is a number less than 1 and when it decreases the number is greater than 1.
11.7 TIME INTERVAL
TIME INTERVAL A TO B measures time between an input on channel A and an input
on channel B. Time measurement starts when a pulse is applied to channel A (positive
edge if slope A is 0, negative edge if slope A is 1) and the measurement ends when a
pulse is received on channel B (positive edge if slope B is 0, negative edge if slope B
is 1). A single pulse may be measured by tying input A and B together and selecting a
positive or negative edge to start (Slope A) and the opposite polarity edge to stop (Slope
B). If a number of start and stop pulses occur during the gate time, the value displayed
is the average of the pulse widths. The value is updated at the end of each gate.
11.8 STOPWATCH
STOPWATCH A TO A measures time between an start pulse on channel A and a
second pulse on A to stop timing. Timing may be set to start and stop on either the
positive or negative edges of the pulses (Slope A). The time (item #1) may be displayed
in seconds, minutes or hours (with decimal point) using scale and multiplier with the
clock time display (hr, min, or sec)selected. Clock time (fixed format) displays
HH:MM:SS. Time is reset to 0 when a new start pulse occurs. Item #2 displays the
accumulated total time of Item #1.
STOPWATCH A TO B measures time between an start pulse on channel A and a stop
pulse on B. to stop timing. Timing is the same as A to A except in addition to separate
start and stop pulses, by tying input A and B together, a single contact closure may start
and stop timing by selecting the opposite Slope for A and B.
11.9 PHASE ANGLE
PHASE ANGLE A TO B measures the phase relationship between a signal on input A
and input B. The displayed value is 0 to 360 degrees. Resolution is determined by Scale
1.
