Key Functions & Controls

 * Power Button (Red): Long-press powers on/off; toggles auto-power-off (APO).

 * ADJ / TYPE: Selects thermocouple type (K, J, T) and enters temperature calibration offset mode (-9°C to +9°C).

 * REC / HOLD: Freezes screen readings or long-presses to start recording data logs.

 * MAX / MIN: Cycles between Maximum, Minimum, and Average temperature values.

 * °C / °F: Toggles temperature measurement units.

 * High/Low Alarm: Visual and audible alerts when temperatures cross set limits.

Primary Uses

 * Multi-Point HVAC Systems: Simultaneously logging supply air, return air, evaporator coils, and ambient temperatures.

 * Complex Thermal Mapping: Monitoring multi-zone industrial ovens, furnaces, heat-treatment processes, and circuit board hotspots.

 * Automotive & Engine Testing: Tracking multiple exhaust ports, cooling fluids, and intake manifolds during engine runs.

 * R&D Laboratory Logging: Long-term continuous temperature recording via USB connection directly to a PC.
