5.6 Select the number of channels and set the print interval of 30 minutes on the data logger.
5.7 Start the mapping after stabilization of the displayed temperature.
5.8 Record the temperature readings of each probe in temperature mapping record.
5.9 If results do not fall within the specified limit, take necessary corrective actions to rectify the failure & perform the mapping again.
5.10 Final report for temperature mapping to be prepared by officer/ executive of the concerned department based on results obtained indicating the summary and conclusion.
