VIII. Operation Instructions
1. Measuring of AC Voltage/Frequency/DC Voltage
• Select AC voltage/frequency or DC voltage tap position.
• Insert red probe into red jack (positive end), and insert
black probe into blackjack (COM end).
• Touch the measured part with red and black probes,
such as power socket (Figure II).
• Read the measured value from LCD screen.
When measuring voltage or frequency, the maximum input voltage is 600V (AC/DC), and this is not
allowed to be exceeded; otherwise, it is possible to cause
electric shock and damage the instrument.
