short usb_tc08_legacy_get_cold_junction
(
long * temp,
short handle
)
This routine retrieves a cold junction temperature reading. This can also be achieved
by passing
hundredths of a degree Celsius. Normally, you do not need to worry about the cold
junction temperature, as the driver automatically uses it to compensate
thermocouples. You can, however, use it as an indication of ambient temperature.
Arguments
Returns
to usb_tc08_get_temp. Temperatures are returned in
channel = 0
handle
Specifies USB TC-08 unit.
temp
Pointer to a location where the temperature reading is to be
stored.
0
Use usb_tc08_get_last_error.
1
