- Display: Shows temperature readings for T1, T2, and differential (T1-T2).
- Power Button (O): Turns the device ON/OFF.
- MAX/MIN Button: Toggles between maximum, minimum, and current readings.
- HOLD Button: Freezes the current display reading.
- REL Button: Activates relative measurement mode.
- °C/°F Button: Switches between Celsius and Fahrenheit temperature units.
- T1/T2 Inputs: Connect K-type thermocouples.

Setup
Installing the Battery
- Locate the battery compartment cover on the back of the device.
- Slide the cover downwards to open it.
- Insert a new 9V battery, ensuring correct polarity (+/-) as indicated inside the compartment.
- Replace the battery compartment cover by sliding it back into position until it clicks securely.

Connecting 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.
Operating Instructions
Powering On/Off
Press the O button to turn the thermometer ON. Press and hold the O button for approximately 2 seconds to turn it OFF.
Taking Temperature Measurements
- Ensure thermocouples are properly connected to the T1 and/or T2 inputs.
- Turn on the device using the O button.
- 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)
Press the °C/°F button to toggle between Celsius (°C) and Fahrenheit (°F) temperature scales.
MAX/MIN Function
Press the 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.
HOLD Function
Press the HOLD 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.
Differential Temperature (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.
Maintenance
Cleaning
Wipe the device with a soft, slightly 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.
Battery Replacement
When the low battery indicator appears on the display, replace the 9V battery as described in the "Installing the Battery" section under Setup.
Storage
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.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed battery. | Check battery polarity or replace with a new 9V battery. |
| Inaccurate readings. | Faulty thermocouple, poor connection, or device needs calibration. | Check thermocouple connection. Test with a known good thermocouple. Refer to calibration instructions (if provided separately) or contact support. |
| "OL" or "---" displayed. | Temperature out of range, open circuit thermocouple, or faulty probe. | Ensure temperature is within the specified range (-200 to +1370 °C). Check thermocouple for damage or proper connection. Replace faulty probe if necessary. |
