The DPF5100 Series
microprocessor-based, 6-digit,
1
⁄8 DIN panel meters can be
configured by front-panel keys or
via a PC as a frequency meter/
tachometer, frequency-ratio meter,
period/period-average meter, timeinterval/time-interval-average meter,
reset stopwatch, or cumulative timer
or totalizer/1-stage batch controller.
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 on most
conventional frequency meters.
Only 2 sensors are required to
measure the rate of a moving
object. The DPF5100 can be set up
as a frequency-ratio meter, ideal for
monitoring flow ratios.
The DPF5100 can also function
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.
The latest reading is automatically
saved in non-volatile RAM and is
restored on power-up.
