5. PURGING your Gold Karat Tester
As the probe pen consists of a mechanical motor that
helps it to take in testing liquid during a refill and dispense
testing liquid during a test, it is likely that sometimes air
bubbles can be trapped in the probe pen, especially when
refilling.
The
<<Purge>>
option, fifth in the main menu, will help
you to perform purging to remove any air bubbles in the
probe pen, so that the testing liquid can be dispensed
optimally and consistently.

You are advised to perform purging on your device in
these situations:
a. After each refill
b. If you see visible air bubbles trapped inside
(through the window on the probe pen)
c. Inactivity of the device for more than 24 hours
d. During testing and no liquid is dispensed
To begin the Purge process, press “Enter” on the
<<Purge>> option and follow the instructions as they
appear on screen.
There are a total of 6 steps in the <<Purge>> process.
Be careful and twist gently when removing and replacing
the probe tip. Do not point the tester at another person
when purging the device.
For possible errors or problems during Purge, refer to
Section 6 – Part E.
