Phase Angle In this mode, the meter determines the phase angle between the signals
on Channel A and Channel B. The phase angle is measured from 0 to 360
degrees
Pulses The menu item pulses is used to set the number of pulses generated by
a quadrature encoder for each zero index pulse. The setting is equal to
the number of pulses per revolution of the encoder (times 2 or 4 if the count
by 2 or 4 is selected on the signal conditioner) times the scale factor.
Rate This is the same as frequency except that a scale factor is applied to the
input signal to display in engineering units such as RPM, gallons per hour,
etc.
Resolution This is a menu item that controls the resolution of the arithmetic functions
(A+B, A-B, AxB, A/B, A/B-1). The displayed value may be multiplied by
0.00001 to 100,000 in decade steps.
Scale Scale is the menu item that allows an input to be scaled in engineering
units. The scale factor consists of two parts; the scale factor is a multiplier
that may be set from 0.00001 to 9.99999 and a multiplier from 0.00001 to
100,000 in decade steps. When scale is selected, the most significant
digit flashes allowing the value of that digit to change, pushing the digit
select key moves the flashing digit to the right. When the right hand digit
is flashing, pushing the digit select key again causes the multiplier to be
displayed. Pushing the value select key changes the value of the
multiplier. The next time the digit select key is depressed, the display goes
back to the scale factor.
Time Interval Time interval is the measure of time between the occurrence of a pulse on
Channel A and Channel B. The time may be measured from the leading
or trailing edge of the pulse on A to the leading or trailing edge of the pulse
on B.
Time Out When making conversions, the gate time is started on an edge of the input
signal and ended on the same edge. If no input is received, the meter will
never update. The time out setting allows a wait time from .01 seconds
to 199.99 seconds for the meter to receive a signal. At the end of time out,
the meter updates and displays 0. The longer the time out, the lower the
displayed value of the input frequency. A shorter time out allows the meter
to update at a higher rate.
V-to-F Converter The voltage to frequency converter takes voltage or current inputs (0 to
1mA, 4 to 20mA, 0 to 10V) and converts them to a frequency. This allows
the meter to totalize an analog input as well as displaying rate. In addition,
for differential pressure transducers, the meter can calculate the square
root of the rate input and display total. Nonlinear analog inputs may be
linearized using the custom curve function.
