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 re f e re n c e
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.
