Warning These safety warnings are provided to ensure the safety of personnel and proper operation of the instrument.

• Connect the probe to the oscilloscope or voltage measuringinstrument before clamping the probe around a conductor.
• NEVER use the probe on circuits rated higher than 600V.
• NEVER leave the probe clamped around a conductor while itis not connected to a voltage measuring instrument or DMM.
• Carefully center the conductor inside the probe jaws andascertain that the probe is perpendicular to the conductorbefore closing the jaws.
• AVOID, if possible, the proximity of other conductors whichmay create noise.
• Check the magnetic mating surfaces of the probe jaws;these should be free of dirt, rust, or other foreign matter.
• Do not use a probe that is cracked, damaged, or hasdefective leads.

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

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.

Packaging
The AC/DC Current Probe Model SL206 (Cat. #1201.45) is shipped with one 9V battery (not installed) and this user manual.

Compatibility
The AC/DC Current Probe Model SL206 is compatible with any DMM, voltmeter, or other voltage-measuring instrument that has the following features:

• Range and resolution capable of displaying 1mV of input.
• Voltmeter accuracy (uncertainty) of 0.75% or better to take full advantage of the accuracy of the probe.
• Minimum input impedance of 100kΩ (1V/A range) or 10kΩ (10mV/A range).

Description
AC/DC Current Probe Model SL206 measures low DC or AC from 10mA to 80ADC, 60AAC. This battery-powered clamp-on probe may be used with digital multimeters, voltmeters, or other voltage-measuring instruments. The probe jaws clamp around the conductor under test, allowing current measurements without breaking the circuit. Hall sensor technology senses the magnetic field produced by the current measured, and generates a millivolt DC or AC output signal. The narrow jaw is designed for optimum use in crowded wiring in industrial and automotive environments.

Operation

Connection
Connect the current probe to the multimeter or other instrument. Be sure to observe the polarities: red = positive terminal, black = common terminal. The Current Probe Model SL206 has a dual output, DC V output in DC and AC V output in AC. The “1V/A” range has an output signal of 1mV/mA AC/DC with an output of 2 volts representing 2 amps present in the conductor being measured. The “10mV/A” range has an output signal of 10mV/A AC/DC with an output of 500 millivolts representing 50 amps present in the conductor being measured. Select the multimeter range which best corresponds to the measured current. For better reading stability, you may use the DMM 2 Volt range and let the probe “warm-up”, for one minute before zeroing.

Zeroing the Probe
When the Current Probe Model SL206 has been used for a current measurement and then removed from the conductor, a small amount of residual magnetism often remains in the core. This residual magnetism will cause the voltmeter to show a small DC reading even though there is no current passing through the jaws of the probe. The residual magnetism should not cause a problem for AC current measurement because the AC voltage function in most multimeters is AC coupled. DC offset caused by the residual magnetism will contribute to reading errors, but can be minimized by using the zero adjust knob (see Figure 1) to show a reading of ± a few counts on the multimeter (probe not clamped on a conductor).
There will always be some instability and noise generated by the Hall sensor, the earth magnetic field and environmental noise. This is particularly noticeable on the most sensitive range 1V/A (1mV/mA) where you may have up to 5mV of uncertainty (see accuracy) which cannot be “zeroed out”. “Zero” the probe while it is connected to the DMM and on the range to be used. Let the probe “warm-up” for one minute before zeroing. Turn the zero adjust knob until the probe is zeroed.

Current Measurement
Select the appropriate range on your multimeter. Zero the probe in DC and in DC coupled AC measurements. Observe the output polarities for DC measurement. Clamp the probe on the conductor to be measured and read the current flowing directly on your meter. The output of the probe is 10mV/A AC/DC or 1mV/mA AC/DC. If your meter indicates a negative reading during DC measurements, this simply means that the current flow is in the opposite direction of the arrow marked “I” on the probe or that the probe connections are reversed (polarity). After measurement, turn the probe off.

Maintenance

Warning

• For maintenance use only specified replacement parts.
• Avoid electrical shock: do not attempt to perform any servicing unlessyou are qualified to do so.
• Avoid electrical shock and/or damage to the instrument: do not getwater or other foreign agents into the electronic module.
• Also see warning on page 2.

Cleaning
Be sure that mating surfaces of the jaw are free of dirt or foreign matter. If they are rusted, gently clean with a soft, lightly oiled cloth. Do not leave excessive oil residue.

Battery Replacement
When the probe is turned on, the green battery indication LED should light up. If not, replace the 9V battery (see Figure 1). To replace the battery, disconnect the probe from the circuit and the DMM. Turn the probe “OFF”. Unscrew the battery compartment screw and pull out the battery compartment cover. Replace the battery and put the cover back on. Do not replace the battery while probe is in use.

Repair and Calibration
To ensure that your instrument meets factory specifications, we recommend that it be submitted 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#). This will ensure that when your instrument arrives, it will be tracked and processed promptly. 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. (includes calibration certificate plus recorded calibration data).
