The DPF6000 microprocessorbased, 6-digit, 1⁄8 DIN panel
instruments can be configured by
front-panel keys or by a PC as
a frequency meter/tachometer,
frequency-ratio meter, period/
period-average meter, time interval/
time-interval-average meter, reset
stopwatch, and cumulative timer or
totalizer/1-stage batch controller.
Units are available with two signal
inputs to provide frequency ratio or
time-interval measurements. Five
operating modes.
In the frequency meter, the
minimum display update rate is
equal to 1 period of the frequency
input. Thus, very low frequency
measurements are displayed
and updated faster than most
conventional frequency meters.
Only two sensors are required
to measure the rate of a moving
object. The DPF6000 can be set-up
as frequency-ratio meter, ideal for
monitoring flow ratios.
DPF6100
The DPF6000 can be set-up as an
up or down totalizer/1-stage batch
controller at rates up to 7 MHz.
The display capacity is -99,999 to
999,999 counts with exponential
format up to 9.99 E9. Upon AC
