The following step-by-step procedure must be followed to properly perform gold tests: 

Low Karatage Testing (6-18 karat) 

 

Remove stationary/rotary cap from sensor nozzle by turning the lower LIGHT-
COLORED barrel counter clockwise. 

 

Remove the polyethylene cap on the gel cartridge and fully insert the rectangular feed-screw end into the appropriate slot of 
the rotary cap. Reassemble the cap assembled and cartridge into the sensor body. (See diagram 1) 
 

 

Turn the light-colored barrel clockwise until fully seated. 

 

Turn the dark-colored barrel counter clockwise until the first drop of gel appears at the sensor nozzle. 

 

Connect the black wire to the sensor plug outlet, the black and red wire connector to the display unit, and red wire to the 
testing plate. 

 

Turn the unit "ON". It will automatically be set to low karatage. If Hi Karatage Testing is desired, press the "HI/LOW KARAT" 
switch to illuminate the "HI KARAT ON" light and refer to the Hi Karatage Testing section. 

 

Select and clean with eraser a testing point on the object; obtain one drop of gel by turning the sensor rotary cap (dark 
colored barrel) counter-clockwise until gel is dispersed from sensor end. Firmly press the sensor nozzle to the pre-selected 
and cleaned testing point and press the "TEST" button. NOTE: use only a small amount of gel to test. (See diagram 2). It is 
only necessary to wet gold surface at sensor tip. 
After the test, there should be a small round wet spot on the tested sample.
