NIBP250 User’s Guide
6. Troubleshooting
6.1. Tail Pulse signals are not regular.
The animal may be under stress, resulting in excessive tail movement. Remove the animal from the
RESTRAINER holder until it calms down before continuing with the experiment.
The tail may not be sufficiently warmed or cooled down. Put the animal in the Tail Heater Chamber and
repeat the heating process. Make sure the tail temperature is 32
C.
Tail Cuff sizing may be incorrect. Check Table 5 on the following page for sizing descriptions.
Tail Cuff Sensor position may be incorrect. Try re-attaching the sensor in a different location on the tail.
The optimal location is between the mid-point of tail and base of tail (spinal column).
6.2. Compressor runs continuously
Immediately Turn off the NIBP250 system.
Remove the Tubing from the Cuff connector on the rear panel of NIBP250
Turn the system back on.
Close the air outlet by pressing the finger on the Cuff output and press the “Start” button. The compressor
will work for a few seconds and stop (please inform BIOPAC if the Compressor does not stop). The
pressure chart should be viewable on the screen.
If the Compressor stops automatically, it means that the system is working normally.
6.3. There is leakage from the tubing and Tail Cuff Sensor connections.
Make sure the tubing connections are securely attached.
