calibrated leak on.
VS Series Component Leak Detector
If the system was recently calibrated before shut down, it can
NOTE
be used for qualitative testing. Read the standard leak to verify
accuracy. For more accurate quantitative leak values, perform a
calibration 30 minutes after start-up.
To accurately read in the most sensitive decades of each
working range, perform a tune, calibration and offset, and
internal or external calibration after a 20-30 minute warm up.
The VS C15 Base unit is always in Test/Measurement mode.
