sory offers

both

in- and out -of- circuit

test capabilities.

components.

The accessory compares

a suspect

one,

eliminating

tedious pin

testing.

Connected

to any

dual

shorts

opens,

diode action

and

leak-

age

by applying

up

to 14

volts rms at

300

mA

to compare

unpowered

de-

vices.

It displays

both

good and

bad

signatures

of

the component

being

tested.

Results

are displayed

as

a

graphic

waveform,

rather than

in a

numeric

format that

requires

inter-

pretation.

Major differences

in com-

ponent

signatures

indicate

a malfunc-

tion

in the device

being tested.

Supplied

are an operators
