One end of the high sensitive probe contacts the pet; the other connector end connects to the main machine.

1. Connect sensor to the host and power on. Align point 1 and point 2 for correct connection. Pull out by pinching the lined area.
2. Apply ultrasonic couplant to the sensor top and the animal's test area.
3. Place sensor on the area and move slowly until the strongest pulse is heard.
4. Using earphones automatically mutes the loudspeaker for clearer Doppler sound.
5. If the power light is off, please charge the host.

1. Inflation: Close the valve and slowly press the gasbag.
2. Deflation: Open the valve and gently press the gasbag until the cuff is fully deflated.

1. Cut fur on the volar pad (especially beneath the first toe). Apply couplant on the mid-line of the foot.
2. Apply couplant on the probe. Move the probe on the mid-line until a "so-so-so" sound is heard.
3. For outpatient exams, use 3 staff members: one to calm the pet, one for the probe, and one for the meter. For surgery, one person can monitor every 5-10 minutes.
4. Place the cuff above the forelimb wrist (proximate to the heart). Ensure the indicator is within the circumference range to avoid inaccurate readings.
5. Inflate until the sound stops, then add 20mmHg more. Open the valve slowly to record systolic pressure.
6. Diastolic pressure can be recorded during slow deflation, though it is harder to detect due to Doppler theory.
7. In winter, use a heated room. If the temperature is below 10°C, the pulse may be hard to hear.
8. Usual range for cats and dogs: 110mmHg to 160mmHg.

• Outpatient: Do not fasten the probe with tape; hold it with a finger to easily reposition if the pet moves.
• Anesthesia: Fasten the probe with adhesive tape for continuous monitoring.
• Apply slight pressure to ensure the probe makes good contact with the skin.
• Use earphones to hear pulses clearer and avoid scaring the pet.
• Adjust speaker volume appropriately; too loud may miss subtle sounds.
• Keep the pet's leg straight to avoid influencing blood flow.
• Measure 6-7 times until the pet calms; stable values are the most accurate.

Turn off power after use. Protect the probe from crashes or collisions as it contains expensive chips.

Only use ultrasonic couplant. Do NOT use ECG gel, baby oil, or other oils, as they corrode the probe.

Charge or change the battery when the power light dims or the speaker stops working.

• Probe Frequency: 9 MHz
• Battery: DC 7.4V 2600mAh lithium battery
• Speaker: 4Ω 1W
• Earphone: 3.5mm Plug, dual rack 270Ω
• Host Dimensions: 160mm(L) * 90mm(W) * 40mm(H)
• Package Dimensions: 37mm(L) * 31mm(W) * 14mm(H)

• Wipe off couplant with a napkin after use.
• Use alcohol swabs to gently swipe for sterilization.
• Consult the manufacturer before using other disinfectants.

Prevent water from entering the body when cleaning the host.
