•
Measurement Display—Displays the measurements, including the
type and units of the measurement.

–
Frequency—Measures the frequency of the unknown signal.
–
Totalize (Count Edges)—Counts rising edges and accumulates
the total.
–
Period—Measures the period of an unknown signal.
–
High Pulse Width—Measures the positive pulse width of an
unknown signal.
–
Low Pulse Width—Measures the negative pulse width of an
unknown signal.
–
Duty Cycle—Measures the percentage of time that an unknown
signal is high versus its period.
–
Time Between 2 Edges—Measures the amount of time between
a rising edge on one input and a rising edge on another input.
–
Phase Angle— Measures the phase difference between two
unknown signals of the same frequency.
–
Frequency Ratio—Measures the ratio of one frequency to
another.
–
Encoder-Position—Monitors the relative position and number of
revolutions of a motion encoder.
–
Encoder Speed—Measures the speed at which a motion encoder
moves.
•
Main Control Buttons— The main control buttons include Run,
Single, and Reset:
–
Run—Starts or stops the Counter acquisition.
–
Single—Acquires a single measurement.
–
Reset—Resets the Totalize (Count Edges) value or
Encoder-Position to 0.
•
Maximum Measurement Time (seconds)—Determines the time
taken during a frequency measurement or the amount of time to wait
before timing out for the other measurements.
