Measurement
Chapter 2
Observe the following precautions to avoid
electric shock.
• Always verify the appropriate setting of the
function selector before connecting the
test leads.
• Disconnect the test leads from the mea-
surement object before switching the func-
tion selector.
• The maximum input voltage is 1000 VDC,
1000 V or 2×10
7
VHz. Attempting to mea-
sure voltage in excess of the maximum
input could destroy the instrument and
result in personal injury or death.
• The maximum input current is as follows;
A terminal: Continuous up to 10 A AC/DC.
µA.mA terminal: 1 A AC/DC
Never exceed this limit, as doing so could
result in destruction of the instrument and
personal injury or death.
• The maximum rated voltage between input
terminals and the ground is as follows;
CAT II : 1000 VDC, 1000 VAC
CAT III: 600 VDC, 600 VAC
Attempting to measure voltages exceeding
this level with respect to ground could
damage the instrument and result in per-
sonal injury.
• To avoid electrical shock, be careful to
avoid shorting live lines with the test leads.
• For safety, test lead connections must
always be made at the secondary side of a
circuit breaker.
