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.
