Electrical Specification:                                                                                  

Supply Voltage                        90 - 260 VAC. Supply Frequency                                                    50 - 60 Hz. Supply Power    < 30 VA.

Fuse                                           20 mm 250 V, 1 A (T) (slow blow).

Earth Leakage Current          < 1.0 mA in single fault condition.

Flow Rate Measurement                                                                                  

Technique:     Flow is calculated by measuring a volume over time.

Range:            0.5 - 1000 ml/hr.

Accuracy:      1% of reading ± 1 LSD for flows of 16 - 200 ml/hr for volumes over 20 ml.

Otherwise, 2% of reading ± 1LSD after delivery of 10 ml under laboratory conditions.

Volume Measurement                                                                                      

Technique:     Volume is measured directly by the transducer in minimum sample sizes of

60 micro-liters.

Range:            0.06 - 9999 ml.

Accuracy:      1% of reading ± 1 LSD for flows of 16 - 200 ml/hr for volumes over 20 ml.

Otherwise, 2% of reading ± 1LSD after delivery of 10 ml under laboratory conditions.

PCA Bolus Measurement                                                                                  

Technique:     Volume is measured directly by the transducer in minimum bolus volumes of 0.5 ml. The measurement is made with a continuous rate between 0.0 and

30 ml/hr. The bolus flow rate should be at least four times the basal flow

rate for reliable detection of boluses.

Min Bolus:     0.5 ml.

Accuracy:      See volume measurement.

Pressure Measurement                                                                                    

Technique:     Direct occlusion of the infusion line and measurement of pressure prior to the glass transducer.

Range:            0 to 45 PSI and equivalents in mmHg and kPa.

Accuracy:      1% of Full Scale ± 1 LSD under laboratory conditions.
