6.

Select Zero Probe. The unit displays the message

ZEROING

in the IBP Channel’s numeric

display.

7.

The message ZEROED appears in the IBP channel’s numeric display.

8.

Close the transducer’s stopcock.

9.

If the unit was unable to zero the transducer, the message ZERO REJECTED appears in the
IBP channel’s numeric display. The unit will not display pressure values for the IBP channel
until it has successfully zeroed the transducer and established an acceptable zero reference.

Check that the unit is open to atmospheric air and that it is properly connected to the unit, then
try zeroing the transducer again. The X Series unit will not zero the transducer if it detects
pulsation in the pressure channel, if there is too much noise in the signal, or if transducer’s
offset is too great.

If you cannot zero the transducer after several attempts, replace the transducer or the transducer
cable.

Rezeroing a Transducer

You can re-zero a transducer at any time by opening the transducer stopcock to atmospheric air.

If the unit accepts the new zero reference value, the unit displays pressure values that are based
on that value and adjusts the waveform according to the new scale.

Warning!

If you attempt to zero an IBP channel after the channel has been successfully zeroed
and is currently monitoring a pressure waveform, the unit will display the message,

ZERO REJECTED

, in the IBP channel’s numeric window. This message will preempt

the display of the valid invasive pressure numerics.
