1 Scaled output pulses have a fixed width of 100ms. Maximum pulses per second is 6.5Hz
2 For pulse frequencies <1 Hz, increase setting in SET F menu to 3 or higher.
3 When calculating total resistive load for loop power (volts/.020 amps = ohms) be sure to subtract 400 Ω from the total to account for basic operation
