Warning
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.
• Wear protective clothing and gloves as required.
• Use caution on any circuit: potentially high voltages and
currents may be present and may pose a shock hazard.
• Read the safety specifications section prior to using the current probe. Never exceed the max voltage ratings given.
• Safety is the responsibility of the operator. The AmpFlex must be used only by qualified personnel using applicable safety precautions.
®
• ALWAYS de-energize the circuit before wrapping the AmpFlex
®
around bare conductors, bus bars, or near live
parts. Do not wrap on live conductors.
• ALWAYS connect the electronic module to the display device before wrapping the AmpFlex
®
around the sample
being tested.
• ALWAYS inspect the module, sensor, sensor cable, and output terminals prior to use. Replace any defective parts immediately. Use only factory parts.
®
• NEVER use the AmpFlex
on electrical conductors rated
above 600V CAT IV; 1000V CAT III.

International Electrical Symbols

This symbol signifies that the current probe is protected by double or reinforced insulation. Use only factory specified replacement parts when servicing the instrument.
This symbol signifies CAUTION! and requests that the user refer to the user manual before using the instrument.
This symbol refers to a type B current sensor. Do not apply around or remove from HAZARDOUS LIVE conductors without additional protective means (de-energizing the circuit or wearing protective clothing suitable for high voltage work).

Definition of Measurement Categories

CAT IV: For measurements performed at the primary electrical supply
(<1000V) such as on primary overcurrent protection devices, ripple control units, or meters.
CAT III: For measurements performed in the building installation at the
distribution level such as on hardwired equipment in fixed installation and circuit breakers.
CAT II: For measurements performed on circuits directly connected to
the electrical distribution system. Examples are measurements on household appliances or portable tools.

AmpFlex® - Flexible AC Current Probes

Description

The AmpFlex® is a flexible AC current transformer composed of a flexible sensor and an electronic module. The flexible sensor permits measurements on conductors where standard clamp-on probes could not be used. In particular, it can be installed in tight spaces, around breaker panels, around cable bundles, around wide or large bus bars, or even wrapped around irregular shapes. The Shape Memory feature enables the user to “pre-shape” the sensor before inserting it between or around conductors. This feature facilitates closing, enhances user safety, and alleviates the drooping effect typically associated with flexible sensors.
®
The AmpFlex standard transformers. The transformation principle is based on an air core. It presents virtually no load to the system under test, has a low phase shift and excellent frequency response, and cannot be damaged by overloads.
The sensor assembly is waterproof and insulated for 600V CAT IV; 1000V CAT III. The AmpFlex designed with materials and components to meet international agency approvals.
The AmpFlex for direct readings on DMMs, data loggers, oscilloscopes, and power or harmonic meters. TRMS measurements are taken when connected to a TRMS meter. The AmpFlex AC component of the measured signal is measured.
The length of the flexible sensor can be selected in lengths of 24", 36", and 48" in length. Consult the factory for custom lengths, ranges and/or features.

Instrument Compatibility

The AmpFlex® is compatible with any multimeter, AC voltmeter, or other voltage measuring instrument with an input impedance greater than 1MΩ. To achieve the best overall accuracy, use the AmpFlex
®
with a AC voltmeter having an accuracy of 0.75% or better.

Operation

Please make sure that you have already read and fully understand the WARNING section on page 2.

Making Measurements with the AmpFlex®:

• Connect the electronic module to the AC Volt range of your DMM or measuring instrument. Select the appropriate module output voltage range. If the current magnitude is unknown, and if AmpFlex ranges, select the lowest mV/A output setting.
• Wrap the flexible core around the conductor to be tested. If possible within range, select the higher mV/A AmpFlex
®
output range to obtain the best resolution. Do not exceed specified current range for the output. Do not use on selected range if overload LED goes on.
• Read the displayed value on the DMM and divide it by the range selected (i.e. if reading = 2.59V with the 10mV/A output range, the current flowing through the probe is 2590mV ÷ 10 = 259A).
• For best accuracy, carefully center the conductor inside the flexible core, and avoid if possible, the proximity of other conductors which may create noise and interference (particularly near the latch).
• True RMS measurements are obtained when the AmpFlex connected to a True RMS meter. Note that the DC component is not measured.

Tips for Making Precise Measurements:

• When using the AmpFlex® with a meter, it is important to select the range that provides the best resolution. Failure to do this may result in measurement errors.
®
• For best results, select the highest AmpFlex and the most sensitive meter range for this output.
• Make sure the DMM or measuring instrument can accurately measure
AC. Certain inexpensive DMM have poor resolution and accuracy
mV when measuring low mV AC.
• For best accuracy, center the AmpFlex

Tips for Making Precise Measurements (continued):
• To increase the sensitivity or measure on low currents, the AmpFlex® may be wrapped several times around the conductor. Remember to
divide your reading by the number of turns for the actual measurement (see Figure 4).
• The overall measurement accuracy is the sum of the AmpFlex accuracy and the displaying instrument accuracy.

Maintenance

Warning

• For maintenance use only specified replacement parts.
• To avoid electrical shock, do not attempt to perform any servicing
unless you are qualified to do so.
®
• Do not perform any service while the AmpFlex
• To avoid electrical shock and/or damage to the instrument, do not get
water or other foreign agents into the electronic module.
• Also see warning on page 2.

Battery Replacement

• If the power ON indicator (green LED) blinks or does not light up, replace the battery.
®
• Remove the AmpFlex
• To replace the battery, open rear case, replace battery and
reassemble. The green LED should go on when the module is turned on.
from any circuit before replacing the battery.

Cleaning

• It is important to keep the probe sensor latch mating surfaces clean and prevent foreign bodies from hampering the closing. The sensor may be gently cleaned with a soft cloth, soap and water. Dry immediately after cleaning. Avoid water penetration into the electronic module.
• Make sure the sensor, electronic module, and all leads are dry before any further use.
