Calibrations Procedures (part number 508137).
• Test Kit (part number 150034), which contains two pressure gauges with
fittings and hoses for measuring loading pressure and deaeration pressure.
• Dialysate meter to measure dialysate pressure, temperature and conductivity at
the ends of the dialysate lines. The meter must be capable of making pressure
measurements from -250mmHg to +400mmHg with an accuracy of at least
±3mmHg. The temperature function of this meter must be accurate within
0.2°C from 20°C to 45°C and must be capable of measuring dialysate
temperatures up to 85°C with an accuracy of at least ±4.0°C. The conductivity
function of this meter must be accurate to within 0.1mS over a range of 12mS to
17mS at a temperature of 25°C.
• Stopwatch with a resolution to 0.01 second and an accuracy of 0.01% or better.
• Buret, 25ml capacity with 0.1ml graduations (part number 290104).
• Graduated cylinder: 1000ml capacity with a tolerance of 10.0ml at 1000ml or
better.
• Syringe, 60cc capacity. Tolerance is not important; the syringe is not used for
volume measurements.
• Tubing, 24” long (part number 545325-10). Use on the tip of the Buret.
• Resistor Plug Set for OLC Testing (part number 190168).
The following equipment is also required to test the blood pressure module:
• Dummy Cuff (part number 370090). The Dummy Cuff contains two air
chambers with calibrated volumes.
• Mercury manometer or equivalent pressure meter accurate to within 1mmHg at
pressures up to 330mmHg.
