306 To Order (Specify Model No.) AVAILABLE FOR FAST DELIVERY! The DPF5100 Series microprocessorbased, 6-digit, 18 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, time-interval/time-intervalaverage meter, reset stopwatch, cumulative timer or totaliser/ 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 totaliser/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.
