Warning
To prevent possible electrical shock, fire, or personal injury:
•
Hold the Product behind the tactile barrier.
•
Do not measure current while the test leads are in the input jacks.
Hazardous Voltage Indicator
When the Clamp senses a voltage more than
±
30 V or a voltage overload (OL),
Z
shows on the
display to tell you a hazardous voltage is at the Clamp input.
AC Voltage Measurement with Test Leads
To measure ac voltage and the frequency:
1. Turn control knob to
V
.
2. Connect the black test lead to the
COM
terminal and the red test lead to the
V
X
terminal.
3. Touch the probes to the test points of the circuit.
The display shows the ac voltage and the frequency.
DC Voltage Measurement with Test Leads
To measure dc voltage:
1. Turn control knob to
N
.
2. Connect the black test lead to the
COM
terminal and the red test lead to the
V
X
terminal.
3. Touch the probes to the test points of the circuit.
The display shows the measurement.
4. Push
to toggle on/toggle off the mV function shown in yellow at the control knob
position.
The Clamp checks the polarity during a dc voltage measurement. When dc voltage is less than
-10 V:
1. Red LEDs blink and continue for 10 s.
2. Beeper sounds and continues for 10 s.
3.
P
blinks on the display.
