Down counting from preset to zero using negative scale factor. Data rates up to 2 MHz. Green or red LED display. A total and Channel B rate simultaneously. Counting on Channel A, using Channel B to inhibit counting.
Countdown operation is set up by entering a negative scale factor.
Scaling allows direct readout in engineering units, such as gallons or cubic feet based on counts from a turbine flowmeter, or the count of cans based on the count of six-packs. The totals are stored in non-volatile memory so as to be retained in the absence of power. Channel A can display total while Channel B displays rate. The selection of A or B for display is via a front panel pushbutton. This mode is ideal for flow applications.
