To progress onto the next test, ensure first that any 

excess liquids left on the testing platform or on the probe 

pen is wiped away. Then, either press the dispenser 

button or press “Enter” and the screen will go into Ready 

mode, with the last test result still displayed at the bottom 

right corner (Fig 3.1d). 

Hold the probe pen against the next test item and press 

the dispenser button to start the next test. 

Refer to Section 6 – Part A and Part B for possible errors 

that may occur during testing.  

i. Using the Testing Clip

The testing clip helps to secure the sample of gold 

or gold jewelry to the conductive plate of the testing 

platform. It is also designed to accommodate different 

sizes of rings.

Place the gold item on the conductive plate and use the 

clip to secure it to the testing platform (Fig 3.2).
