Most of the component parts are mounted on a printed circuit board which simpli-
fies assembly and maintenance, thus, extending the useful life of the Instrument.
The phenolic case is designed with heavy reinforced walls for maximum durabil-
ity and provides excellent protection for the circuit components. The case has an
externally accessible battery and fuse compartment. Access to the batteries and
fuses is obtained by unscrewing a single captivated screw at the bottom of the
case and sliding out the compartment cover.
Rubber plug bumpers on the bottom of the case reduce sliding should the 260 be
accidentally pulled by the test leads when the Instrument is on a workbench.
A carrying handle is attached to the Instrument case. The handle may be used to
support the Instrument in a convenient sloping position for easy viewing. The
case can also be placed in either a vertical or horizontal position. The horizontal
position is preferable for greater accuracy since the Instrument is calibrated in
this position.
Each Instrument is furnished with one pair (Catalog Number 00043) of probe
type test leads (one red and one black, each 48 inches long) for all applications
of the Instrument. These test leads have elbow prods on one end, to connect the
leads to the recessed jacks on the Instrument front panel. The probe tips at the
opposite end have threaded shoulders to accept the screw-on insulated alligator
clips (furnished with the test leads) or the 5000 volt test probe(s) to extend the
Instrument AC or DC voltage range. The test leads and the insulated alligator
clips are rated for the voltage and current ranges available on the 260. Maximum
ratings are 1000V AC or DC or 10 DC amperes. These ratings for the test leads
must not be exceeded in any application.
