Introduction
About Cal Test Electronics
Since 1995, Cal Test Electronics has provided high quality accessories to
an ever-evolving test and measurement market. From the standard to
the unique, Cal Test offers solutions to fit any need.
Founded to provide original equipment manufacturers (OEMs) with
custom test accessory solutions, the company has expanded, supplying
its own name-brand products to a network of world-class distributors.
In 2009, Cal Test purchased Global Specialties along with their offering
of educational electronic products.
For most of its 20-year history, Cal Test has enjoyed a close relationship with
B&K Precision Corporation, a prominent test instrument manufacturer,
through a mutual shareholder position. Although both companies maintain
separate corporate identities, their strong affiliation allows each to stay
at the forefront of their respective markets. Their joint relationship allows
B&K Precision to market the Global Specialties educational line through
its international distributors, and Cal Test to be the sole supplier of test
accessories to the B&K Precision instrument line.
To strengthen its European presence, Cal Test partners with Sefram
Instruments SAS, a B&K Precision subsidiary, and markets selected
products under the ELDITEST brand, a time-honored name in Europe.
With the 2013 acquisition of Pintek Electronics, Ltd., a well-known and
respected Taiwanese test equipment manufacturer, Cal Test significantly
increased its resources for manufacturing both standard and custom
products.
Today, Cal Test provides one of the most complete test accessory
offerings available on the market, which include:
• Oscilloscope probes – passive, active, and high voltage
• DMM probes, leads, and complete accessory kits
• Banana plugs, jacks, and test lead assemblies
• Coaxial adapters and cable assemblies
• Test lead wire and storage racks
By following the latest technological advances in electronics, Cal Test
regularly develops and introduces new products to meet the ever-changing
needs of the test and measurement industry. We look forward to serving
you in the decades to come.
Sincerely,
Bill Hansen, President

Fused Probes
ELDITEST Brand
The CT399x series fused probes enhance user safety when working in high
energy CAT III and CAT IV environments. The replaceable fuse provides fast
interrupt in fault conditions. The probes feature a 1 MΩ resistor in parallel
with the fuse. Although it is recommended to check for a blown fuse before
and after the measurement, if the probe is used with a blown fuse, the
parallel resistor will provide a 90% accurate measurement thereby avoiding
a “zero” instrument reading when there is a hazardous voltage present.
• IEC 61010-031 rated
• Replaceable 1,000 VAC / VDC, 11 A, 20 kA IR fast-acting fuse
• 1,000 V CAT III / 600 V CAT IV IEC voltage rating w/protective cap

Kelvin Clips
Kelvin Clips are used to perform
four-terminal sensing and are
also known as Kelvin sensing.
This 4-wire sensing, or 4-point
probe method, is an electrical
impedance measuring technique
that uses separate pairs of
current-carrying and voltage-
sensing electrodes to make more
accurate measurements than
traditional two-terminal (2T)
sensing. A Kelvin Clip, is often
a crocodile clip, that connects
a force-and-sense pair when it
closes onto a conductor.

This adapter kit allows you to create any combination
of in-series and between-series coax adapters for
BNC, N, F, TNC, RCA, UHF, Mini-UHF and SMA
connectors. This is done by screwing together two
separate adapters to a universal center adapter.
All pieces are machined brass with Teflon dielectrics
and gold plated center contacts. Whether field service
or bench, this adapter kit provides an easy solution to
coaxial connection requirements.

BNC, 50 Ω, Male to Female Attenuators
Instrument grade BNC male to female 50 Ω fixed coaxial
attenuators are linear, passive transmission line components
designed to reduce the input power in a matched system. They
are intended for laboratory, production, testing and system use.
Typical applications include VSWR reduction at the insertion
point, range extension of power meters, RF path loss simulation,
and isolation or power level reduction of signal sources.

