1)
Maximum continuous power available is derated linearly from 100% of maximum at 40 °C to 75 % of maximum at 55 °C.
2)
Conductance (S) = 1 / resistance (
Ω
).
3)
The setpoint is 10 times larger than the rise rate in CCL mode (constant current low level range).
4)
The momentary transition time is defined as the time required for the input to change from 10% to 90% or from 90% to 10% of the programmed excursion.
5)
Transient frequency depends on the time for high/low level and rising/falling edge.
6)
Full remote control via RS232 with optional GPIB and USB.
