5.2 WiFi Connection (If Applicable)
Refer to the separate Kamoer app manual for detailed instructions on connecting your FX-STP2 to your home WiFi network and configuring it via the mobile application. This typically involves downloading the Kamoer app, creating an account, and following the in-app pairing process.
6. Operating Instructions
6.1 Initial Start-up
Once powered on, the pump will typically display its current status. If connected via WiFi, you can control it through the Kamoer app. Manual controls may also be available on the unit itself for basic functions.
6.2 Adjusting Flow Rate
The flow rate can be adjusted from 1 ml/min to 120 ml/min. This adjustment is primarily done through the Kamoer mobile application. Navigate to the pump's settings within the app and use the interface to set your desired flow rate. The pump will begin dosing at the new rate immediately.
6.3 Calibration
Regular calibration ensures accurate dosing. To calibrate:
- Place the outlet tubing into a measuring cylinder.
- Initiate the calibration process via the Kamoer app (or pump controls if available).
- The pump will dispense a set volume (e.g., 100 ml).
- Measure the actual volume dispensed and enter this value into the app.
- The pump will adjust its internal settings for improved accuracy.

7. Maintenance
7.1 Tubing Replacement
The PharMed peristaltic tubing has a long lifespan but will eventually require replacement due to wear. Signs of wear include reduced flow accuracy, leaks, or visible damage to the tubing.
- Disconnect Power: Always unplug the pump before servicing.
- Access Pump Head: Open the pump head cover (refer to diagrams in the app or product documentation if unsure).
- Remove Old Tubing: Carefully detach the old tubing from its connectors and rollers.
- Install New Tubing: Insert the new PharMed tubing, ensuring it is correctly seated within the pump head and secured by the rollers.
- Close Pump Head: Securely close the pump head cover.
- Recalibrate: After replacing tubing, it is recommended to recalibrate the pump for optimal accuracy.
