12.Wait for U.U.T. readout to stabilize, then press HOLD key once, and wait a few seconds. U.U.T. should read 32.0°F ±0.5°F, type J.

13.Set calibrator output to 1400°F, type J.

14.Wait for U.U.T. readout to stabilize, then press HOLD key once, and wait a few seconds. U.U.T. should read 1400.0°F ±1.0°F, type J.

NOTE: On Model HH-22, go to step 21 to complete calibration. On Models HH-21and HH-23, continue calibration at step 15.

15.Replace type J cable with Type T.

16.Set calibrator output to 32°F, type T.

17.Wait for U.U.T. readout to stabilize, then press HOLD key once, and wait a few seconds. U.U.T. should read 32.0°F ±0.5°F, type T.

18.Set calibrator output to 750°F, type T.

19.Wait for U.U.T. reading to stabilize, then press HOLD key once, and wait a few seconds. U.U.T. should read 750.0°F ±1.0°F, type T.

20.Press HOLD key one last time. Wait for HOLD annunciator to show on readout. (Indicates that calibration data is stored in EEPROM.)

21.Carefully remove battery cover while holding battery in place. Loss of battery power at this time will cause loss of calibration data.

22, Remove back cover while holding battery in place.

23.Re-install shorting-plug J1 to write-protect EEPROM.

24.Turn off U.U.T. Replace rear cover and battery cover. Calibration is com- plete.

2. DISASSEMBLY INSTRUCTIONS

Before opening the case, remove all input/output connections. This includes input sensors, calibration cables, and the optional battery charger.

Turn the instrument face down, and remove the three Phillips head screws from the rear cover. Lift off the rear cover. The circuit board can be lifted from the front case after removal of the hexagonal-standoff.

NOTE: Be sure to keep the case face down during this last step. Otherwise, the LCD and its associated hardware may fall free and break.
