AC Current Probe

Models SR601 and SR604

User Manual

DESCRIPTION: The SR601/SR604 (Cat. #2113.43/2113.44) are designed for use in industrial environments.

The ergonomic design allows them to easily attach to cables or small bus bars. The “circular” jaws guarantee

a very good accuracy and low phase shift. The probes have a measurement range up to 1000Arms

continuous and are compatible with any AC ammeter, multimeter, or other current measurement instrument

with an input impedance lower than 5Ω. To achieve the stated accuracy, use the SR601/SR604 with an

ammeter having an accuracy of 0.75% or better.

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.

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 is a type A current sensor. This symbol signifies that application around and removal from

HAZARDOUS LIVE conductors is permitted.

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.

OPERATION

Please make sure that you have already read and fully understand the WARNING section on page 1.

Making Measurements with the AC Current Probe Models SR601/SR604

•Connect the black lead of the current probe to “common” and the red lead to the AC current input on

your DMM or other current measuring instrument. Select the appropriate current range (2A AC range).

Clamp the probe around the conductor to be tested with the arrow pointed toward the load. If the reading

is less than 200mA, select the lower range until you obtain the best resolution. Read the value display on

the DMM and multiply it by the probe ratio (1000/1). (If reading = 0.659A, the current flowing through the

probe is 0.659A x 1000 = 659A AC)

•For best accuracy, avoid if possible, the proximity of other conductors which may create noise.

Tips for Making Precise Measurements

•When using a current probe with a meter, it is important to select the range that provides the best

resolution. Failure to do this may result in measurement errors.

•Make sure that probe jaw mating surfaces are free of dust and contamination. Contaminants cause air

gaps between the jaws, increasing the phase shift between primary and secondary. It is very critical for

power measurement.

MAINTENANCE

Warning:

•For maintenance use only original 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 not get water or other foreign agents into

the probe

Cleaning:

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. To clean the probe jaws, use very fine sand paper (fine 600)

to avoid scratching the jaw, then gently clean with a soft oiled cloth.

REPAIR AND CALIBRATION
