BASIC OPERATION
When power is applied to the unit, it performs an internal self-diagnostic test
and then the unit displays its revision level. If all P’s appear in the display, press
the select (SEL) button and check all of the data setups.
The CUB5 can be programmed to function as a single counter, dual counters,
single counter with rate indication or dual counters with rate indication.
Counter
The CUB5 receives incoming pulses and multiplies them by the Count Scale
Factor. The unit’s counter (internal count value) keeps track of the scaled input
pulse count which results in the desired reading value for the count display.
Input A accepts the signal for the count and Input B is used for quadrature, dual
counter, anti-coincidence counting, or up/down control counting.
The count(s) reset to zero when a manual reset is performed. At loss of power
to the unit, the contents of the counter are saved. This allows counting over
consecutive shifts, days, etc. The total count can accumulate to 99,999,999.
The “B” counter, if enabled, can accumulate 9,999,999 counts.
Note: The counter value will roll over and flash “tot OVEr” when the count
value exceeds 99,999,999, indicating an overflow condition. The “B”
counter, if enabled, will roll over and flash “btot OVEr” when the count
exceeds 9,999,999.
Rate
The signal at Input A is for the Rate indicator, which uses a time interval
method (1/tau) to calculate the rate value. The unit counts on the negative edge
of the input pulses. After the programmed minimum update time elapses and
the next negative edge occurs, the unit counts the number of edges that occurred
during the elapsed time. The number of edges is multiplied by the rate scaling
value to calculate the rate value. At slower rates, averaging can be
accomplished by programming the rate minimum update time for the desired
response. Extensive scaling capabilities allow practically any desired reading
at very slow count rates.
DISPLAY SELECTION
In the normal operating mode the program terminal is not connected to
common. The display indicates either:
Rate value designated by an “R” to the left of the display,
“A” count value (no designator), or
“B” count value designated by a “b” to the left of the display
If the Select button is enabled, the display may be toggled by pressing the
select button. If display scroll is enabled, the display will toggle automatically
approximately every four seconds between the rate and count values. If both
the select button and display scroll are enabled, pressing and holding the select
button pauses the automatic toggle (if enabled) as long as the select button is
held.
