This manual provides detailed instructions for the proper use, setup, and maintenance of your Traceable® Digital Thermometer with Bottle Probe. This precision instrument is designed for accurate temperature monitoring, particularly in environments requiring stable temperature readings such as refrigerators, freezers, and water baths. It features a sealed bottle probe that mimics the temperature of stored liquids, preventing false alarms from temporary door openings.
Each unit comes with a NIST-traceable certificate from an ISO/IEC 17025:2017 (1750.01) accredited calibration laboratory, ensuring accuracy and reliability.

รูปที่ 1 : ด้านหน้า view of the Traceable Digital Thermometer with Bottle Probe. The display shows current, minimum, and maximum temperatures. The bottle probe is connected via a cable.
Figure 2: The Traceable Digital Thermometer with its bottle probe positioned inside a refrigerator, demonstrating its typical application for stable temperature monitoring.
The Traceable Digital Thermometer is equipped with a triple-display, allowing simultaneous viewing of the current, minimum, and maximum temperatures. The sealed bottle probe is filled with a non-toxic glycol solution, which buffers temperature changes, providing a more accurate representation of the temperature of stored contents rather than ambient air fluctuations.
- Triple-Display: Shows high, low, and current temperature simultaneously.
- หน่วยความจำขั้นต่ำ/สูงสุด: Stores minimum and maximum temperatures until cleared.
- Bottle Probe: Sealed bottle filled with glycol solution for stable temperature readings, ideal for refrigerator/freezer monitoring.
- NIST-Traceable Certificate: Ensures accuracy and compliance with regulatory requirements.
- ตำแหน่งที่หลากหลาย: Features a fold-out stand for desktop use, magnetic strips for metal surfaces, and a wall-mount keyhole.
การติดตั้งและการตั้งค่า
- การติดตั้งแบตเตอรี่: The thermometer requires one AA battery (included). Open the battery compartment on the back of the unit and insert the battery, observing polarity.
- การวางตำแหน่งโพรบ:
- Place the bottle probe inside the environment you wish to monitor (e.g., refrigerator, freezer). Ensure the probe is positioned where it will accurately reflect the temperature of the contents.
- Route the probe cable carefully to avoid pinching or damage.
- การจัดวางหน่วย:
- Use the fold-out stand to place the unit on a flat surface.
- Utilize the magnetic strips on the back to attach the unit to a metal surface (e.g., refrigerator door).
- Hang the unit on a wall using the keyhole slot.
- เปิดเครื่องครั้งแรก: The unit should power on automatically once the battery is installed. The display will show the current temperature, along with the minimum and maximum recorded temperatures since the last reset.

คำแนะนำการใช้งาน
ฟังก์ชั่นการแสดงผล
The thermometer's display shows three temperature readings simultaneously:
- อุณหภูมิปัจจุบัน: The real-time temperature reading from the bottle probe.
- MIN Temperature: The lowest temperature recorded since the last memory clear.
- MAX Temperature: The highest temperature recorded since the last memory clear.
ปุ่มฟังก์ชั่น
| ปุ่ม | การทำงาน |
|---|---|
| หน่วยความจำที่ชัดเจน | Press to clear the stored MIN and MAX temperature readings. The display will update with the current temperature as the new MIN/MAX. |
| โหมด | Toggles between Celsius (°C) and Fahrenheit (°F) temperature units. |
| สวิตช์เปิด/ปิดนาฬิกาปลุก | Activates or deactivates the audible alarm function. When activated, the alarm will sound if the temperature goes outside the set high/low alarm limits. |
| RESET (on back) | A small button on the back of the unit (often recessed) used to perform a hard reset of the device, typically requiring a pointed object like a paperclip. This will clear all settings and memory. |
| LO/HI (on back) | Buttons on the back of the unit used to set the low and high temperature alarm limits. Refer to the alarm setting section for details. |
Setting Alarms (Optional)
The thermometer can be configured to sound an alarm if the temperature exceeds or falls below user-defined limits. The alarm setting buttons (LO and HI) are located on the back of the unit.
- Ensure the ALARM ON/OFF switch is in the OFF position before setting limits.
- กดปุ่มค้างไว้ LO button on the back of the unit. The LO temperature will flash. Use the โหมด button on the front to adjust the desired low alarm limit. Release the LO button to set.
- กดปุ่มค้างไว้ HI button on the back of the unit. The HI temperature will flash. Use the โหมด button on the front to adjust the desired high alarm limit. Release the HI button to set.
- Once limits are set, slide the เปิด / ปิดนาฬิกาปลุก switch to the ON position to activate the alarm.
- If the temperature goes outside the set range, the alarm will sound. To silence the alarm, slide the ALARM ON/OFF switch to OFF.

การบำรุงรักษาและการดูแล
- การทำความสะอาด: Wipe the unit and probe with a damp cloth. Do not immerse the main unit in water. The bottle probe is sealed and can be wiped clean.
- การเปลี่ยนแบตเตอรี่: When the display becomes dim or erratic, replace the AA battery. Ensure proper polarity.
- พื้นที่จัดเก็บ: Store the thermometer in a dry environment away from extreme temperatures when not in use for extended periods.
- การสอบเทียบ: This thermometer comes with a NIST-traceable certificate. For continued accuracy and compliance, periodic re-calibration by an accredited laboratory is recommended, especially in regulated environments.
การแก้ไขปัญหา
| ปัญหา | สาเหตุที่เป็นไปได้ | สารละลาย |
|---|---|---|
| ไม่มีจอแสดงผลหรือจอแสดงผลมืด | แบตเตอรี่หมดหรืออ่อน; ติดตั้งแบตเตอรี่ไม่ถูกต้อง | Replace the AA battery, ensuring correct polarity (+/-). |
| การอ่านที่ไม่ถูกต้อง | Probe not properly placed; probe damage; unit malfunction. | Ensure the bottle probe is fully immersed in the monitored environment. Check the probe cable for visible damage. If issues persist, contact customer support. |
| นาฬิกาปลุกไม่ส่งเสียง | Alarm switch is OFF; alarm limits not set correctly. | Slide the ALARM ON/OFF switch to ON. Verify that the LO and HI alarm limits are set to the desired range. |
| MIN/MAX readings not clearing | MEMORY CLEAR button not pressed firmly or unit malfunction. | Press the MEMORY CLEAR button firmly. If it still doesn't clear, try a hard reset using the RESET button on the back. |
