iseg-nhr
Python interface for an ISEG NHR high-voltage power supply
Example
from iseg_nhr import NHR, Polarity
psu = NHR("COM3")
polarity = psu.channel0.voltage.polarity
print(polarity)
psu.channel0.voltage.setpoint = 1_000
psu.channel0.on()
print(psu.channel0.voltage.measured)
print(psu.channel0.current.measured)
