GDM-8245.
 Do not discharge static electricity to the GDM-8245.
 Use only mating connectors, not bare wires, for the
terminals.
 Do not perform measurement at the source of a
low-voltage installation or at building installations
(Note below).
 Do not disassemble the GDM-8245 unless you are
qualified as service personnel.
(Note) EN 61010-1:2001 specifies the measurement categories and their
requirements as follows. This instrument falls under category II and III. (1200V
CAT II, 600V CAT III)
 Measurement category IV is for measurement performed at the
source of low-voltage installation.
 Measurement category III is for measurement performed in the
building installation.
 Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.
 Measurement category I is for measurements performed on circuits
not directly connected to Mains.
Power supply
WARNING
 AC Input voltage: 100V/ 120V/ 230 V AC, 50/60Hz
 The power supply voltage should not fluctuate more
than 15%.
 Connect the protective grounding conductor of the
AC power cord to an earth ground, to avoid electrical
shock.
Fuse
WARNING
 Fuse type:
 100V/120V
 T0.1A 250V
 230V
 T0.08A 250V
 Make sure the correct type of fuse is installed before
power up.
 To avoid fire, only replace the fuse with the specified
type and rating.
 Disconnect the power cord before fuse replacement.
 Make sure the cause of a fuse blowout is fixed before
fuse replacement.
