Setting MYPIN Temperature Offset

From Tom - http://goo.gl/22lW4R Because of very slight alloy differences K type thermocouples don't come from the factory zeroed in. The alloy differences result in a measurement offset. PID manufacturers know this and they give you the ability to correct for the offset and once this is done your measurements will be very accurate across whatever range you are measuring. This video shows you how to set your MYPIN temperature offset. It's a setting you only need to make once and then any time you replace your thermocouple. To start calibrating fill an insulated cup with ice then top off with water to about ¼” from the top. A insulated cup is important because without insulation as the ice melts the water at the bottom of the cup will be up to 2 degrees warmer than the ice. Start your PID and place your thermocouple in the ice water then wait about 15 minutes for the temperature to stabilize. Once stabilized note your temperature – if it’s high then we will add offset to bring the temperature down. If it’s low we will add negative offset to bring the temperature up. To add or remove offset hold the SET button down for at least 3 seconds, until AL1 is displayed. Now press & release the SET button until PUF is displayed. Press the AT button and the right most digit will flash. Use the UP/DOWN buttons to set. Press the AT button again to adjust the next digit. When done press the SET button to save the changes. Note: The offset steps are not in degrees, they are in measurement units, and you will not be able to offset the exact value. Just like the video shows you will need to set, test and adjust until it’s right.
