Laurel Electronics LAUREATE SERIES COUNTER_TIMER - Manual (Page 28)

RATE AxB is the same as Rate A+B except that A is multiplied by B.
RATE A/B (Ratio) is the same as Rate A+B except that A is divided by B. Rate A and
B may be scaled such that the ratio of A/B is 1. When the value of B increases the ratio
is a number less than 1 and when it decreases the number is greater than 1.
RATE A/B-1 (Draw) is the same as Rate A/B (Ratio) except that 1 is subtracted from the
ratio to give a zero value when the ratio of the 2 inputs is 1. This is used in applications
where two rollers, etc. should be rotating at the same speed and displays the amount
of tension between the two rollers.
11.5 PERIOD
A ONLY, PERIOD A B Period of either channel A input or both A and B may be displayed.
If one channel is displayed the input is on channel A and decimal point1, scale1 and
offset1 apply to the input. If two channels are displayed decimal point1, scale1 and
offset1 apply to channel A and decimal point2, scale2 and offset2 apply channel B.
Either channel may be displayed by pressing and releasing the reset key . The displayed
period of the input signal is not affected by the gate time but the longer the gate time the
more periods of the input signal that are averaged. The shorter the gate time, the faster
the meter outputs and alarms are updated.
PERIOD A+B is the same as Period A, Period B except that Period A is displayed as item
2, Period B is displayed as item 3 and the sum of A and B is displayed as item 1. Decimal
point 1 applies to both A and B and decimal point 2 applies to the sum of A and B. The
resolution of the sum is determined by setting the multiplier (Resolution) from .00001 to
100000.
PERIOD A-B is the same as Period A+B except that B is subtracted from A
PERIOD Ax/B is the same as Period A+B except that A is multiplied by B.
PERIOD A/B (Ratio) is the same as Period A+B except that A is divided by B. Period
A and B may be scaled such that the ratio of A/B is 1. When the value of B increases
the ratio is a number less than 1 and when it decreases the number is greater than 1.
11.6 TOTAL
A ONLY, TOTAL A B Total of the number of pulses of either channel A or both A and
B may be displayed. If one channel is displayed the input is on channel A and decimal
point1, scale1 and offset1 apply to the input. If two channels are displayed decimal
point1, scale1 and offset1 apply to channel A and decimal point2, scale2 and offset2
apply channel B. Either channel may be displayed by pressing and releasing the reset
key or both channels may be reset using the external input "Function Reset". By setting
an offset in the meter and a negative scale factor, the meter counts down from a preset
value to zero.
