suitable for mice. The pressure is measured by way of an internal pressure
transducer. Output is from the ‘Pressure Output’.
Pulse Input Connector
The pulse transducer is attached here. The signal is amplified and filtered
inside the NIBP Controller. Output is from the ‘Pulse Output’.
Filter Switch (Pulse Range)
This three position switch adjusts the filtering of the pulse signal. Details of
the frequency response are in Appendix B. For mice, use the 240–600 BPM
setting. For rats, 90–420 BPM is usually appropriate.
Start/Stop Button
The NIBP Controller measurement cycle is started by pushing the Start/Stop
button. This begins an inflation and deflation cycle. To stop the measurement
cycle (during either inflation or deflation) push the button again. This will
stop the cycle and immediately deflate the cuff.

C Input and Output Sockets
The NIBP Controller is designed to receive power and control signals from an
ADInstruments PowerLab. These are supplied by an ‘I
2
C Bus’ (a ‘bus’ is
simply information-transmission circuitry such as cables and connectors).
These I
2
C sockets allow many front-ends to be used independently with one
PowerLab. The I

C Input socket of the NIBP Controller connects to the I
