Measuring Voltage:

1. The red clip is to be connected with the positive (+) polarity, and the black clip connected with the negative (-) polarity. The LED will display �00.0� when nothing is connected with the testing probe

2. When the test probe is connected to a positive voltage, the LED display will show a reading only if the voltage is greater than 0.3VDC. If the voltage is greater than 62VDC, the LED display will read �Err�

 

Continuity Testing:

1. The red clip is to be connected with the positive (+) polarity, and the black clip is connected with the negative (-) polarity. The LED will display �00.0� when nothing is connected with the testing probe
