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 un-insulated
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.

CAUtIoN
for non-invasive ACA current measurements, clamp the jaws around only one single
conductor of a circuit for load current measurement. More than 1 conductor will cause
false readings.
UNPACkINg AND CoNtENtS
Your shipping carton should include
1 ACD-31P or ACD-41PQ
1 Test lead set
1 Type K Thermocouple probe
2 AAA - 1.5V Batteries
1 Users Manual
1 Carrying Case
if any of the items are damaged or missing, immediately return the complete package to
the place of purchase for an exchange.
INtRoDUCtIoN
The ACD-31P and ACD-41PQ are True RMS responding, autoranging, 400 Amp / 600 V
Clamp-on power quality meters. The features include AC / DC voltage, AC / DC current,
Resistance, Continuity and Power Quality measurements.
oPERAtIoN
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.
