1.1 PRECAUTIONS FOR USE
The protection oered by this accessory is compromised if it is used in
unapproved, unspecied, 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 qualied personnel using
appropriate safety precautions.

2. 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.

3. 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 conguration, technical specications and error
messages, refer to the user manuals for the meters being used.
