Chapter 3 Testing
3.1 Brief Introduction
To ensure the long-term and stable working of the monitor, maintenance
personnel need to conduct regular checks, maintenance and testing on it. This chapter
provides the basic testing methods of the monitor and recommends the applicable
testing frequency and testing tools, and the maintenance personnel are requested to
conduct maintenance and testing on the monitor according to actual demands and
choose applicable testing tools.
The testing and verification methods provided by this chapter are mainly used for
verifying whether the monitor’s performance has reached the specification
requirements. During the tests, if the test results can not reach the requirements, it
indicates the monitor or a certain function module of the monitor has failures and they
need to be repaired or replaced. If you have any query, please contact the after-sale
department of our Company.
Caution:
All the testing must be done by qualified service personnel.
When setting up and changing the contents in the two menus of
Manage】and【Maintenance】, please be cautious, otherwise it might cause data
loss.
Prior to executing tests, the service personnel are kindly requested to ensure
the applicability of the testing tools and cables and service personnel shall be
familiar with the use of these testing tools.

Config
3.2 General Testing
3.2.1 Visual Check
Visual check is mainly for overall appearance check on the monitor, and if the
monitor has no obvious physical damage, visual check is qualified.
Check items are as follows:
1. Whether the host monitors’ enclosure, display screen or keys have any physical
damage.
2. Whether accessories have any physical damage, any wear or tear, whether the
Page 20
Service Manual of S10&S12 Patient Monitor
19
connector pins have any loosening or distortion.
3. Whether the peripheral interface of the monitor has any loosening or pin distortion.
4. Whether the safety labels or name plates are legible.
3.2.2 Startup Testing
Startup test is used to verify whether the monitor can be normally started to work,
and if the monitor can accomplish startup according to the following procedures, the
startup test is qualified. The procedures are as below:
1. Connect the monitor to the AC power. AC power indicator lights up.
2. Press the power switch, the technical alarm indicator lights up in blue, and the
physiological alarm indicator lights up in yellow and red in turn and then goes off, the
screen displays the startup image.
3. After the startup image disappears, the system produces a “dang” sound and goes
into the main screen; at the same time, the technical alarm light goes off.
4. The monitor goes into the system’s main screen and normal startup is completed.
Warning:
If the monitor is mechanically damaged, or if it is not working properly, do not
use it for any monitoring procedure on a patient. Contact your service personnel.
Caution:
The monitor does not have mains switch. The monitor is switched completely
only by unplugging the power cable from the AC power source. In order to
unplugging and plugging it, the socket on the wall must approximate to
monitor.
For measurements in or near the heart we recommend connecting the
monitor to the equipotential grounding system. Use the green/yellow
equipotential grounding cable and connect it to the terminal labeled with the
symbol .
