Page 9: Operating Instructions
OPERATING INSTRUCTIONS This meter comes with an exclusive patented technology featuring bright LEDs indicating the correct input jack to plug-in the positive (red) test lead for the selected function. The LED turns off after the test lead is completely plugged in the correct jack. If the test lead is plugged in the wrong jack, the LED will start flashing and the buzzer will start beeping. -
