Ijikọ Thermocouples
The K102 supports two K-type thermocouples. Connect your K-type thermocouple probes to the T1 and/or T2 input jacks located at the top of the device. Ensure a secure connection for accurate readings.
Ntuziaka ọrụ
Ịgbanyụ/ Gbanyụọ
Pịa O button to turn the thermometer ON. Press and hold the O button for approximately 2 seconds to turn it OFF.
Na-ewere nha okpomọkụ
- Ensure thermocouples are properly connected to the T1 and/or T2 inputs.
- Turn on the device using the O bọtịnụ.
- The display will show the current temperature readings for T1 and T2 (if both are connected).
- Place the thermocouple probe(s) at the desired measurement point.
- Allow a few moments for the reading to stabilize on the display.
Switching Temperature Units (°C/°F)
Pịa ° C/° F button to toggle between Celsius (°C) and Fahrenheit (°F) temperature scales.
Ọrụ MAX/MIN
Pịa MAX/MIN button to cycle through the maximum, minimum, and current temperature readings recorded since the device was powered on or the function was last reset. To reset the MAX/MIN values, press and hold the MAX/MIN button until the display clears or resets.
Jide Ọrụ
Pịa Jide button to freeze the current temperature reading on the display. This is useful for recording readings in unstable environments. Press it again to release the hold and resume live readings.
Relative Measurement (REL)
The relative measurement function allows you to set the current reading as a reference point (zero) and display subsequent measurements as a deviation from this reference. Press the REL button to activate this mode. The display will show '0.0' and then subsequent readings will be relative to this zero point. Press it again to exit relative mode.
Okpomọkụ dị iche (T1-T2)
When two thermocouples are connected to both T1 and T2 inputs, the device can display the temperature difference between T1 and T2. This mode is typically accessed by cycling through display options using a dedicated button or automatically displayed alongside T1 and T2 readings.
Nlekọta
Nhicha
Jiri nwayọ hichapụ ngwaọrụ ahụ, dị ntakịrị damp cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the device is completely dry before storage or further use.
Ngbanwe batrị
When the low battery indicator appears on the display, replace the 9V battery as described in the "Installing the Battery" section under Setup.
Nchekwa
Store the thermometer in a cool, dry place, away from direct sunlight and extreme temperatures. Remove the battery if storing for extended periods (e.g., more than one month) to prevent leakage and damage to the device.
