5.3. Illumination Function
Press and hold down the ” ” button to turn on the illumination LED. To turn off the illumination LED,
just release this button.
6. Battery replacement
After you turn on the unit, the detection indicator LED will flash red periodically if the batteries are high
enough. If the detection indicator LED does not flash periodically, the batteries are low and must be
replaced immediately.
Before replacing batteries, turn off the unit by turning the knob backwards until a click is heard. Then re-
move the battery cover and replace the old batteries with two new batteries of the same type (1.5V battery,
AAA or equivalent), make sure that the polarity connections are correct. Reinstall the battery cover.
7. Note
1. Don’t use the unit to detect an ac voltage below 5V ac or above 1000V ac. Do not use the unit for any dc
voltage detection.
2. If there are several lines, such as 2-phase wires or 3-phase wires, separate them far enough apart from
each other and perform voltage detection on each line.
3. Because the unit’s detection limit, sensivity setting and the detection distance can affect detection, the
object under test may be live even if the built-in buzzer does not beep and the detection indicator LED does
not flash. To avoid electric shock and personal injury, don’t touch any naked conductor with hand or skin.
4. Due to the interference caused by the electric field in environment, the unit may give alarm even if the
object under test does not contain ac voltage. To avoid false alarm, don’t use the unit in an intense electric
field environment.
5. Do not use the unit if it is damaged or operates abnormally.
6. Do not use the unit for detection on any shielded conductor.
7. If a power socket’s Live terminal and Neutral terminal are too close to each other, it will be impossible
for the unit to discriminate between them.
8. Electrical symbols
- Alternating Current
- Caution, risk of electric shock
- The equipment is protected throughout by double insulation or reinforced insulation.
