Software Section:
1.Constant Acquisition Rate:The developed system is an improvement over
the conventional system since the acquisition rate of the data is uniform and is
not dependent on the user.This increases the reliability of results by ensuring
that an optimum number of observations are taken.The temperature inside
the oven used in the experiment varies at a slower rate at lower temperatures
and at a faster rate as the temperature reaches 150°C.The students thus fail
to take observations at equal intervals of temperature increase during rapid
heating or cooling of the system.This limitation is taken care of by maintaining
a constant acquisition rate for the entire range of temperature increase.The
observations can be taken for both increasing as well as decreasing
temperature.
2.Online Plotting and Calculations:The calculations for resistivity and ln ρ
values are estimated online for every data point acquired in the VI.This acts
as an obvious advantage over the conventional system which involved a lot of
student time in experimentation and its analysis.The online estimation of
these values helps the student to analyse the readings taken during
experimentation.In case of any discrepancies in results,an appropriate
remedial action can be taken.
Hardware
This set up reduces the error in the temperature measurements in comparison to
using a thermometer.Also,during rapid increase of temperature,the delay in the
reading of temperature and voltage by the user in the manual mode may result in
errors in the observations thus giving erroneous results.These problems in the
present set up have been removed by the use of a temperature sensor and the
USB 6008 DAQ card which can read the analog input data up to a maximum
speed of 10kS/s which is much higher in comparison to the rate of temperature
increase.
