INSTRUMENT DESCRIPTION
LOW BATTERY
is indicated by “LOBAT” on the display, in
addition to the resistance reading.
Four binding posts
are provided for the connection of test
probes. (Only HTP-101A or SKP-8 test probes may be used in
an explosive atmosphere). The two binding posts lI
and -I supply a constant current to the resistance under test.
The binding posts labeled +E and -E sense the voltage
developed across the resistance under test. The binding posts
are color coded to match the colors of the spade lug
insulations on the supplied test probes.
Test Probes
The Model R1L-E2A unit is shipped with one or both of the test
probes: a pair of pistol-shaped test probes (HTP-101A) and/or
a pair of Kelvin Probes (SKP-8). The probes are color coded; a
red one for use with the left hand, and a white one for use with
the right hand. Each probe is attached to an eight foot length
of cable comprised of two 12 AWG insulated wires for the HTP-
101A and 18 AWG insulated wires for the SKP-8. The ends of
the probe cables terminate in spade lugs, which have color
coded insulation corresponding to the colors of the front panel
binding posts. The cable strain relief has a band with
appropriate left or right identification.
Each test probe has two sharply-pointed spring-loaded
conductors extending from the nose. One conductor of each
probe is for current, and the other is for voltage.
When firmly pressed against a surface, the pointed conductors
of the HTP-101A retract with a rotating motion, to help cut
through non-conductive surface films. When not in use, the
probes are meant to be stored in the lid of the R1L-E2A case.
