SYSTEM INFORMATION window
The SYSTEM INFORMATION window lists software revisions, current status for the
ERT Module and other useful information. The window will automatically close after
several seconds. Click the “Hold Open” button to keep the window visible.
ERT Module status includes the 50Hz/60Hz notch filter setting, battery voltage, ECG
and temperature lead status and offset voltage.
The ERT Module operates on 5VDC. But to display both positive and negative signals
the zero point is offset to 2.5V. Any additional offset appears in this measurement and
can affect the ECG. If the offset gets too close to zero or 5V, the software flat lines the
ECG waveform and issues a lead off warning. The offset can deviate from 2.5V if
needle electrodes are inserted in animal’s muscle or if the temperature probe is
defective (refer to Chapter 4).
The IBP Module status includes the modules power source (12V or internal battery) and
status of the internal battery charger.
