UNI-T UT212 Operating Manual page 14

Full auto measurement mode
To measure DC and AC voltage, connect the Meter as follows:
1. Insert the red test lead into the V terminal and the black test lead into the COM
terminal
2. Connect the test leads across with the object being measured. When the AC
voltage is higher than AC1.5V or DC voltage is higher than ±1V, the Meter will
automatically enter the voltages measurement mode.
The measured value shows on the display.
3. When the input voltage is less than 5V, the input impedance is around 10M .
When the voltage is higher than 5V, the input impedance will instantly transit from
1k to 10M .
Semi auto measurement mode
Press SAVE button to turn the Meter on, the Meter will then enter into voltage
measurement mode, the input impedance is 10M
default as DC voltage measurement mode. The Meter will auto identify the voltage
type and switch to the appropriate measurement mode.
