1. I-High can be set from -105mA to +105mA (default is 1mA).
2. I-Low can be set from -105mA to +105mA (default is 0mA).
3. Pulse Width can be set from 50µs to 12ms (default is 110µs).
4. One 60Hz power line cycle = 16.667ms (1/60)
One 50Hz power line cylce = 20ms (1/50)
5. With Interval set to 5 PLC (power line cycles):
60Hz: One Pulse Delta cycle = 83.33ms (5/60)
50Hz: One Pulse Delta cycle = 100ms (5/50)
6. Interval can be set from 5 to 999999 PLC (default is 5 PLC).
