DUTY:
The Duty Cycle function measures the percentage of time the CLK (clock) is high as a percentage of
the total time of the signal. The Duty Cycle function may be used to measure the percent ‘power’ or servo
control position being controlled by a PWM (pulse width modulation signal.
Duty Cycle = x/y%
•
DELAY:
The Pulse Delay function measures the delay in time between Signal Line 1 (CLK 1) and Signal Line 2
(CLK 2) turning ‘ON.’ The Pulse Delay function may be used to measure the time between two signals
turning on or the phase angle of AC signals with suitable signal conditioning.
Counter Measurements
I/O Signal
Description
CLK_A
Measures the positive or negative pulse depending on the signal type and
modifier chosen.
RST
Resets the counter to 0 depending on the signal type and modifier chosen.
ENB
Sensor starts measuring depending on the signal type and modifier chosen.
DIR (Up/Down
only)
Determines what aspect of the pulse is counter (Up or Down) depending on the
signal type and modifier chosen.
•
CNT:
The Counter function measures the number of OFF to ON transitions on the CLK signal. The counter
function may be used to measure the number of occurrences of an external event.
•
U/D_CNT:
The Up/Down Counter function measures the number of OFF to ON transitions on the CLK signal.
The Up/Down Counter function may be used to measure the number of occurrences of an external event or
the positioning of external devices based on a suitable transducer.
