【Thermal Screening】 The metal probe and level meter check a stone's thermal response; level indicators and audible cues support screening of loose stones and mounted jewelry.
【6-Level Calibration】 Adjust levels 1-6 for stone size and ambient temperature: use a higher level for smaller stones or cooler rooms and a lower level for larger stones or warmer rooms.
【Correct Test Setup】 Power on, wait about 30 seconds for the Ready Lamp, clean the stone, then touch its surface vertically and gently; heavy pressure may damage the probe.
【Conductive Panel and Alert】 Use bare hands with normal moisture and keep fingers on the back panel. A continuous buzz signals metal contact so you can reposition the probe on the stone.
【Complete 9V Kit】 Includes the 106 g tester, loose-stone platform, vinyl storage case, and one 006P 9V battery. Remove the battery before long-term storage.
