PRODUCT DESCRIPTION

AT-F Series Frequency Counter is 8-bit high-brightness LED display advanced frequency counter with, 4 function operation, low power circuit design, small size, and light weight. It have a high-stability crystal oscillator temperature protection (TCXO high temperature stability of security compensation oscillator 13MHz) to ensure measurement accuracy and wide to check the input signal with frequency, period and cumulative.

It has the self-test features such as the choice of input signal attenuation function.  The feature and functions are controlled by a large-scale microprocessor.

 

FEATURES

8-Digit LED display
Few switches, Well operability
Quickness, High resolution

Compact Design, Excellent for field operations

Self-locking manual lock
Zero reset
