Internal Oscillator Self Check

he UC10A is a feature-packed,
highly accurate universal counter
that measures frequency, period,

T

frequency ratio of two input signals, time
interval between two input signals, and
unit count (totalize mode). It measures
frequency from 5Hz to 100MHz with an
input sensitivity of 20mV over the entire
range. Four user-selectable gate times
allow measurements at four levels of
resolution. Push buttons provide easy
access to six functional capabilities, four
gate time selections, attenuator, input
frequency range, and reset. Function
selections are indicated by a combination
of an LED indicator and a distinctive
annunciator tone. A large, 8-digit LED
indicates all readings. OVER, GATE, kHz
and µsec are separately identified by
LEDs. A built-in 10:1 attenuator mini­mizes false counting by reducing sensitiv­ity and thus noise effects. To verify
internal time base generator and counter
accuracy, the UC10A has complete self­check capability.

The UC10A is housed in a stylish case,
featuring a cushion grip carrying handle/tilt
stand, rear cord wrap, and recessed areas in
the top cover for easy stacking of multiple
units.
