4-14 Testing the Instrument
Note: the selected value must be within ±10% of the current measured ambient
pressure, otherwise an error message will occur at restarting the Monitor.
6WHS Confirm the barometric pressure setting.
6WHS Check that the ambient pressure displayed in the status line at the bottom of the
screen is the same as the value which you selected from the list in step 5.

The leakage check consists of two parts:
• Check of tubing between the pump outlet and the M3015A outlet.
• Check of tubing between the pump inlet and FilterLine inlet.

.
6WHS Connect a FilterLine to the sidestream CO
input to start the pump running.
6WHS Check the ambient and cell pressure shown in the status line on the screen. The cell
pressure should be approximately 20 mmHg lower than ambient pressure.
6WHS Connect the flowmeter outlet to the FilterLine inlet using a flexible connecting
tube.
6WHS Block the M3015A outlet using your fingertip and observe the flowmeter display.
The value on the flowmeter (x2) should decrease to between 0 and 4 ml/min,
accompanied by an audible increase in pump noise. If the value is within the toler-
ance limits, continue with Part 2 of the leakage check.
6WHS If the value is outside the tolerance limits, there is a leakage between the pump out-
let and the M3015A gas outlet.
6WHS Open the M3015A and check the tubing connections at the pump outlet and the
M3015A gas outlet. If the connections are good, then there is a leakage in the tub-
ing and the M3015A must be exchanged.

6WHS Disconnect the flowmeter from the Part 1 setup and connect the flowmeter inlet to
the M3015A gas outlet.
6WHS Leave the Filterline connected to the M3015A inlet.
6WHS Block the inlet of the FilterLine using your fingertip and observe the flowmeter dis-
play. The value on the flowmeter (x3) should decrease to between 0 and 4 ml/min,
