AC Current Probe
Models SR601 and SR604

User Manual

DESCRIPTION: The SR601/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 up to 1000Arms
continuous and are compatible with any AC ammeter, multimeter, or other current measurement instrument
with an input impedance lower than 5Ω. To achieve the stated accuracy, use the SR601/SR604 with an
ammeter having an accur ac y of 0.7 5% or better.

WARNING

The safety warnings are provided to ensure the safety of personnel and proper operation of the
instrument. Read the instruction completely.

• Use caution on any circ uit: potentially high voltag es and currents may be prese nt and may pose a
shock hazard.

• Do not use the probe if dama ged. Al ways co nnect th e cur rent pr obe to the m easuri ng devi ce bef ore it

• Do not use on non-insulated c onduct or with a potential to gr ound gr eater tha n 600V CAT III pollution

2. Use extreme caution when clamping around bare conductors or bus bars.

• Before each use, inspect the probe; look for cracks in housing or output cable insulation.

• Do not use clamp in wet environment or in locations that hazardous gases exist.

• Do not use the probe anywhere be yond the tactile barrier.

INTERNATIONAL ELECTRICAL SYMBOLS

This symbol signifi es t hat the c urre nt prob e is p rotect ed b y dou ble or r einforc ed ins ulat ion. Us e onl y
factory specified replacement parts when servicing the instrument.

This symbol signifies CAUTION! and requests that the user refer to the user manual before using
the instrument.

This is a type A current sensor. This symbol signifies that application around and removal from
HAZARDOUS LIVE conductors is permitted.

DEFINITION OF MEASUREMENT CATEGORIES
CAT II: For measurements performed on circuits directly connected to the electrical distribution s ystem.

Examples are measurements on household appliances or portable tools.

CAT III: For measurements performed in the building installation at the distribution level such as on

hardwired equipment in fixed installation and circuit breakers.

CAT IV: For measurements performed at the primary electrical supply (<1000V) such as on primary

overcurrent protect ion devices, ripple control units, or meters.

RECEIVING YOUR SHIPMENT

Making Measurements with the AC Current Probe Models SR601/SR604

• Connect the black lead of the current probe t o “common” and the red l ead to the AC curre nt input o
y

our DMM or other curr ent measuring instr ument. Select the appr opriate current r ange (2A AC range).
Clamp the probe around the conductor to be tested with the arro w pointed toward the loa d. If t he r ea din g
is less than 200mA, sel ect th e l o wer ra nge u nti l yo u obt ain the best resolution. R ead th e valu e di splay on
the DMM and multipl y it by the pr obe r atio (10 00/ 1). (If re ading = 0. 65 9A, the c urren t flowin g thro ugh the
probe is 0.659A x 1000 = 659A AC)

• 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 p robe jaw mati ng surfaces are free of dust and con tamination. C ontaminants c ause air
gaps between the ja ws, increas ing the phase s hift betwe en primary an d seconda ry. It is very cri tical for
power measurement.

MAINTENANCE
Warning:

• For maintenance use only original replacement parts.

• To avoid electrical shock, do not attempt to perform any servicing unless you are qualified to do so.

• To avoid electric al shock and/or dam age to the i nstrum ent, do no t get wat er or othe r foreign a gents int

t

he probe

Cleaning:

To ensure optim um performa nce, it is important to k eep the pr obe jaw mati ng surfaces clean at all times.
Failure to do so may result i n err or in r e adi n gs. T o c lea n th e pr obe j a ws , us e ver y fin e s an d pa pe r (fin e 600)
to avoid scratching the jaw, then gently clean with a soft oiled cloth.

REPAIR AND CALIBRATION

You must contact ou r Servic e Center f or a Cust omer Serv ice Aut horizati on num ber (CSA# ). This will ensure
that when your instrum ent arrives, i t will be track ed and processed pr omptly. Please write the CSA# o n the
outside of the shipping container.
