3. DIAGNOSTIC CHECK
Service Manual BSM-4100 3.37
5. Deflation Speed
NOTE
Skip this deflation speed check because it is covered in the “6. Step
Deflation” check.
This is used to check the deflation speed through the two solenoid valves (V1 and
V2) at different stages of pressure drop. An “OK” message is displayed if it takes
1.4 to 3.0 seconds for V1 and 2.5 to 4.3 seconds for V2. If not, an “ERROR”
message is displayed.
Checking the Deflation Speed
1. Connect the 700 ml dummy cuff to the instrument with the 3.5 m air hose as
shown below.
2. Touch the “SELECT” key to select item number 5.
3. Touch the “START” key to start the check.
If an “ERROR” message appears, replace the NIBP Safety board or pneumatic
circuit with a new one.
