Engineering Automatic Calibration Instructions:
The M series bladder scanner is patented in the fields of ultrasound imaging, measurement algorithm and
probe. Therefore, the M series bladder scanner has the advantage of no calibration required during the
service life in clinical application. We officially state that in the lifelong clinical application of the M series
bladder scanner and the probe, as long as they are intact, then
1. The operator does not need to calibrate the clinical measurement accuracy of the bladder scanner be-
fore first measurement of the patient's bladder volume.
2. The operator does not need to calibrate the clinical measurement accuracy of the bladder scanner dur-
ing daily application.
If any hospital or any end user regards instrument calibration as fixed operation procedure, the following
steps may be used for calibration. Please note American CIRS: 125ML Bladder Phantom is the only appli-
cable calibration phantom model designated. Since the purchased phantoms provided by the supplier are
manufactured separately, the consistency cannot be guaranteed. The material formulation of each phan-
tom is slightly different, which will affect the measurement accuracy of the phantom but will not affect the
measurement accuracy of the bladder volume of real person, therefore, we conduct automatic calibration
using American CIRS: 125ML Bladder Phantom to ensure the measurement accuracy of the phantom.
Steps of automatic calibration are as the following:
Step 1. Enter system setting interface (Figure 1). Continuously tap for six times to activate
automatic calibration which is below “Language” in the menu. Automatic calibration is not available for
normal users but only for engineering team. Ten minutes after the automatic calibration is activated, it will
be automatically shut down.
Step 2. place the probe head into the phantom holder firmly
Step 3. Tap on Calibrate in the menu to initiate automatic calibration. Calibration progress is shown as
Figure 2. The progress is displayed in %. When it reaches 100%, calibration is done. Result will also
appear. When it’s successful, result appears to be “Success” and when it’s failed, “Failure” is displayed on
the screen.
Step 4. Do not remove the probe during the calibration.
Please only conduct automatic calibration when the battery is full.
