Rho Cuvette Tab - Millar MPVS Ultra User Manual

1 mV Cal
This button outputs a one second 1 mV cal signal. The signal can be used to calibrate the
user's data acquisition system or monitor. Note that since the ECG circuit has a high-pass
filter to eliminate DC offset, the output signal will appear as an initial upward pulse and
then a downward pulse. This is an ECG circuit's response to a square wave.
The ECG output is scaled at 2V / 1 mV.
Notch Filter
The MPVS Ultra contains a built-in notch filter on the ECG circuit to remove 50Hz and
60Hz noise. To turn this filter on, select "On" and to turn it off, select "Off".
ECG Input
The ECG Input allows the user to choose the source of the ECG input signal.
The MPVS Ultra can record an internal ECG signal from the electrodes on the P-V
catheter. To record this signal select Internal Catheter.
The MPVS Ultra can also be used as a bioamplifier for an external ECG source. To
choose this option, select External Source. The input for this signal is the ECG connector
on the front panel of the hardware.
