2.3 Current Measurement
2.3 Current Measurement
• Never apply voltage to the test leads when
a current measurement function is
selected. Doing so may damage the prod-
uct and result in personal injury.
• To avoid electrical accidents, remove
power from the circuit before connecting
the test leads.
• To avoid electrical shock, do not use the
product to measure current in circuits of
600 V or greater. The current function
overload protection trips at 600 Vrms.
• Maximum input current in each range
40
μ
A/
μ
A/mA range: 420mADC/ 420 mA rms
10A range: 10 ADC/ 10 A rms
Do not input a current in excess of this
value. Otherwise, the measurement prod-
uct will be damaged, resulting in an acci-
dent that may cause injury or death.
Selecting the manual range:
Reselecting the auto range:
Press RANGE
("AUTO" is turned off)
Press RANGE (for at least 1 sec-
ond) ("AUTO" lights up)
Holding the measured
value:
HOLD AUTO Function,
page 25) or
HOLD Function, page 26)
Press H.AUTO/REL
→ Measure-
ment → Intermittent sound →
Move the test leads away from the
measurement object.
Press H.AUTO/REL
+Power-on →
Measurement →
Press H.AUTO/REL
Appearance of O.F: The measured value exceeds
1050 counts(10-A range) or 4200
counts (other ranges).
