Connect the black test lead to the ground terminal of the circuit to be measured, the test probe
to the desired test point of the circuit.
•
If the level of the test point is more than or equal to 2.3±0.2V, the LCD will show
and the
voltage value, meanwhile the meter will sound discontinuously.
•
If the level of the test point is less than or equal to 0.8±0.2V, the LCD will show
and the
voltage value, meanwhile the meter will sound continuously.
•
If the probes are open, the LCD will show a TTL logic level’s approximate midvalue: 1.0~1.4V.
Auto Power off
If the meter is not operated for about 15 minutes, it will turn off automatically and stay in Sleep
mode.
To arouse the meter from Sleep, turn the function switch or press the
button.
BATTERY REPLACEMENT
When the symbol

battery of the same type. Reinstall the battery cover and reinstall the screw.
Note:
Before replacing battery, set the function switch to OFF position.
FUSE REPLACEMENT
Fuse rarely needs replacement and is blown almost always as a result of operator’s error. The meter
uses a fuse with specified ratings: F 250mA L 250V
To replace the meter’s fuse:
•
Set the function switch to
OFF
position.
•
Remove the battery door (“c”)
•
Remove the “a” part by turning it.
•
Remove the back cover’s screws, then remove the back cover (“b”).
•
Remove the fuse by gently prying one end loose, then slide the fuse out of its bracket.
•
Install a new fuse of the specified ratings.
•
Reinstall the back cover, battery door the “a” part and all the screws.
