VERIFICATION OF BLOOD-PRESSURE SPECS
SETUP
1. Connect the MPS450 BP calibration cable to BP1.
2. Connect the +power supply to the brown wire, and the –power supply to the yellow wire.
3. Connect the +DMM to the brown wire, and connect the –DMM to the yellow wire.
4. Change the DMM setting to read 30 V DC with Null off.
5. Adjust the power supply (NOT the MPS450) for 10 ± 0.01 V.
6. Move the +DMM connection to the orange wire, and the –DMM connection to the blue wire.
7. Maintain the DMM and power-supply connections for all blood-pressure measurements.
NOTE: For some blood-pressure-specification tests, all that is required is to zero
the DMM, while other tests show a DMM reading and a tolerance.
