After that has happened, enable temp compensation at a value of 2.2 to start. For the first calibration, get your tank temp as close as possible to 77F and float the calibration packet for at least 15 minutes. Before doing the dry part of the calibration lightly rinse the probe in RODI and pat dry. For the 53mS step, use a clip or magnet to keep the packet touching the water and and calibrate the probe there giving it about 5 minutes to settle. Once calibrated, keep an eye on the relationship between conductivity and temperature. If cond rises as temp rises, you need to bump the compensation value up by 0.1 and vise versa if there is an inverse relationship. If cond stays within a band of 0.2 to 0.3 max to min your compensation is dialed in.
Once this has all been done, tank temp no longer matters for calibration as long as the packet is the same temp as the tank. Calibrate quarterly or whenever the readings appear to be drifting.
You might be an engineer if...You have no life and can prove it mathematically.
