DESCRIPTION

The AEMC® Instruments Models SR601 and 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 of up to 1000 ARMS continuous and are compatible with any AC ammeter, multimeter, or other current measurement instrument with an input impedance lower than 5 Ω. To achieve the stated accuracy, use the SR601/SR604 with an ammeter having an accuracy of 0.75 % or better.

WARNING:
Safety warnings are provided to ensure the safety of personnel and the proper operation of the instrument. Read the instructions 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 to the conductor

OPERATION

Please make sure that you have already read and fully understand the WARNING.

Making Measurements with the AC Current Probe Models SR601/SR604

• Connect the black lead of the current probe to the common and the red lead to the AC input on your DMM or other current measuring instrument. Select the appropriate current range (2 AAC range). Clamp the probe around the conductor to be tested with the arrow pointed toward the load. If the reading is less than 200 mA, select the lower range until you obtain the best resolution. Read the value displayed on the DMM and multiply it by the probe ratio (1000/1). (If reading = 0.659 A, the current flowing through the probe is 0.659 A x 1000 = 659 AAC)
• 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 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 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 errors in readings. To clean the probe jaws, use very fine sandpaper (fine 600) to avoid scratching the jaw, then gently clean with a soft oiled cloth.

REPAIR AND CALIBRATION

To ensure that your instrument meets factory specifications, we recommend that it be sent back to our factory Service Center at one-year intervals for recalibration or as required by other standards or internal procedures.

For instrument repair and calibration:
You must contact our Service Center for a Customer Service Authorization Number (CSA#). Send an email to repair@aemc.com requesting a CSA#, you will be provided a CSA Form and other required paperwork along with the next steps to complete the request. Then return the instrument along with the signed CSA Form. Please write the CSA# on the outside of the shipping container. If the instrument is returned for calibration, we need to know if you want a standard calibration or a calibration traceable to N.I.S.T.
