Sensor Information
26
g)
DC test: This value varies with the input DC input voltages. Connect the infusion pump to the DC
power supply and check whether the test value falls within the range of 14-16V. Then, disconnect the
pump from the DC power supply and check whether the test value is about 6V. If the voltage is
incorrect, the power module may be faulty.
h)
Battery test: Install the battery in the infusion pump and check whether the test value is stable and falls
within the range of 9-13V. If the test value keeps changing, the battery may be damaged or the main
board is faulty.
i)
VDD test: The normal value is 3.3±0.2V. If the test value is abnormal, the main board may be faulty.
j)
VAA test: The normal value is 24±2V. If the test value is abnormal, the main board may be faulty.
k)
VCC test: The normal value is 3.3±0.2V. If the test value is abnormal, the main board may be faulty.
