Definition of Measurement Categories (CAT)

CAT IV:
Corresponds to measurements performed at the primary electrical supply (< 1000 V). Example: primary overcurrent protection devices, ripple control units, and meters.

CAT III:
Corresponds to measurements performed in the building installation at the distribution level. Example: hardwired equipment in fixed installation and circuit breakers.

CAT II:
Corresponds to measurements performed on circuits directly connected to the electrical distribution system. Example: measurements on household appliances and portable tools.

PRECAUTIONS FOR USE

The protection offered by this accessory is compromised if it is used in unapproved, unspecified, or improper ways. These safety warnings are provided to ensure the safety of personnel and proper operation of the instrument.

Observe the maximum voltage, intensity, and measurement category. Do not use the accessory on networks where the voltage or category exceeds those stated in this manual.
Observe the conditions of use (e.g. temperature, humidity, altitude, degree of pollution and location of use).
Do not use the accessory if it is open, damaged, or incorrectly reassembled.
Any repairs must be carried out by trained and qualified personnel using appropriate safety precautions.

ORDERING INFORMATION

Kelvin Probes Pistol Grip, 10 ft, 25 A Spring Loaded: Cat. #2118.84
Kelvin Probes Pistol Grip, 20 ft, 25 A Spring Loaded : Cat. #2118.85

PRODUCT FEATURES

The pistol-grip spring loaded 25 A test probes can measure low resistances very accurately using micro-ohmmeters with (.157 to .236) in (4 to 6) mm diameter binding posts or .157 in (4 mm) diameter safety terminals.

The pistol-grip spring loaded test probes ensure good contact at the measurement point even if the surface is uneven.
Each 25 A test probe has very low resistance.
The measurement is made in 4-wire mode, so lead resistance compensation is not necessary.

NOTE: At the other end of the leads, there are .157 in (4 mm) diameter safety terminals that spaded lugs .236 in (6 mm) diameter screw into. These probes can be used with micro-ohmmeters having either binding posts from (.157 to .236) in (4 to 6) mm in diameter or safety terminals .157 in (4 mm) in diameter.

SPRING LOADED PISTOL 25 A KELVIN PROBE

Parts Description

OPERATION

Connect the two spring loaded 25 A test probes to the four terminals of the instrument.
Loosen the nuts on the binding posts. Insert the spaded lugs while carefully connecting the red leads to the voltage terminals (P). Then, tighten the nut.
If the instrument has safety terminals, unscrew the spaded lugs to make the connection

For details of the measurement configuration, technical specifications and error messages, refer to the user manuals for the meters being used.
