When lead off, the waveform will not be displayed. Pressing "record" button is ineffective. Please
check the loose electrodes or electrode leads according to the prompt message and reconnect them.

①
When the lead wires are not connected to the animal or the instrument stably, ECG signals can
not be transmitted correctly, this message will be displayed for reminding;
②
When the polarization voltage exceeds the limit value, the message will be displayed for
reminding.

If the “electrodes off” message is shown, handle it according to the following method:
①
Press “reset” button to eliminate the influence of the polarization voltage to amplifier. It will get
the amplifier back to normal quickly;
②
If pressing “reset” button does not eliminate the alarm, check the corresponding electrode and
its connection.
If “lead off” alarm is displayed, it means the electrocardiograph is inoperable due to anoverload.
If the waveform become straight line, it means the electrocardiograph is inoperable due to
saturation of any part of amplifier.
The Isoelectric segments within the QRS are included in the Q-, R- or S-waves. The isoelectic
parts(I-wave_ after global QRS-oneset or before global QRS-offset(K-wave) are not included in the
duration measurement of the respective adjacent waveform.
4.4 Battery Installation
See Figures below for installation:
1. Turn the electrocardiograph upside-down, unscrew and remove the battery door as A enclosed;
