Operation

The 1146B AC/DC Current Oscilloscope Probe expands oscilloscope

applications in industrial, automotive or power environments, and

is ideal for analysis and measurement of distorted current

waveforms and harmonics. The probe permits accurate display and

measurement of currents from 100 mA to 100A rms, DC to 100 kHz

without breaking into the circuit. The probe uses Hall effect

technology to measure AC and DC signals. The probe connects

directly to an oscilloscope through a 2 meter coaxial cable with an

insulated BNC.

The 1146B probe is compatible with any analog or digital

oscilloscope or other voltage measuring instrument which has the

following features:

■BNC input connector.

■Range capable of displaying 0.2V to 0.5V per division.

■Minimum input impedance of 1 MΩ.

Before Using the Probe

■Install the battery that was shipped with the probe. Refer to “To

Install the Battery” on page 6.

■Read the warnings listed under “Safety” on page 8.

■Confirm that the probe has not been damaged in transit. If the

unit is damaged, or fails to operate according to the

specifications, contact your dealer or Agilent representative.

■Check that the contents of the shipment agree with the packing

slip. If anything is missing, contact your nearest Agilent

Technologies Sales Office. If the shipment was damaged, contact

the carrier, then contact the nearest Agilent Technologies Sales

Office.

Operation

Figure 1 Control and Connector Identification

Zero-Adjust Knob. Use the zero adjust knob to eliminate the probe’s

offset before performing a measurement.

Battery Power Indicator. To ensure proper readings with your

current probe, be sure that the green battery indicator is lit during

measurement. If not, replace the 9V battery as described in “To

Install the Battery” on page 6.

Peak Overload (OL) Indicator. If the red Peak Overload indicator

illuminates during measurement, this indicates that the peak value

exceeds the instrument response level and that the output is

distorted. Use the range selection switch to change the probe to a

higher range, if possible.

Range Selection Switch. Use the range selection switch to turn the

probe OFF and to select from two ranges: 10 mV/A and 100 mV/A.

WARNING It is possible to change the current probe ‘s range without removing the probe

from the current carrying conductor, but never exceed the permissible peak

ratings of 1000 mV peak or 2000 mV peak-to-peak maximum. The peak ratings

by range are: 10A peak on the 100 mV/A range, 100A peak on the 10 mV/A

range.

Operation

To Install the Battery

Before using the probe for the first time, you must install the

battery. When the probe is turned on, the green battery indication

LED should light up. If not, replace the battery.

1Disconnect the probe from the circuit and the oscilloscope.

WARNING Do not replace the battery while probe is in use.

2Set the probe’s switch to the OFF position.

3Unscrew the battery compartment screw (shown on Figure 1 on

page 5) and pull out the battery compartment cover.

4Install the new 9V battery and put the cover back on.

To Perform a Current Measurement

1Read the warnings in “Safety” on page 8.

2Connect the current probe to an input channel on the oscilloscope.

WARNING Connect the probe to the oscilloscope or voltage measuring instrument before

clamping the probe around a conductor.

3Set the current probe to its least sensitive range (10 mV/A).

4Select the 0.5 V/division range on the oscilloscope.

5Clamp the probe on the conductor to be measured and read the

current flowing directly on your oscilloscope.

You may also use your oscilloscope to amplify the signal while

using the 100 mV/A probe range (which offers the best accuracy

and least phase shift).

WARNING It is possible to change the range on the current probe without removing the

probe from the current carrying conductor, but never exceed the permissible

peak ratings of 1000 mV peak or 2000 mV peak-to-peak maximum. The peak

ratings by range are: 10A peak on the 100 mV/A range, 100A peak on the

10 mV/A range.

Product Markings

To Clean the Probe

1Remove the probe from any circuit under test and from the

oscilloscope.

2Clean the external surfaces of the probe with a soft cloth

dampened with a mixture of mild detergent and water.

3Clean the mating surfaces of the probe’s jaws so that they are free

of dirt or foreign matter. If rust is present, gently clean the mating

surfaces with a soft cloth that has been lightly oiled with standard

machine oil. Do not leave excessive oil residue.

WARNING Make sure that the probe is completely dry before reconnecting it to a power

source.

Safety

This manual provides information and warnings essential for

operating this probe in a safe manner and for maintaining it in safe

operating condition. Before using this equipment and to ensure safe

operation and to obtain maximum performance from the probe,

carefully read and observe the following warnings, cautions, and

notes.

This apparatus has been designed and tested in accordance with

IEC61010, Safety Requirements for Measuring Apparatus, and has

been supplied in a safe condition. Note the external markings on

the instrument that are described in this document.

WARNING Connect the probe to the oscilloscope or voltage measuring instrument before

clamping the probe around a conductor.

WARNING Never use the probe on circuits rated higher than 600 Vac RMS CAT II or 300 Vac

RMS CAT III or with float voltage greater than 600 V.

WARNING Never leave the probe clamped around a conductor while it is not connected to

an oscilloscope or voltage measuring instrument.

WARNING Carefully center the conductor inside the probe jaws and ascertain that the

probe is perpendicular to the conductor before closing the jaws.

WARNING Check the magnetic mating surfaces of the probe jaws; these should be free of

dirt, rust, or other foreign matter

WARNING Do not use a probe which is cracked, damaged or has defective leads.

WARNING Avoid, if possible, the proximity of other conductors which may create noise.

WARNING Do not install substitute parts or perform any unauthorized modification to the

probe.

WARNING Do not clamp the probe on a bare/un-insulated conductor.

Safety

WARNING Do not operate the probe or oscilloscope in the presence of flammable gasses or

fumes. Operation of any electrical instrument in such an environment

constitutes a definite safety hazard.

WARNING Do not use the probe or oscilloscope in a manner not specified by the

manufacturer.

WARNING Service instructions are for trained service personnel. To avoid dangerous

electric shock, do not perform any service unless qualified to do so. Do not

attempt internal service or adjustment unless another person, capable of

rendering first aid and resuscitation, is present.

Concerning the Oscilloscope or Voltage Measuring

Instrument to Which the Probe is Connected

WARNING Whenever it is likely that the ground protection is impaired, you must make the

instrument inoperative and secure it against any unintended operation.

WARNING If you energize the instrument by an auto transformer (for voltage reduction or

mains isolation), the ground pin of the input connector terminal must be

connected to the earth terminal of the power source.

WARNING Before turning on the instrument, you must connect the protective earth terminal

of the instrument to the protective conductor of the (mains) power cord. The

mains plug shall only be inserted in a socket outlet provided with a protective

earth contact. You must not negate the protective action by using an extension

cord (power cable) without a protective conductor (grounding). Grounding one

conductor of a two-conductor outlet is not sufficient protection.

WARNING Only fuses with the required rated current, voltage, and specified type (normal

blow, time delay, etc.) should be used. Do not use repaired fuses or

short-circuited fuseholders. To do so could cause a shock or fire hazard.

WARNING Capacitors inside the instrument may retain a charge even if the instrument is

disconnected from its source of supply.
