THE GXL-24PRO DISPLAY UNIT THE MECHANICAL SENSOR The Mechanical Sensor for the GXL-24PRO Gold Tester consists of two parts: (1) the sensor body; (2) a polyethylene tube with gel. The polyethylene tube must be placed inside of the sensor's body before beginning a test. When using the Sensor be sure that: The sensor nozzle platinum contact and slots are clean. Use a cotton swab moistened with cleaner to clean the platinum contact and dry it before commencing tests and after every 6-8 repetitive tests. Dispense a drop of gel before the start of each test. It is recommended that the sensor be thoroughly cleaned with Tri SC-10 sensor cleaner when gel tube is changed or if gel is backing up around the plunger. The cleaner can be obtained from Tri Electronics or from your Tri dealer. LOADING/CHANGING THE POLYETHYLENE GEL TUBETake off the nose cone cap (See Diagram). Remove the Stationary Cap by turning the Stationary Cap (light colored barrel) counter clockwise. Please remember that the stationary Cap and the Rotary Cap are not detachable. Insert the Feed Screw Engagement into the appropriate slot of the Rotary Cap. Be sure that the Feed Screw is fully engaged. Take off Tube Cap. Insert the polyethylene gel tube until it is fully lodged in the sensor and turn the light colored barrel clockwise until fully fastened. Do not turn the dark colored top barrel clockwise or it will damage the mechanism. Turn the dark colored top barrel counter clockwise until the first drop of gel appears at the sensor nozzle (about 10-20 times to fill the cone). Diagram shows each part of the mechanical sensor. Sensor and Polyethylene Gel tube OPERATION PROCEDURE Load the polyethylene gel tube into the sensor. Connect the long black wire to the sensor's plug outlet the short black wire connector to the display unit and the red wire to the testing plate. Turn the unit "ON". The unit should display "Clean sensor tip ". Before the start of testing use the sensor nozzle cleaner or any small sharp instrument to remove dried or used gel from the dispenser opening and slots and clean the sensor tip thoroughly with a cotton swab wetted with alcohol then dry the tip thoroughly. Prepare the item for testing by thoroughly vigorously cleaning a spot on the jewelry with the eraser provided. When testing the 18-24K (750-999) gold be sure that the eraser tip does not have a black deposit. Clean the eraser on a paper. Also clean the area on the item to he clipped and place cleaned item in clip. The testing point on the object should he close to BUT NOT TOUCHING the alligator clip. Holding the sensor on the vertical position with the nozzle down twist the Rotary Cap counter clockwise a click at a time until a drop of gel appears on the tip. Wipe this first drop of gel on the towel and turn (usually one or two clicks) until afresh drop appears. Use a minimum amount of gel for testing especially for high karatage gold tests (above 18k). After dispensing a small dome of gel on the sensor tip wipe the tip on a piece of tissue paper by touching the tip to the tissue while holding the
