Product Introduction
Muscle & Fat Z2 Pro is an intelligent device that can quickly measure the thickness
of subcutaneous fat and muscle in multiple parts of the human body based on the
ultrasonic principle. It can help obese group, fitness group, women pursuing beauty,
diabetic group and other people to monitor the changes of subcutaneous fat
thickness and muscle thickness for a long time.
Muscle & Fat Z2 Pro consists of device and mobile application software
(hereinafter referred to as APP). The device is used to transmit and receive
ultrasonic signals, output the ultrasonic image data of the subcutaneous tissues after
signal transformation and a series of signal processing operation, and transmit the
image data to APP through Bluetooth. APP software is used to identify the fat
thickness from the ultrasonic image, analyze and automatically determine and
output the fat thickness value.

Selecting Measuring Parts
Click the menu “Measuring Parts” on the home page and select the function and
part to be measured in the pop-up panel.
Fat measurement: measure subcutaneous fat thickness; currently, five measuring
parts are supported: waist, abdomen, arm, thigh and calf.
Muscle measurement: measure muscle thickness; currently, four measuring parts
are supported: rectus abdominis, biceps brachii, rectus femoris and musculus
gastrocnemius.
* As mentioned above, there is no “abdomen” function in the intelligent fat reading measurement, and
“general” function only provides images but does not provide measurement; there is “abdomen” function
in the professionally manual measurement, and “general” function can measure and save the measurement
results.
* In visitor mode, select “Gender” before selecting the measuring part.

Fat Measurement -
Manual Measurement
Measurement Principle
The structure of skin and subcutaneous tissues
from top to bottom is: epidermis → dermis →
fat layer → muscle layer → other tissues
(visceral fat/ skeleton/internal organs, etc.).
The outer layer of the muscle is covered with
thick fascia, which separates the fat from the
muscle. Muscle & Fat Z2 Pro first collects the
ultrasonic image of the subcutaneous tissue,
then identifies the boundary between the fat
layer and the muscle layer through intelligent
recognition algorithm (intelligently automatic
reading measurement) or subjective judgment
of the operator (professionally manual
measurement), and calculates the distance
from the epidermis to the outer fascia of the
muscle to obtain the thickness of the
subcutaneous fat.

Measuring Methods and Steps
As described later.
Extrude the coupling agent with the size of
pistachio on the ultrasonic sensor, and
slide back and forth in the measuring area
to make the coupling agent evenly spread;
Place the device at the starting point and
keep it perpendicular to the skin, hold
down the measurement button and slide
gently on the skin at a constant speed, and
keep the ultrasonic sensor fit with the skin.
After image collection, click “Enter
Measurement” to adjust the ruler to
measure, and save the result.
Step 1: Determine the measuring
part
Step 2: Apply the coupling agent
Step 3: Slide against the skin
Step 4: Adjust the ruler to measure

Measuring Part - Waist
Waist measuring position:
− Standing posture
− Find the midpoint from the navel to the waist (point C as shown
in the figure), the area from 2cm next to point B as the starting
point to point A is the measurable area.
17

Measuring Part - Abdomen
Abdomen measuring position:
− Standing posture
− Slide to the right in the rectus abdominis area above the navel, with the
left rectus abdominis as the starting point;
− The bow shape on the image is the rectus abdominis, and the
subcutaneous fat layer is above the rectus abdominis;
18

Measuring Part - Upper Arm
Arm measuring position:
− Keep your upper arm level and forearm vertical;
− Find the midpoint between elbow and armpit (point B shown in the figure). Point B
is the starting point, and the area from point B to point A is the measurable area.
Tips:
Compared with the waist, the subcutaneous fascia of the arm is more and more complicated.
If it is found that there are more fascia directly under the arm, which interferes with the
measurement, it can be moved to the inner or outer side of the arm, and then slide it towards
the armpit. Users with soft meat may have difficulty controlling the sliding force, so you
can try a few times to measure correctly.
19

Measuring Part - Thigh
Thigh measuring position:
− Standing posture
− Find the midpoint between the iliac crest
and the upper edge of the knee (point B as
shown in the figure). The area 3cm above
and below point B is the measurement area;
slide from top to bottom;
Tips:
If there is more fascial interference at point B, move
a little to the lateral or medial side of the thigh.
