Equus 3347 - DMM Inductive AMP Probe - Manual

The Current Clamp aids in measuring AC or DC current flow through
a wire or cable.
Safety Precautions
Do not operate this tool before reading these instructions in their
entirety. The following guidelines must be followed to avoid accidents
that can result in electric shock or personal injury.
■ Pay close attention to WARNING stamped on the tool’s case.
This warning, as well as all warnings and precautions used through
out these instructions, must be followed to avoid electric shock
and/or personal injury.
■ The RESPONSIBLE PARTY shall be made aware that, if the equip-
ment is used in a manner not specified by the manufacturer, the pro-
tection provided by the equipment may be impaired.
■ Before using this tool, verify its proper operation on a known similar
function source where the unit value is also known. Take corrective
action based on the indicated results.
To prevent electrical shock and/or damage to the tool or the equipment
under test, observe the following safety precautions:
■ DO NOT apply more than the rated voltage, as marked on the tool and
tester, between terminals or between any terminal and earth ground.
■ Use caution when working above 30V AC rms, 42 V peak, or 60 V
DC. Such voltages pose a shock hazard.
■ To avoid false readings that could lead to possible electric shock or
personal injury, replace the batteries as soon as the low battery indi-
cator lights.
■ Always inspect the test leads prior to every use. If any damage is
found, do not use the tool.
■ Always consider electrical and electronic equipment to be ener-
gized (live). Never assume any equipment is de-energized.
■ Never ground yourself when taking electrical measurements. Isolate
yourself from ground by using dry rubber insulating mats to cover all
exposed/grounded metal. Stand on rubber mats and wear dry clothing.
■ Use one hand, instead of two, whenever possible to take measure-
ments. If two hands must be used, use extreme caution not to con-
tact any energized conductors with your hands. Be certain test
leads are dry and clean.
■ Do not hold the tool beyond the hand grip when taking measure-
ments.
■ Don't become part of the circuit. Think safety. Act safely.
If working on a vehicle, take the following added precautions:
■ Only work on vehicle in a well ventilated area.
■ Always wear safety eye protection.
■ Avoid moving fan blades or any potentially moving parts.
■ Avoid hot engine parts.
■ Put transmission in "park" (automatic transmission vehicles) or
"neutral" (manual transmission vehicles). Set the parking brake.
■ Turn the ignition "off" before connecting or disconnecting any test-
ing equipment.
■ Put blocks on drive wheels.
■ Avoid wearing loose clothing or jewelry when working on a vehicle.
■ Read your vehicle's service manual and follow it's safety proce-
dures.

lead clipped together
Electrical [at 73±9 F (23±5 C) 70% relative humidity maximum]
■ Effective Measurement Range:
10mV/1A: 100mA to 20A DC or RMS AC for 200mV range of the
tester.
1mV/1A: 1A to 200A DC or RMS AC for 200mV range of the multi-
meter.
200A to 600A DC or RMS AC for 2V range of the multimeter.
■ Accuracy
System accuracy: Current clamp accuracy + tester accuracy
For example, if the measured conductor carries a 1A current, set
the Current Clamp to 1
0 mV/1A range to get an output signal of
10mV. Suppose the accuracy of the units is 1.5%, the tolerance
limit should be between 10.15mV maximum and 9.85mV mini-
mum.
When the unit is connected to a tester with an accuracy of 0.5% in
200mV range, the reading displayed on the tester will be 10.20mV
max. (10.15mV × (1+0.5%) = 10.20mV) and 9.80mV min.(9.85mV
× (1-0.5%) = 9.80mV)
■ Current Clamp Accuracy
DCA range = 1 0 mV/1A: ±(1.5%+50mA) 100mA~20A
DCA range = 1mV/1A: ±(2.0%+0.5A) 1A~200A; ±(2.5%+5A)
200A~600A
ACA range = 1 0 mV/1A: ±(2.0%+50mA) 100mA~20A
(40Hz~400Hz)
ACA range = 1mV/1A: ±(2.5%+0.5A) 1A~200A (40Hz~400Hz);
±(3.0%+5A) 200A~600A (40Hz~400Hz)
