The following messages can appear in the numerics window.

displays the pressure waveform, but to protect against erroneous readings, the
pressure waveform scale is not displayed. To remove this message, zero the
transducer.

ZEROED. This message appears after the zero value has been accepted. It remains
for eight seconds and is replaced by the current pressure values.
ZERO REJECTED (or REJECT). Unable to establish a zero reference value. The
message remains until the CANCEL button is pressed.
