"HOLD" button.
After "Hold" button is pressed, the present reading will be held in the display.
2.
"LIGHT" button.
To enable spotlight function, press "Light" button.
To disable, press the "Light" button again.
3.
"SELECT" button.
When meter is in the Vdc range press the "Select" button to change to
the Vac range, press "Select" again and the meter will return to the Vdc range..
When the meter is in the resistance range press the "Select" button to change to
to diode range. Press "Select" again, for continuity range. Press "Select"
again for capacitance range.
When the meter is in frequency range, press the "Select" button for
duty cycle.
4.
"POWER" button.
The "Power" button is used for switching the meter on.
Press "Power" again to turn the meter off.
5.

If < 50Ω, the buzzer will sound
Note: When the resistance is between 50Ω and
120Ω, the buzzer may or may not sound. When
the resistance is more than 120Ω, the buzzer
will not sound.
