Analyze Capacitors, Coils, And

High-Voltage Components,

Automatically: The LC102 a uto-z is

microprocessor contr olled for speed and

accuracy, with extended ranges to meet
all your cap/coil testing needs. Enter the
value, rated voltage, and tolerance— the

AUTO-Z makes the readings, compares to

EIA tables stor ed in memory, and dis

plays if the component is good or bad.

Prot ects You And Your
Instrument From Charged
Capacitors: An audible and visual alert

warns you if the AUTO-Z’s internal
discharge circuit fails or the test lead fuse
blows.

Portable—Use In The Shop,
Field, Or Factory: The LC102 packs

full inductance, capacitance and
resistance analyzing power into a
lightweigh t, portable (battery and AC)
package. It' s designed with CMOS logic,
LCD technolog y and auto m atic shut-off
for long battery life (operates nine hours
on a single charge).
