LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship
under normal use and service. The warranty period is one year and begins on the date of
shipment. Parts, product repairs, and services are warranted for 90 days. This warranty
extends only to the original buyer or end-user customer of a Fluke authorized reseller,
and does not apply to fuses, disposable batteries, or to any product which, in Fluke's
opinion, has been misused, altered, neglected, contaminated, or damaged by accident or
abnormal conditions of operation or handling. Fluke warrants that software will operate
substantially in accordance with its functional specifications for 90 days and that it has
been properly recorded on non-defective media. Fluke does not warrant that software will
be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-
user customers only but have no authority to extend a greater or different warranty on
behalf of Fluke. Warranty support is available only if product is purchased through a Fluke
authorized sales outlet or Buyer has paid the applicable international price. Fluke re-
serves the right to invoice Buyer for importation costs of repair/replacement parts when
product purchased in one country is submitted for repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price,
free of charge repair, or replacement of a defective product which is returned to a Fluke
authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center to obtain
return authorization information, then send the product to that service center, with a de-
scription of the difficulty, postage and insurance prepaid (FOB Destination). Fluke as-
sumes no risk for damage in transit. Following warranty repair, the product will be re-
turned to Buyer, transportation prepaid (FOB Destination). If Fluke determines that failure
was caused by neglect, misuse, contamination, alteration, accident, or abnormal condition
of operation or handling, including overvoltage failures caused by use outside the prod-
uct’s specified rating, or normal wear and tear of mechanical components, Fluke will pro-
vide an estimate of repair costs and obtain authorization before commencing the work.
Following repair, the product will be returned to the Buyer transportation prepaid and the
Buyer will be billed for the repair and return transportation charges (FOB Shipping Point).
THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF
ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED
TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PAR-
TICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT,
INCIDENTAL, OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF
DATA, ARISING FROM ANY CAUSE OR THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty,
or exclusion or limitation of incidental or consequential damages, the limitations and ex-
clusions of this warranty may not apply to every buyer. If any provision of this Warranty is
held invalid or unenforceable by a court or other decision-maker of competent jurisdiction,
such holding will not affect the validity or enforceability of any other provision.

i50s Current Probe/
PSi50s Power Supply
Introduction
XWWarning
To avoid electrical shock or possible injury, do not use the
i50s Current Probe with oscilloscopes with floating inputs,
i.e. oscilloscopes not referenced to ground.
The i50s Current Probe (“the Probe”) has been designed for use with
oscilloscopes for accurate, non-intrusive measurement of ac, dc and complex
waveform currents. Using advanced Hall Effect technology the Probe can
accurately measure currents over the frequency range of dc to 50 MHz with a
measuring range up to 50 A peak. The Probe is a general purpose, universal
current Probe which can be used with any oscilloscope.
XWWarning
To avoid electrical shock or possible injury, use the PSi50s
Power Supply only with i50s Current Probes.
The PSi50s Power Supply (the “Power Supply”) is an external power supply
that can simultaneously power two i50s Current Probes. The Power Supply is
supplied from single-phase mains 115 or 230 V ac, with frequencies from 44
to 60 Hz, and provides a symmetrical dc voltage of ±12 V.

Safety Instructions
Please read this section carefully. It will make you familiar with the most
important safety instructions for handling your product. In this manual, a
Warning identifies conditions and actions that pose hazard(s) to the user. A
Caution identifies conditions and actions that may damage the Probe, Power
Supply, or the test instruments.
WX Warning
The Probe and Power Supply may only be used and
handled by qualified personnel. To avoid electrical shock
or personal injury, follow these precautions:
•Use caution during installation and use of these
products; high voltages and currents may be present
in circuits under test.
•Do not use the Probe or Power Supply if damaged.
Always connect the Probe to display device before it is
installed around the conductor.
•If the Probe or Power Supply is not used in a manner
specified by the manual, the protection provided may
be impaired.
•Use the Power Supply only with i50s Current Probes.
•Do not use the Probe without consulting local and
national safety codes and use of protection equipment
is recommended.
•Do not hold the Probe beyond the tactile barrier (see
Figure 1).
•Before each use, inspect the Probe and Power Supply.
Look for cracks or missing portions of the housing or
output cable insulation. Also look for loose or
weakened components. Pay particular attention to the
insulation surrounding the jaws.
•Use caution when working with voltages above 60 V
dc, 30 V ac rms or 42 V ac peak. Such voltages pose a
shock hazard.
•Do not use the Probe or Power Supply in wet
environments or in locations that hazardous gases
exist.
•Inspect the Power Supply and power cord and ensure
that they are not damaged.
•This product has no serviceable parts, do not open the
Power Supply.
•Check to make sure that the voltage selector switch on
the back panel of the Power Supply is set to the correct
mains input voltage before connecting power.

Probe Operating Instructions
The following sections list the Probe operating instructions.
Connections
For these connections, refer to Figures 1 and 2. To connect the Probe, do the
following:
1. Connect the BNC connector, to the oscilloscope input. Ensure that the
input impedance is ≥ 1 MΩ.
2. Connect a ±12 V external power supply to the power supply connector on
the Probe interface. Do not switch on the power supply until the power
supply connections are made using the power supply cable with or without
the adapter provided.
3. When measuring currents with fast voltage variations (high dv/dt) of the
primary current, connect the ground terminal on the Probe to ground.

Activating the Probe
There are two possibilities of supplying power to the Probe:
1. Use the recommended PSi50s Power Supply.
2. Use any suitable power supply and connect the power supply lead using
the adapter provided (see Figure 2).
Note
In order for the Probe to function correctly, the characteristics of the
power supply must be in accordance with the requirements in
“Specifications”.
Before activating the Probe, ensure that the Probe head is locked with no
primary conductor (see Figure 3).

When turning on the Probe :
•All the LEDs will light up for one second.
•Demagnetization is automatically started; the DEGAUSS LED will light
up for approximately six seconds.
•Auto zero is initiated to remove the residual offsets for the two ranges.
