4. Setup

4.1 Charging the Device

Before initial use, fully charge the detector. Connect the provided USB charging cable to the device's USB port and plug the other end into a compatible USB power adapter. The battery indicator on the LCD display will show charging status. A full charge typically takes a few hours.

The device features a 1500mAh battery, offering extended operational time.

4.2 Initial Power On

Press and hold the power button (usually the middle button) for a few seconds until the LCD screen illuminates. The device will perform a self-test and then display the current gas concentration, time, and battery level.

5. Operating Instructions

5.1 Power On/Off

• To Power On: Press and hold the power button until the screen turns on.
• To Power Off: Press and hold the power button for approximately 3 seconds. The device will beep and display a countdown before shutting down.

5.2 Understanding the Display

The LCD display shows critical information:

• Gas Type: 'EX' indicates detection of explosive gases.
• Concentration: Displays the current gas concentration in LEL% (Lower Explosive Limit percentage).
• Time: Current time.
• Battery Indicator: Shows remaining battery life.

The LCD display with backlight ensures clear visibility of gas readings and device status.

5.3 Alarm Indications

When gas concentration exceeds preset thresholds, the device will activate three types of alarms:

• Visual Alarm: The alarm light (red LED) will flash.
• Audible Alarm: The buzzer will emit a loud sound.
• Vibration Alarm: The device will vibrate.

The detector provides comprehensive alarm indications through visual, audible, and tactile feedback.

5.4 Setting Alarm Thresholds

The device allows for custom adjustment of high and low alarm thresholds. This feature enables users to set specific alarm points based on environmental or industry safety standards, helping to prevent unnecessary alarms while ensuring critical alerts are triggered.

Users can customize alarm thresholds to suit specific safety requirements.

5.5 Data Records

The K-100A-EX automatically records operation and detection data, allowing users to review historical gas concentration levels and alarm events. This feature is useful for compliance, analysis, and safety audits.

The device automatically saves detection data for later review and analysis.

6. Maintenance

6.1 Cleaning

Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or sensor. Ensure the sensor opening is clear of debris.

6.2 Battery Care

To prolong battery life, avoid fully discharging the device frequently. Recharge the battery when the low battery alert is triggered. Store the device in a cool, dry place if not in use for extended periods, and recharge periodically.

6.3 Calibration

Regular calibration is crucial for maintaining the accuracy of the gas detector. The K-100A-EX supports both zero-point calibration and span calibration. Use the provided calibration cover for accurate calibration procedures.

Using the calibration cover ensures accurate and stable calibration results.

The device is equipped with functions for both zero-point and normal calibration.
