4.5.3 Calibrated leak (COOL-Check)
The calibrated leak is located in the bottom of the main unit. It consists of a gas
canister with a printed circuit board attached to the bottom.
When the calibrated leak is nearly empty, the message "Leak nearly empty. Please
replace!” will be displayed.
The user will have to replace the calibrated leak within two to three months before
the calibrated leak will be completely empty.
How to replace the COOL-Check is described in Chapter 6.2.5.
Notice Replacement leaks should not be purchased in advance of their need as
they have a limited lifetime.

To convert the HLD5000 to a different probe shut down the HLD5000, unplug the
current sniffer line and connect a different sniffer line with a different probe. The
