7.4 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

; volume measurement ≤ 1cm

; 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.
