Amprobe ACDC-100 Clamp-On-Multimeters - Manual (Page 7)

6
Before and after hazardous voltage measurements, test the voltage function on a known •
source such as line voltage to determine proper meter functioning.
Keep your hands/fingers behind the hand/finger barriers (of the meter and the test leads)
•
that indicate the limits of safe access of the hand-held part during measurement.
inspect test leads, connectors, and probes for damaged insulation or exposed metal before
•
using the instrument. if any defects are found, replace them immediately.
This Clamp-on meter is designed to apply around or remove from uninsulated hazardous
•
live conductors. individual protective equipment must be used if hazardous live parts of
the installation could be accessible.
exercise extreme caution when: measuring voltage >20 V // current >10 mA // AC power
•
line with inductive loads // AC power line during electrical storms // current, when the fuse
blows in a circuit with open circuit voltage >1000 V // servicing CRT equipment.
Remove test leads before opening the case to change the battery.
•
Disconnect circuit power and discharge all high-voltage capacitors before testing •
resistance,continuity, diodes, or capacitance.
To avoid false readings, which could lead to possible electric shock or personal injury,
•
replace the batteries as soon as the low battery indicator (�) appears.

INTRoDUCTIoN
The ACDC-100 and ACDC-100 TRMS Clamp-on meters are 1000 Amp / 600 V clamp meters
with 50 mm jaw opening for industrial applications. The features include large conductor
size and in-rush current measurement along with AC / DC voltage, AC / DC current, Resistance,
Continuity and Diode Tests.
fEATURES
Alignment marks (see fig. 1)
place conductor within the jaws at the intersection of the indicated marks as close as possible
to maximize the accuracy of the reading.
MAX � / HoLD �
The holD feature freezes the display when the � button is pressed. The MAx feature
compares and displays the measured maximum value as fast as 30ms with auto-ranging
capability.
