VI. Operation Instructions
1. Measurement of AC/ DC Voltage
 Select AC or DC voltage function.
 Insert the red probe into the red hole (positive pole) and the black probe into the black hole
(COM terminal).
 Get the red and black probes to contact tested parts, such as power outlets, etc. (Figure 3).
 Read the measured value from the LCD screen.
When it is used to measure voltage, the maximum input voltage value is 600V (AC/ DC) and
the measured value cannot exceed this limit, or else it is easy to cause the risk of electric shock
and may do damage to the instrument.
