Connecting the measurement lines
Please read "Handling the Instrument" (p.6) carefully before connecting the instru-
ment to the measurement lines.
Connect cables to the instrument’s voltage and current input terminals.
You will need: A Phillips head screwdriver with a No. 3 tip
• Verify that power to the measurement lines has been cut off before connecting the
instrument to them.
• To avoid electric shock or a short-circuit at the input terminals, use solderless termi-
nals that cover wiring with insulation.
• To prevent instrument damage or electric shock, use only the screws (M6
×
12 mm)
for securing the voltage input terminals and current input terminals in place and the
screws (M3
×
6 mm) for securing the safety cover in place that shipped with the prod-
uct. If you loose any screw or find that any screws are damaged, please contact your
Hioki distributor for a replacement.
Safety covers
• The safety covers play a protective role by preventing contact with the terminals. Always attach the covers
before using the instrument.
• Verify that no voltage is being applied to the measurement lines before attaching or removing the safety
covers.
