Warning
To avoid harms to you or damages to the Meter from eletric shock, do not
attempt to measure voltages higher than 750V AC or 1000V DC, although
readings may be obtained.
To measure DC/AC voltages, connect the Meter as follows:
1. Insert the red test lead into the V Hz terminal and black test lead into the
COM terminal.
2. Set the rotary switch to V . DC mesaurement mode is a default. Press
SELECT to switch to AC measurement mode. Press RANGE to enter manual
ranging.
3. Press Hz% button to measure frequency or duty cycle, but the frequency or
duty cycle readings obtained from this range is only for reference.
4. Connect the test leads across with the object being measured. The measured
value shows on the display.
Note:
● AC Millivolt is a manual ranging measurement mode.
● In each range, the Meter has an input impedance of 10MΩ. This loading
effect can cause measurement errors in high impedance circuits. If the
