measurement, hold on to the " " key for more than
2 seconds to turn on the backlight source.
2) Hold on to the " " key again for more than
2 seconds to turn off the backlight source.
3) After the backlight source is turned on, if the " "
key is not held down for more than 2 seconds, the
backlight source will shut down automatically 15
seconds later.
4.6 Use Of The Test Key
1) Press "TEST" to start detection when the meter is at
the Phone (phone line mode detection), Tone
(judgment and tracking of cable line), Net Cable
(network cable integrity detection) range.
2) After the detection, the detection result indicator will

be replaced.
2) The “ ” symbol beside the input line indicates that
the input voltage or current should not exceed the
indicated value. This is intended to protect the
internal circuit from damage.
3) Set the range selector to the desired measurement
function and range. In the manual range mode, if the
scale of the measured value is unknown beforehand,
the highest range should be set.

because the meter is highly sensitive. When the test
probes contact the circuit, the true reading will be
displayed.
2) In the manual range mode, if the LCD displays “O L”
or “-O L” only, it means the measurement has exceeded
the range and a higher range should be selected.
