Calibration is also required after the following actions:
• Changing the sniffer line (at least 20 minutes waiting time after connecting a PLUS
sniffer line)
• Switching the sniffer probe
• Switching between the gases
• Request for calibration by the system
If you insert a COOL-Check calibration leak then this is the easiest method to calibrate
the device.
Insert the COOL-Check into the base plate of the device, see “Change calibration leak
(SMART only) [
}
74]“.
The leakage rate of the COOL-Check is temperature compensated and thus makes
the accuracy required for calibration possible. The COOL-Check calibration leak
contains R134a.
The most accurate calibration is achieved with the external calibration leak. The
calibration leaks apply to one gas each and are temperature resistant.
When using a sniffer line for R744 (CO
2
) or a sniffer line for R600a/R290 then
calibration can only take place with one external calibration leak.
The gas that leaks from the calibration leak is carried away by strong air currents.
Keep this in mind when, for example, a fan blower is standing in your surroundings.
Strong air currents provide false results when calibrating.
If you have assembled an extension hose for the sniffer tip then before calibrating with
the internal COOL-Check insert a centering ring to make the calibration opening on
the device smaller, see “Using an extension hose for a sniffer tip [
}
31]“. The centering
ring is contained in the shipment of a set with extension hoses for the sniffer tip.
Calibrate the device at least five minutes after switching it on. After the warm-up
phase it is ensured that the device calibrates optimally.
6.3.6.2 Calibration with an internal COOL-Check
A COOL-Check has a life of about 2 years. It is announced on the basic unit that the
life of the COOL-Check is running short 3 months before this time has elapsed. For
this reason never keep a supply of COOL-Checks. Store the COOL-Check in a cool,
dry place. See also "Change calibration leak (SMART only) [
}
74]".
