INTRODUCTION

WARNING

The safety warnings are provided to ensure the safety of personnel and proper operation of the instrument. Read the instruction completely

• Use caution on any circuit: potentially high voltages and currents may be present and may pose a shock hazard.
• Do not use the probe if damaged. Always connect the current probe to the measuring device before it is connected around the conductor
• Do not use on non insulated conductor with a potential to ground greater than 600V CAT III pollution 2. Use extreme caution when clamping around bare conductors or bus bars.
• Before each use, inspect the probe; look for cracks in housing or output cable insulation.
• Do not use clamp in wet environment or in locations that hazardous gases exist.
• Do not use the probe anywhere beyond the tactile barrier.

Definition of Measurement Categories

CAT II: For measurements performed on circuits directly connected to the electrical distribution system. Examples are measurements on household appliances or portable tools.

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 IV: For measurements performed at the primary electrical supply (<1000V) such as on primary overcurrent protection devices, ripple control units, or meters.

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, file a claim immediately with the carrier and notify your distributor at once, giving a detailed description of any damage. Save the damaged packing container to substantiate your claim.

Accessories and Replacement Parts
Male Banana – Female BNC Adaptor (XF-SS): Cat. #2111.32

PRODUCT FEATURES

The AC Current Oscilloscope Probe Model SR661 expands oscilloscope applications in industrial or power environments, and is ideal for analysis and measurement of distorted current waveforms and harmonics.

The Model SR661 permits accurate display and measurement of currents from 100mA to 1000Arms, 1Hz to 100kHz (with current derating) without breaking into the circuit. A passive filter eliminates noise, ring on rapid rising (di/dt) waveforms, and ensures accurate screen displays.

The probe connects directly to an oscilloscope through an insulated coaxial cable with an insulated BNC.

Compatibility

The Model SR661 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 0.2 to 0.5V per division, or 2V range
• Minimum input impedance of 1MΩ

Features

1. Jaw opening of 2.25″
2. Maximum dimension of conduct is 2.13″ (54mm)
3. Tactical Barrier. Always keep hands below this barrier at all times.
4. Arrow indicates direction of current flow. Current flows in a positive direction when it travels from supply to load.
5. Three position switch
6. 6.5 ft (2m) output cable

OPERATION

Current Measurement

WARNING: Always connect the probe to the instrument before clamping onto the circuit under test.

• Connect the Model SR661 to the proper input channel on the oscilloscope.
• Begin with the least sensitive range on the current probe (1mV/A)
• Select the 0.5V/Division range on the oscilloscope.
• Clamp the probe on the conductor to be measured and read the current flowing directly on your oscilloscope.

(Remember to unclamp the probe from the conductor before disconnecting it from your meter or instrument.)

You may also use your oscilloscope to amplify the signal while using the 1mV/A probe range (which offers the best accuracy and least phase shift).

NOTE: It is possible to change the range on the current probe without removing the probe from the current carrying conductor, but it is important to remember not to exceed the permissible peak ratings of 2000mV peak or 4000 mV peak to peak maximum. The peak ratings by range are: 20A peak @ 100mV/A, 200A peak @ 10mV/A and 2000A peak @ 1mV/A.

MAINTENANCE

WARNING

• To ensure optimum performance, it is important to keep the probe jaw mating surfaces clean at all times. Failure to do so may result in error in readings.
• For maintenance use only specified factory replacement parts.
• To avoid electrical shock, do not attempt to perform any servicing unless you are qualified to do so.
• To avoid electrical shock and/or damage to the instrument, do notallow water or other foreign substances into the case.
• Disconnect the unit from all circuits and test cables before opening the case.
• Use caution with metallic tools that may short battery packs, power supplies, etc.

Cleaning

• To clean the probe body, use a soft cloth dampened in a solutionof mild detergent and water. To clean the core, open the jaw and clean the exposed core surfaces with a cotton swab dampened with isopropyl alcohol (isopropanol) or ethyl alcohol (fotocol or ethanol). Lubricate the jaws mating surfaces with a light oil.
• Do not use chemicals containing benzine, benzene, toluene, xylene, acetone, or similar solvents.
• Do not immerse the probe in liquids or use abrasive cleaners.
