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.

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.
