Сетуп

1. Инсталација батерије

The Benetech GM321 requires two AAA batteries (included). To install the batteries:

1. Пронађите поклопац одељка за батерије на дршци термометра.
2. Пажљиво повуците поклопац батерије надоле да бисте отворили одељак.
3. Уметните две ААА батерије, водећи рачуна о исправном поларитету (+/-) као што је назначено унутар одељка.
4. Чврсто затворите поклопац батерије док не кликне на своје место.

2. Прво укључивање

Once batteries are installed, the device is ready for use. Simply press the trigger to power on the thermometer and begin measuring.

Упутство за употребу

1. Basic Temperature Measurement

To measure the surface temperature of an object:

1. Point the infrared thermometer at the target object.
2. Press and hold the trigger. The laser pointer will activate, indicating the measurement area.
3. The temperature reading will be displayed instantly on the LCD screen. Release the trigger to hold the reading.

2. Unit Conversion (°C/°F)

Да бисте прелазили између Целзијуса (°C) и Фаренхајта (°F):

• Када је уређај укључен, притисните тастер ° Ц/° Ф button located below the display.
• The unit on the display will change accordingly.

3. Mode Selection (MAX/MIN/Ambient/Emissivity)

The thermometer offers multiple measurement modes. Press the МОДЕ дугме за прелазак кроз њих:

• ДРЖАТИ: Data Hold (default after releasing trigger).
• МАКС: Displays the maximum temperature recorded during continuous measurement.
• МИН: Displays the minimum temperature recorded during continuous measurement.
• АТ: Measures the current ambient temperature.
• ЕМС: Emissivity adjustment mode.
• ЦАЛ: Self-calibration mode.

4. Emissivity Adjustment

Emissivity (EMS) is crucial for accurate temperature measurement of different surfaces. The GM321 allows adjustment from 0.1 to 1.0, with a default of 0.95. To adjust emissivity:

1. Притисните тастер МОДЕ дугме док се на екрану не појави „EMS“.
2. Користите горе (▲) и доле (▼) buttons to adjust the emissivity value.
3. Refer to the table below for common material emissivity values.

Figure 6: Emissivity adjustment and common material values.

5. Distance to Spot Ratio (D:S)

The GM321 has a Distance to Spot (D:S) ratio of 12:1. This means that at a distance of 12 inches, the measurement spot size will be 1 inch. To ensure accurate readings, measure from a distance where the target object completely fills the spot size.

Одржавање

1. Чишћење

Да бисте очистили термометар, нежно обришите површину меком,amp тканина. Не користите абразивна средства за чишћење нити урањајте уређај у воду.

2. Замена батерије

When the low battery indicator appears on the display, replace the two AAA batteries following the installation steps in the Setup section.

Решавање проблема

1. Нетачна очитавања

• Емисивност: Ensure the emissivity setting is correctly adjusted for the material being measured. Refer to the Emissivity Adjustment section.
• Удаљеност: Maintain the correct distance to spot ratio. Ensure the target completely fills the measurement spot.
• сметње: Avoid measuring through steam, dust, or highly reflective surfaces. These can significantly affect accuracy.

2. Self-Calibration

The device supports self-calibration between -1.5°C and +1.5°C to fine-tune accuracy. Access the CAL mode via the MODE button and use the Up/Down arrows to adjust.

Спецификације

Важне информације о безбедности

• NOT FOR HUMAN USE: This infrared thermometer is designed for industrial and scientific applications, as well as for measuring surface temperatures of food, oil, and water. It is не намењен за мерење температуре људског тела.
• ЛАСЕРСКА БЕЗБЕДНОСТ: Do not stare directly into the laser beam. Avoid pointing the laser at people or animals.
• AVOID INTERFERENCE: Steam and dust can interfere with the accuracy of infrared thermometers. Ensure a clear line of sight to the target surface.
