How to adjust Remote Reading Dial Thermometer with Adjustable Pointer
1) Place the entire temperature sensing bulb in a known ambient air temperature or a known liquid bath such as an ice bath at 32 degrees Fahrenheit (zero degrees Celsius).Be sure that the sensing bulb is in the known ambient air temperature or the liquid bath for at least fifteen-to-twenty minutes before checking the calibration accuracy and determining whether or not the thermometer requires recalibration.
2) If the thermometer reads something other than the correct temperature, proceed to Step 3.
3) Remove the acrylic (plastic) lens by carefully prying it from the case using a small standard screwdriver. Position the flat side of the screwdriver between the plastic lens and the metal stainless steel case. You will have to pry the lens up in several locations around the circumference of the case before you can lift it completely off the case.The lens is held in the case by friction and does not need to be twisted or rotated during removal or replacement.
4) You will notice that the pointer has a small slotted screw head in the center of the dial face. Using a small screwdriver, hold the screw stationary and at the same time use your finger to carefully move (push) the pointer to the correct temperature.Use your finger to push on the side of the wide short end of the pointer. If you push on the side of the narrow end of the pointer, it may bend. Push the pointer clockwise to move it to a higher temperature; push the pointer counterclockwise to move the pointer to a lower temperature.
5) After the recalibration process is completed,replace the plastic lens by gently pushing it back into the case using your thumbs.
Warning: Any improper adjustments that lead to malfunctioning of the thermometer will be at owner's responsibility.
