keys
to choose “Trace”, press
key again, the cursor will show “+”;
3.
Press direction keys to move the “+” mark to desired position, press
key to set the “+” mark
position as the starting point of the measurement;
4.
Press direction keys to move the“+” mark to the end point of the measurement. At the same time, a
locus appears in the direction of operation between the two measurement marks. The measured
circumference value is displayed automatically at the built-in mark “C: 00000mm” on the right
part of the screen. Press
key to display at the built-in mark “A: 00000mm
2
” the value of the
measured area formed by measurement line enclosure;
5.
Press
key, the measurement methods are showed in the lower left of the screen, continue to
choose “Trace” to measure;
6.
Repeat steps 3, 4 to complete the multi-group data measurement;
7.
Continuously press
key twice to quit the measurement status;
8.
Press direction keys
to choose “Clear” and then press
key to clear all marks and data;

Press
key to unfreeze, clear all marks and data and quit the measurement status.
7.3 Slope/Heart rate/Cycle Measurement
The method to measure slope/hear rate/cycle is identical with distance measurement.
Note: In B/M mode, if both starting point and end point of the measurement mark fall into the
B-mode area, the value of the “+:” refers to distance; if starting point and end point of the
measurement mark fall into the M-mode area, the value of the “+:” refers to depth; if the
starting point and end point are in separate areas, the “+:”will display “----”sign or invalid
value.
＋
: denotes depth measured in mm (millimeter)
EF: denotes slope coefficient measured in mm/s (millimeter per second)
HR: denotes heart rate measured in times/minute (times per minute)
T: denotes cycle measured in ms (millisecond)
Attention:
The accuracy of software measurement: distance measurement ≤ 1mm;
area measurement ≤ 1mm
2
; volume measurement ≤ 1cm
3
; heart rate measurement ≤
1bpm; time measurement ≤ 1ms. Due to differences in images obtained by each user in
different times, the actual object for the accuracy of the measurement may be greater
than the above-mentioned values.
