Basic Measurements
XW 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.
Note
Exposure to severe mechanical shock may cause the
readings of the Product to not meet the specifications.
If the published accuracy is required, the Product
should be calibrated to verify proper operation after
such an event.
Hazardous Voltage Indicator
When the Clamp senses a voltage ±30 V or a voltage overload
(OL),
Z shows on the display to tell you a hazardous voltage is at
the Clamp input.
FieldSense™ Measurement
FieldSense measurement, or non-contact voltage (NCV)
measurement, is ac voltage, current, and frequency measurement
with no electrical contact to live voltage. The Clamp display shows
the voltage and current measurements at the same time.
Note
All FieldSense measurements require a ground lead
connection.
FieldSense AC Current, Voltage, and Frequency
To make the measurement:
1. Insert the ground lead into the COM input and attach the
alligator clip to ground.
2. Rotate the control knob to U.
The display shows the
U icon.
3. Use the jaw release to open the jaw and position the Clamp
around the conductor. Close the jaw and make sure the wire
position is correct. See Figure 2.
Figure 2. Wire Placement
The display shows
C to indicate that the measurement is
from the jaw. When the current measurement is <0.5 A, the
center dot in the icon flashes. For current measurements
>0.5 A, the center dot in the icon is steady. The Aac display
shows
- - - when a measurement is <1 A.
Note
Use
B to toggle on/toggle off the Amps Hz function
shown in yellow at the control knob position.
FieldSense technology is not intended to measure the
output of a variable-frequency drive (VFD) motor
controller. Use the
V or Kcontrol knob position for
this application.
