AC/DC Current Probe Model SL201

Description

AC/DC Current Probe Model SL201 measures low DC or AC from 50mA
to 150A

DC/120AAC. 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.

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 SL201 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 “1mV/A” range has an
output signal of 1mV/A AC/DC with an output of 50 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.

AC/DC Current Probe Model SL201

Zeroing the Probe

When the Current Probe Model SL201 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 0 ± 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 20mV 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 1mV/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.

Warning

• For maintenance use only specified replacement parts.

• Avoid electrical shock: do not attempt to perform any servicing unless

you are qu

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

Also see warning on page

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).
