7. MEASUREMENT

(1) Power supply

Press the ON:OFF key (The display is

“display all”). After displaying the setting value

(quantity of pressure change and monitor time

for leak judgment), the display is“REDY”

(that means READY) and is in the

measurement standby mode.

(2) Starting measurement

Connect the test pipette to the tip of the

attachment securely.

Press START key. The main unit starts the

measurement by operating the pump,

evacuating the air to －20kPa. (“TEST”

display)

When - 20kPa is reached, the pump stops.

*-20kPa is approximately 0.2 atmospheres that

means that the air has been partially evacuated.

While stabilizing the inside pressure, the display

may change by 0.1 to 0.2 kPa.

The main unit measures the quantity of the

pressure changed by the monitor time set.

(“MEAS”display)

Factory setting: monitor time is 3 seconds, quantity

of pressure changed is +0.3kPa.

(3) Measurement result

When the quantity of pressure change with leakage is in less than the setting value,

the Leak Tester judges that there is no leak and displays “pa55” (normal).
