0 to 99,999 main total display plus 0 to 999 total overflow for a combined 8 digit total of 99,999,999. Alternating Display:
Display may be programmed to alternate between rate and total every 10 seconds. Time Base:
Seconds, minutes, hours, or days Totalizer Conversion Factor:
0.0001 to 99999 Totalizer:
Calculates total based on rate, time base of second, minute, hour, or day, and field programmable multiplier; stored in non-volatile memory upon power loss. Totalizer Rollover:
Total rolls over when total exceed 99,999,999. Totalizer Reset:
Manual reset or automatic with time delay, or disabled for non-resettable total applications.
Open Collector Output
Rating: Isolated open collector, 30 VDC @ 175 mA max.
Alarm Output: Assign to rate or total, high or low rate alarm.
Deadband: 0-100% of full scale, user selectable
Acknowledge: ACK button resets output and screen indication.
Automatic Reset: Alarm resets automatically when signal reaches the reset point.
Pulse Output: 250 pulses/sec max; pulse width: 3 ms, fixed. If the pulse output exceeds the maximum pulse output, counts are accumulated as pending and are not lost. One pulse per total increment, programmable from 0.0001 to 99999 (decimal point based on total selection).
* Below -20°C the LCD becomes less readable.
