MODEL PC100 TEMPERATURE CONTROLLER USER MANUAL

1. The PC100 can be calibrated in two ways calibrate to a standard and calibrate at 0 and 100 deg C Calibrating at 0 and 100 deg C must be performed if the probe type is to be changed This method is explained in Section 7 Changing Probe Types Ifthe probe type is not changed the calibrate to a standard method can be used This method is explained below and is accessed from the menu Answering yes to this menu item will invoke a group of commands to calibrate the probe to your in house standard at your facility The basics of calibrating to a standard will be explained and then the menu prompts will be explained Before leaving the factory each unit is calibrated for the probe type specified when the PC100 was ordered However there is the ability to re calibrate the unit at your facility using an in house standard if so desired Calibrating the PC100 to a standard requires placing the probe at two temperatures and entering the values at these two temperatures into the unit The temperatures can be any two temperatures that you choose These readings would be obtained from the in house measurement device The menu is set up such that each temperature is entered separately Only one temperature can be entered each time through the menu After the first temperature is entered the menu must be exited and then re entered to enter the second temperature To obtain the best results the two temperatures should be reasonably far apart The first prompt d
