4. Setup
4.1 Charging the Device
The FD-90A-CO-PUMP is equipped with a rechargeable Lithium Ion battery. To charge, connect the provided USB cable to the device's micro-USB port (located on the side) and plug the other end into any standard USB power source (e.g., computer, wall adapter). The charging indicator on the display will show the charging status.
4.2 Attaching the Belt Clip and Sling
The device comes with a durable stainless steel belt clip, allowing for convenient hands-free carrying. A ring at the top of the device also allows for attachment of a sling or lanyard for added security, especially when working at heights or in dynamic environments.

4.3 Initial Calibration Check
Your device comes factory calibrated to USA NIST traceable standards. It is recommended to perform a fresh air zero calibration before each use to ensure optimal accuracy. Refer to the 'Operating Instructions' section for details on performing a zero calibration.
5. Operating Instructions
5.1 Power On/Off
- Power On: Press and hold the power button (usually the middle button) for a few seconds until the display illuminates. The device will perform a self-test.
- Power Off: Press and hold the power button until the device powers down.
5.2 Display Information
The digital display shows real-time CO concentration in parts per million (ppm), temperature, and current time. It also indicates battery level and alarm status.

5.3 Alarm Settings
The FD-90A-CO-PUMP features adjustable alarm thresholds for audio, visual (LED), and vibration alerts. These can be configured via the device's menu to suit specific safety requirements or local regulations. The device logs alarm events with a time stamp.
5.4 Using the Integrated Pump for Point Sampling
The integrated pump allows for active sampling, drawing air from a specific location through the stainless steel probe and silicone tubing. This is crucial for:
- Confined Space Entry: Sampling air in areas like manholes, tanks, or ducts before entry.
- Leak Detection: Pinpointing the source of CO leaks in HVAC systems, appliances, or exhaust vents.
- Remote Sampling: Obtaining readings from hard-to-reach or hazardous locations without exposing the user or the main detector unit to the environment.
To use the pump, attach the silicone tubing to the barb at the end of the stainless steel probe, and then attach the probe to the device's inlet. Activate the pump via the device's menu or a dedicated button (refer to the detailed user manual for specific button functions). The display will show a load indicator for the pump.

6. Maintenance
6.1 Calibration
Regular calibration is essential for maintaining the accuracy and reliability of your CO detector. The FD-90A-CO-PUMP supports both zero and span calibration options. It is recommended to perform a fresh air zero calibration daily or before each use. Full span calibration with certified calibration gas should be performed periodically (e.g., every 6-12 months) or as required by your industry standards. Refer to the detailed user manual for step-by-step calibration procedures.
6.2 Cleaning and Storage
Keep the device clean and free from dust and debris. Use a soft, damp cloth for cleaning the exterior. Do not use harsh chemicals or abrasive cleaners. Store the device in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
7. Troubleshooting
If you encounter any issues with your FD-90A-CO-PUMP, please refer to the following general troubleshooting tips:
- No Power: Ensure the battery is fully charged. Try charging the device for at least 2 hours.
- Inaccurate Readings: Perform a fresh air zero calibration. If issues persist, a full span calibration may be required. Ensure the sensor inlet is not obstructed.
- Pump Not Working: Check for kinks or blockages in the silicone tubing and probe. Ensure the pump is activated correctly via the device menu.
- Alarm Malfunction: Verify alarm settings in the device menu. If the alarm does not sound or vibrate when expected, contact customer support.
For more detailed troubleshooting steps and error codes, please consult the comprehensive user manual provided with your device or visit the FORENSICS DETECTORS support website.
