every time, please contact the manufacturer because of the poor connection of the screen line or or the failure
of the LCD screen.

Check if the cable plug is properly inserted. If there is no ECG wave, please check if the cable is
disconnected.

Check the cuff for leakage. Check if the air hose connector is tightly inserted into NIBP socket on front panel and
if the setting for animal type is compatible with the type of cuff. If there still is no result, please contact the
manufacturer.


Check if the light in the SpO
2
sensor blinks. (Attention: DO NOT look at the blinking light directly, as it
might cause injury to your eyes).

Check if the SpO

probe is securely connected to SpO
2
port on the front panel.

Examine the body of the animal for any abnormality where the SpO

If there still is no result, please contact the manufacturer.
15.8 Measure Result of EtCO
2
is Low (Optional)

Ensure that CO
2
module is correctly calibrated (At least one effective calibration is done prior to shipment).
Attention: calibration without use of standard gas or calibration to the wrong standard gas concentration will
result in reading error. In this case the machine will not give any warning. It is suggested to have the machine
calibrated by a third-party authoritative organization or by the manufacturer.

For by-pass module, check the full length of the air tube from the inlet of main tube (or sampling tube) to the
dewatering bottle to ensure that the connector is securely tightened, or if there is hole in the tube, or if the
dewatering bottle is damaged or cracked.

For mainstream module, check if the air tube is tightly connected to the main tube and if the sensor is
clamped to the correct position on the air tube adapter. When changing the adapter or a new animal, please
zero the scale before use (refer to 6.8.6)
If the problem remains, please contact the manufacturer.
