Usage

from pytza500 import TZA500, GAIN, UNITS, BANDWITH

# List all available devices
devices = TZA500.find_devices() # Get all available devices
print("Available Devices: {}\n\n".format(", ".join(devices) if len(devices) > 0 else "None"))

# Create TZA500 instance
tza = TZA500()

# Connect to first TZA500 device in list
tza.connect(devices[0])

tza.tza_set_polarity(False) # Set polarity to not inverted

tza.tza_set_auto_zero() # Set initial auto zero

# Or set initial auto zero reset
tza.tza_set_auto_zero_reset()


tza.tza_set_bandwith(BANDWITH.KHZ_10) # Set bandwith to 100 kHz

# Set wavelength
tza.tza_set_wavelength(660)

# Set gain
tza.tza_set_gain(GAIN.X1)

tza.sensitivity = 1.0 # Set sensitivity (only for watt units)

# Set unit to use in measurements
tza.set_unit(UNITS.MICROAMPERE)

# Print single measurement
print(format(tza.tza_get_measurement(), '.8f'))

tza.disconnect()
