This Counter can obtain a resolution of 0.1Hz by allowing the more significant figures of the counter to overflow.

Five 7 segment light emitting diodes (LED's) provide a visual numeric display.

The decimal point is automatically positioned and leading zeros (to the left of the most significant digit or decimal point) are blanked.

Digit overflow is indicated by a front panel LED.

Signals to be counted timed can be applied to either a front panel BNC connector or to the rear interface connector.

Internal switches select frequency or rpm operation, internal time base or external standard, and override display storage.