– For E and H, minimum values with plastic tip, other wise spacing shall be at least .10″ (2.6 mm)
– Tolerance on dimensions not otherwise noted: ± .004 (0.1 mm)
Measurement Categories:
(Per IEC 61010-031)
Measurement categories are based on location as related to the mains supply where measurement can be made.
0 (no category) – circuits that are not directly connected to mains.
Examples are automobiles or other battery operated circuits or devices.
Category II – applicable to circuits connected directly to sockets outlets of the low-voltage mains.
(CAT II) Examples are consumer appliances, power tools, or the consumer side of socket outlets.
Typical short circuit currents: < 10 kA
Category III – applicable to circuits connected to the distribution part of a buildings low-voltage mains.
(CAT III) Examples are power distribution boards, solar cell power assemblies, circuit boxes, circuit breakers,
switches and industrial equipment.
Typical short circuit currents: > 10 kA
Category IV – applicable to circuits connected at the source of the buildings low-voltage mains.
(CAT IV) Examples are measurements on devices installed before the main fuse or circuit breaker in a building.
Typical short circuit currents: > 50 kA
These are high energy circuits so great precautions must be taken while working with these.
The measurement category of a combination of probe, lead and or accessory is the lower of their respective category ratings.

4 mm BANANA JACK 4 mm BANANA PLUG
Ø K
Ø G
Since its introduction over 90 years ago, the banana plug connector
has become the standard single wire connection device for electronic
and electrical test equipment. The plug has evolved into a high quality
copper alloy contact spring that plugs into a 4 mm (.157”) diameter
banana jack (socket). The standard spacing for two banana jacks
side-by-side is 19.06 mm (.75”).
With the introduction of safety standards in the 1980’s, banana plugs
acquired a cover sheath over the exposed metal contact to enhance
user
protection. The current international safety standard, IEC 61010-031,
Safety requirements for electrical equipment for measurement, control and
lab use – Part 031: Safety requirements for hand-held probe assemblies
for electrical measurement and test, defines dimensions of sheath
banana plugs for measurement categories II, III or IV up to 1,000 V.

Technical Reference
Banana Plug (Type D)
Features an exposed compliant contact spring and an insulation
housing. It plugs into both standard and safety 4 mm banana jacks.
Although it can operate at much high voltages, the plug is not
recommended for handheld use above 30 VAC / 60 VDC (IEC 61010-031)
as the exposed contact is capable of rendering an electric shock.
Stacking Banana Plug (Type D)
Has a banana plug on one end and a banana jack (receptacle) on
the other end of its insulated housing. This allows another banana
plug to share the same test point.
Sheath Banana Plug (Type A)
Also known as a shrouded, sleeved or safety banana plug. It
features a fixed protective sheath over the spring contact that
prevents unintentional contact. This plug only fits into safety banana
jacks, which feature a recessed ring around their connection jack.
This plug is recommended for all CAT III and IV applications.
Stacking Sheath Banana Plug (Type A)
Similar to the stacking banana plug, the plug features a sheath
banana plug on one end and a safety banana jack on the other.
Recommended for all CAT III and IV applications.
Retractable Sheath Banana Plugs (Type A)
Feature a spring-loaded protective plastic sheath that prevents
unintentional contact yet slides back when engaging a banana
jack. An insulator tip on the plug’s contact provides further user
protection. Retractable sheath banana plugs are for CAT II
applications.
Stacking Retractable Sheath Banana Plug (Type A)
As with the other stacking banana plugs, it features a plug and a
female jack in its housing. But, the retractable sleeve over the plug
makes it one of the most versatile banana plugs available, usable
with all types of banana jacks. Retractable sheath banana plugs are
for CAT II applications.

Within the scope of IEC 61010-031 there are four defined probe
assembly types that include banana plugs. The types are A, B, C & D
with banana plugs falling under types A and D.
Type A: Non-attenuating assemblies rated for direct connection to
voltages exceeding 30 Vrms / 42.4 Vpeak / 60 VDC.
Type D: Non-attenuating assemblies rated for direct connection to
voltages not exceeding 30 Vrms / 42.4 Vpeak / 60 VDC.
Below are descriptions of the most common banana plugs.
