instructed to thoroughly dry their hands before testing.
Wet hands may cause inaccurate test results and
damage to the tester.

power adapter to the Combo Tester X3+.
2. Route all cables through the U-shaped opening
located at the bottom of the Combo Tester X3+ and
secure them to the cable tie mount with the included

outlet, and power the Combo Tester X3+ by sliding
