Key Features

• 2-in-1 Design: Combines non-contact infrared (IR) for surface temperature and a foldable thermocouple probe for internal temperature.
• Wide Temperature Ranges:
  • Infrared: -67 to 572°F (-55 to 250°C)
  • Probe: -67 to 626°F (-55 to 330°C)
• HACCP Check Function: Clearly indicates if food is in a dangerous (4~60°C / 40~140°F) or safe temperature zone.
• High Accuracy: Infrared Accuracy ±1.8°F (32-149°F), Probe Accuracy ±0.9°F (0.5°C).
• Adjustable Emissivity: User-adjustable from 0.10 to 1.00 in 0.01 steps (factory preset to 0.95).
• Measurement Modes: Includes Minimum, Maximum, and Lock modes for continuous scanning.
• Dual Display: Shows both IR and probe readings simultaneously.
• IP65 Protection: Provides protection against dust and low-pressure water jets.
• Portable Design: Ultra-thin, fits into a shirt pocket, comes with a storage case.
• Auto Power Off: Conserves battery life.

Setup

1. Battery Installation

The AMTAST AMT206 thermometer requires one Lithium battery for operation. Please note that batteries are not included in the package due to aviation security regulations.

1. Locate the battery compartment on the back of the device.
2. Open the battery cover.
3. Insert the Lithium battery, ensuring correct polarity (+/-).
4. Close the battery cover securely.

2. Initial Power On and Unit Selection

Press any button to power on the device. The default temperature unit is usually Fahrenheit (°F). To switch between Celsius (°C) and Fahrenheit (°F):

• With the device on, press the Mode button repeatedly until the desired unit is displayed.

3. Emissivity Adjustment

Emissivity (ε) is a measure of an object's ability to emit infrared energy. Different materials have different emissivity values. The factory preset is 0.95, which is suitable for most organic materials and painted surfaces. For highly reflective surfaces, you may need to adjust the emissivity for accurate IR readings.

• Press the Mode button until 'ε' appears on the display.
• Use the Scan or Probe buttons to adjust the emissivity value from 0.10 to 1.00 in 0.01 steps.
• Press Mode again to confirm and exit.

Operating Instructions

1. Infrared (IR) Temperature Measurement

The IR function measures the surface temperature of an object without contact.

1. Ensure the probe is folded into the device.
2. Point the infrared sensor towards the target object.
3. Press and hold the Scan button. The display will show the real-time surface temperature.
4. Release the Scan button to hold the reading on the display.

Distance-to-Spot Ratio (D:S): The AMT206 has a D:S ratio of 2.5:1. This means that at a distance of 2.5 units, the measurement spot diameter is 1 unit. For example, if you are 2.5 inches away from the target, the measurement area will be 1 inch in diameter. Ensure the target is larger than the spot size for accurate readings.

2. Probe Temperature Measurement

The foldable probe measures the internal temperature of liquids or semi-solid materials.

1. Unfold the stainless steel probe from the side of the device.
2. Insert the probe into the center of the food or liquid you wish to measure. Ensure the probe tip is fully immersed and not touching bones or the bottom of the container.
3. The display will automatically switch to probe mode and show the internal temperature.
4. Wait for the reading to stabilize (usually a few seconds).

3. Measurement Modes (Min/Max/Lock)

The thermometer offers various modes to enhance measurement utility:

• Minimum (MIN) Mode: Displays the lowest temperature recorded during a continuous scan.
• Maximum (MAX) Mode: Displays the highest temperature recorded during a continuous scan.
• Lock Mode: Allows for continuous temperature scanning without holding the scan button.

To cycle through these modes, press the Mode button after initiating a scan or with the probe extended. The display will indicate the active mode.

4. HACCP Check

The HACCP (Hazard Analysis and Critical Control Point) check feature provides a visual indication of food safety zones.

• The display will show indicators for safe and dangerous temperature zones.
• A specific indicator will light up to show if the measured temperature falls into the safe zone (below 4°C/40°F or above 60°C/140°F) or the dangerous zone (4~60°C / 40~140°F).

Maintenance

1. Cleaning

To ensure hygiene and proper functioning, clean the thermometer regularly.

• Wipe the body of the thermometer with a damp cloth. Do not immerse the device in water.
• For the stainless steel probe, wipe it clean with a mild detergent solution and rinse thoroughly before and after each use, especially when measuring food.
• Do not use abrasive cleaners or solvents, as they may damage the device.

2. Storage

When not in use, store the thermometer properly to protect it from damage.

• Fold the probe back into its housing.
• Store the thermometer in its provided protective case.
• Keep the device in a cool, dry place, away from direct sunlight and extreme temperatures.

3. Battery Replacement

Replace the battery when the low battery indicator appears on the display or the device fails to power on.

• Follow the battery installation steps outlined in the Setup section.
• Dispose of old batteries according to local regulations.
