AC/DC Current Probe Model SL206

Warning

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

• C

onnect the probe to the o scilloscope or voltage m easuring

instrument before clamping the probe around a conductor.

• NEVER use the probe on circuits rated higher than 600V.

• NEVER leave the probe c la mped around a conductor whi le it

is not connected to a voltage measuring instrument or DMM.

• Carefully center the conductor inside the probe jaws and
ascertain that the probe is perpendicular to the conductor
before closing the jaws.

• AVOID, if possible, the proximity of other conduc tors which
may 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 has
defective leads.

Description

AC/DC Current Probe M odel SL2 06 meas ures low DC or AC fr om 10m A
to 80A
with digital multimeters, voltmeters, or other voltage-measuring
instruments. The probe jaws clamp around the conductor under test,
allowing current meas urements without breaking the circ uit. Hall sensor
technology senses the m agnetic f ield produc ed b y the current measur ed,
and generates a millivolt DC or AC output signal. The narrow jaw is
designed for optim um use in crowded wirin g in industrial an d automotive
environments.

Operation

Connection

Connect the current pro be to the m ultimet er or other i nstrum ent. 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 conduct or being measured. The “10mV/A” ra nge has an
output signal of 10mV/A AC/DC with an output of 500 millivolts
representing 50 amps present in the conductor being meas ured. Select
the multimeter range which best corresponds to the measured current.
For better reading stabilit y, 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 rem oved from the conductor, a small amount of
residual magnetism often remains in the core. This residual m agnetism
will cause the voltm et er to s ho w a small DC reading e ven tho ugh th er e 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 f unction in most m ultimeters is AC coupled . DC
offset caused by th e resi dual m agnet ism will co ntribut e to readin g er rors,
but can be minimized by using the zero adjust knob (see Figure 1) to
show a reading of ± a f ew counts on the multimeter (probe n ot 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.

AC/DC Current Probe Model SL206

Current Measurement

Select the appropriat e range on your multimeter. Zer o the probe in DC
and in DC coupled AC m easurements. Observe th e output polarities f or
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 d uring DC measurements, this sim ply 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 sh ock: do not att empt to perfor m any servic ing unless

you are qualified to do so.

• Avoid electrical shock and/or damage to the instrument: do not get
water or other foreign agents into the electronic module.

• Also see warning on page 2.

Cleaning

Be sure that matin g surfaces of the jaw ar e free of d irt or forei gn matter.
If they are rusted, ge ntly clean with a soft, lightly oiled cloth. Do n ot 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”. Unscre w the battery compartment screw and pu ll out the
battery compartm ent cover. Replace the battery and put the cover back
on. Do not replace the battery while probe is in use.

Repair and Calibrati on

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).
