parameter. The display will alternately flash this mnemonic and the temperature value it expects to see.
8.Adjust the reference source to output a voltage equivalent to that generated by a “J” or “K” (OTC25 P) thermocouple at the temperature flashing on the display. (Allow reference to settle for 10 seconds before proceeding.)
9.Repeat Step 6 for this reference point.
10.Press the Parameter 
Key for 10 seconds or allow 60 seconds of inactivity.
11.Adjust the reference source to output a voltage equivalent to that generated by a “J” or “K” (OTC25 P) thermocouple at 32° F (0° C). Verify that (after settling), the OTC25 indicates a measured temperature of 32° F (0° C).
12.Repeat Step 11 for the upper reference point.

CLEANING INSTRUCTIONS
1.Remove power from the unit prior to any cleaning operation.
2.Use a cotton cloth to gently and sparingly apply isopropyl alcohol only. Do not use cleaners or other solvents as they may damage the unit.
3.Allow the unit to dry completely prior to reapplying power.
