Any transport damage due to faulty packaging will be excluded from
warranty claims.
• In order to avoid instrument damage, it is advised to remove batteries
when not using the instrument over a certain time period. However,
shouldtheinstrumentbecontaminatedbyleakingbatterycells,youare
kindly requested to return it to the factory for cleaning and inspection.
• Instruments must be stored in dry and closed areas. In the case of an
instrument being transported in extreme temperatures, a recovery
time of minimum 2 hours is required prior to instrument operation.
Safety

• The Amprobe Current Clamp AC50A has been manufactured and
tested to comply with the safety regulations for electronic measuring
equipment contained in IEC61010 and EN 61010, and left the factory
in a safe condition. To maintain this condition, the user must observe
the safety instructions contained in this users manual.
• To avoid electric shock, safety measures must be observed when working
with voltages higher than 60V DC or 30 V RMS (42.4 V peak).
• Before each measurement make sure that the test leads and the
instrument are undamaged.
• Only handle test leads and probes on the grips provided. Avoid
touching probes under any circumstances.
• Measurements in dangerous proximity of electrical installations are
only to be executed when instructed by a responsible electrical
specialist, and never alone.
• The relevant safety regulations for electrical plant and equipment
must be observed during all operations.
• The instrument must only be used in the specified ranges.
• Before opening the instrument, it must be disconnected from all circuits.
• Protect the instrument from prolonged exposure to direct sunlight.

Appropriate Usage
• The instrument may only be used under the conditions and purposes
for which it was conceived. For this reason, in particular the safety
references, the technical data including environmental conditions and
the usage in dry environments must be followed.
• If the instrument is modified in any way, operational safety is no
longer ensured.
• Theinstrumentmayonlybe openedbyanauthorisedservicetechnician,
e.g. for fuse replacement.

Operation
Preparation and safety measures
Installing the battery
Before using the instrument, the battery must be installed. This is carried
out as follows:
1) Separate the instrument from any circuit, and remove the test leads.
2) Open the housing by removing the screw on the rear face.
3) Fit the new batteries (2 type 1.5 V IEC LR6), taking care that the polarity
is correct. Make sure that no wires are trapped between the 2 halves
of the housing and close.
4) The instrument is now ready for use.
• The selector switch must be turned to the desired type of measurement
before the probes are connected to the unit under test (UUT).
• Before switching to a new function, the probes must always be removed
from the UUT.
• Usetheinstrumentonlyincleananddrysurroundings.Dirtandmoisture
reduce the effectiveness of the insulation, with consequent danger of
electric shock, especially when dealing with high voltages.
• Use the instrument only in the specified ranges. Before making
measurements, verify that the instrument is functioning properly, for
example by testing on a known voltage or current. Make sure that the
test leads are undamaged.

Current Measurements
If tangible dangerous active parts are present in the plant where you
are making measurements, individual protection equipment (e.g.
suitable covers) must be used.
Always hold the instrument below the handle shroud.
The respective accident prevention regulations established by the
professional associations are to be strictly enforced at all times regarding
tasks executed under voltage or in proximity of parts under voltage.
1) Turn selector switch (2) to the AC current range you need
2) Open the clamp, and close it round the conductor. Make sure that the
clamp properly encircles the conductor, and that there is no air gap
between the jaws. For best measurement results and highest accuracy,
have the conductor placed in center of clamp jaws.

For incorrect measurement, the display equals zero. In compliance with
the Kirchhoff’s current law states the sum of all currents equals zero.
However, this measurement layout in conjunction with a very sensitive
current clamp can be used to measure leakage currents.

MIN/MAX and peak values/ Auto Power Off
The MIN/MAX button can be used to find the largest and the smallest value
of a series of measurements. Press the button to toggle between MAX and
MIN values. Press and hold the button for 2 seconds to exit this function. The
MAX/MIN is not available in the Continuity and Hz function.
Pressing it a second time changes to MAX mode, for the largest value.
Pressing the button a third time returns the instrument to normal
operation.

Maintenance
Provided it is used in accordance with the user manual, the instrument
needs no special maintenance.
Cleaning
If the instrument is dirty after daily usage, clean it by using a humid cloth
and a mild household detergent.
Prior to cleaning, ensure that instrument is switched off and dis-
connected from external voltage supply and any other instruments
connected (such as UUT, control instruments, etc.).
Never use acid detergents or dissolvents for cleaning.
Changing the battery
Prior to storage battery replacement, disconnect the instrument
from any circuits.
Only use batteries as described in the technical data section.
• If the symbol for Low-battery appears in the upper left corner of the
display, the battery must be changed.
This is carried out as follows:
1) Separate the Amprobe Current Clamp AC50A from any circuit, and
remove the test leads.
2) Switch the instrument off.
3) Open the housing by removing the 3 screws on the rear face.
4) Remove the old batteries.
5) Fit the new batteries (2 type 1.5 V IEC LR6), taking care that the polarity
is correct. Make sure that no wires are trapped between the 2 halves
of the housing, and close it again.
6) The instrument is now ready for further use.
Please consider your environment when you dispose of your one-way
batteries or accumulators. They belong in a rubbish dump for hazardous
waste. In most cases, the batteries can be returned to their point of sale.
Please,complywiththerespectivevalidregulationregardingthereturn,
recycling and disposal of used batteries and accumulators.
If an instrument is not used over an extended time period, the batteries
must be removed. Should the instrument be contaminated by leaking
battery cells, the instrument has to be returned for cleaning and inspec-
tion to the factory.
Calibration Interval
We suggest a calibration interval of one year. If the instrument is used
very often or if it is used under rough conditions we recommend shorter
intervals. If the instrument is used only a few times a year, the calibration
interval can be extended to 3 years.
