Page 8: Safety Notices And Information
Preparation for Use Safety Notices and Information Symbols and Terms Safety Notices denote hazards. They indicate an operating procedure, instruction, or practice that, if not correctly performed or followed, could result in damage to equipment, or injury or death to personnel. Do not proceed beyond a Safety Notice until all conditions and instructions are fully understood and complied with. - Page 9 Preparation for Use Do not attempt to measure temperatures beyond the range of the temperature probe. Probe damage or personal injury could result from exceeding a probe’s maximum temperature rating. CAUTION RISK OF INCORRECT READING Do not use when AC or DC voltages in excess of 1V exist between thermocouple channels (on instruments with more than one channel).

Service Information 4. S ERVICE NFORMATION Inspection and Cleaning To extend the life of the instrument, inspect and clean the instrument regularly. Inspect the instrument for any significant abrasions, cuts, cracks, dents, or other signs of damage on the case, keypad, and display lens. Inspect the connectors for breaks, dirt, or corrosion. Ensure all screws are securely fastened, and if equipped, that the tilt stand/magnet/hanger is in good condition and locks into position properly. -
Page 24: Alignment Procedure
Service Information Connect the opposite end of the Thermocouple Cable (or the single-connector end of the Split Thermocouple Cable) to the Thermocouple Calibrator thermocouple output. 10. Set the Thermocouple Calibrator thermocouple type to the desired thermocouple type. 11. Allow at least five minutes for this connection to stabilize. 12. - Page 25 Service Information Offset Ch. 1 0.0 °C Offset Ch. 2 (HH912T only) 0.0 °C Other thermocouple types may be used in this procedure as desired. For instance, if the UUT is used primarily with Type J applications, Cold Junction Compensation may be aligned using Type J.
