iii. Filling the probe pen with testing liquid
For safety and transport reasons, the probe pen does not
come pre-filled with testing liquid. Once you connect the
probe pen to the tester unit and power up the device, you
will need to fill the probe pen with the testing liquid, when
using the tester for the first time.
This process is similar to refilling your probe pen later when
testing liquid is low.
To prepare, ensure you open 1 sealed vial of the provided
testing liquid and have the provided petri dish prepared.
You should always only use the Presidium Gold Karat
testing liquid provided to you in sealed vials to fill or refill
your tester.
On the main menu, go to the fourth option
<<Refill>>
and
press “Enter”.
