1. INTRODUCTION
Thank you for purchasing an AEMC® Instruments DC/AC Microprobe K100/
K110.
For the best results from your instrument and for your safety, you must
read the enclosed operating instructions carefully and comply with the
precautions for use. Only qualied and trained operators should use this
product.
Symbols and Denitions
Signies that the instrument is protected by double or reinforced insulation
CAUTION - Risk of Danger! Indicates a WARNING. Whenever this symbol
is present, the operator must refer to the user manual before operation
Indicates a risk of electric shock. The voltage at the parts marked with this
symbol may be dangerous
This product complies with the Low Voltage & Electromagnetic Compatibility
European directives (73/23/CEE & 89/336/CEE)
Denition of Measurement Categories (CAT)
CAT IV corresponds to measurements performed at the primary electrical
supply (< 1000 V).
Example: primary overcurrent protection devices, ripple control units, and
meters.
CAT III corresponds to measurements performed in the building installa-
tion at the distribution level.
Example: hardwired equipment in xed installation and circuit breakers.
CAT II corresponds to measurements performed on circuits directly con-
nected to the electrical distribution system.
Example: measurements on household appliances and portable tools.

1.1 PRECAUTIONS FOR USE
These safety warnings are provided to ensure the safety of personnel and
proper operation of the instrument.
• Read the instruction manual completely and follow all the safety
information before attempting to use or service this instrument.
• Use caution on any circuit: Potentially high voltages and currents may
be present and may pose a shock hazard.
• Read the Safety Specications section prior to using the Model K100/
K110. Never exceed the maximum voltage ratings given.
• Safety is the responsibility of the operator.
• NEVER open the back of the instrument while connected to any circuit
or input.
• ALWAYS connect the Model K100/K110 adapter to the display device
before clamping the probe onto the sample under test.
• ALWAYS inspect the instrument, probe, probe cable and output
terminals prior to use. Replace any defective parts immediately.
• NEVER use the Model K100/K110 on electrical conductors rated above
300V CAT II, EN61010-1.
1.2 RECEIVING YOUR SHIPMENT
Upon receiving your shipment, make sure that the contents are consistent
with the packing list. Notify your distributor of any missing items. If the
equipment appears to be damaged, le a claim immediately with the car-
rier and notify your distributor at once, giving a detailed description of any
damage.

2. PRODUCT FEATURES
2.1 DESCRIPTION
Model K100 and Model K110 are low current measurement instruments
that feature a compact, high sensitivity current probe. Unlike other instru-
ments, the Model K100 exhibits a wide dynamic operating range, which
extends from below 100µA to ± 4.5A peak, from DC to 2.0kHz*, without the
need for ranging. The K110 has an operating range of 100µA to ± 450mA
Peak, from DC to 1500Hz.*
Models K100 and K110 are designed to be operated in conjunction with a
digital multimeter, oscilloscope or recording device. The MicroProbe out-
puts the current measured in the form of a voltage that is the image of the
current, in shape and amplitude. The Model K100 outputs 1mV per mA of
measured current. The Model K110 outputs 10mV per mA of measured
current. To take advantage of the Model K100 high sensitivity, best results
are obtained through 4-1/2 digit (or more) DMM with a relative zero func-
tion. The Model K110 was designed to provide the operator with enhanced
low current linearity and accuracy, but is limited to 450mA Peak current.
The Model K100/K110 always outputs a signal proportional to the total
current (AC+DC) in the conductor under test. This has proven to be the
most versatile signal output format, and allows the user to isolate and
measure DC and AC components of measured current separately, if so
desired. Typical applications include 4 to 20mA loop measurements, auto-
motive current applications, benchtop electronic current consumption in
circuits, and other applications requiring very low current measurements
in crowded areas.
