2. Operation instruction and use scope of the tester
Voltage and continuity tester, has such functions as AC/DC (including three-phase alternating current)
voltage measurement, three-phase AC phase indication, frequency measurement, RCD test, continuity
test, single test pen testing, the simple test in case of no battery power supply, self-inspection, silent mode
choice, overvoltage indication and low-voltage battery indication. ln addition, the flashlight attached to the
test pen provides convenient application in a dark environment.
To protect tester and, more particularly, the tester user, the tester is equipped with protecting jacket. The
tester should be put on protective jacket after use and, preferably, placed inside tool kit so as to protect it
against any damage. Never place the tester into your pocket.
The tester is applicable to various occasions such as the household, factory, electric power department, etc.
It has the following characteristics:
1. To protect physical injury, it is designed with protecting jacket;
2. LCD voltage and frequency display;
3. AC/DC measured up to 690V;
4. To judge the zero or live wire by single test pen measurement;
5. Continuity measurement;
6. lndicate the phase relationships among three-phase AC;
7. Both the buzzing and silent mode is optional;
8. Illumination function;
9. Self-inspection function;
10. Low-battery voltage indication and measured voltage over range indication;
11. RCD test;
12. Automatic standby.

3. Safety precautions

• To prevent physical injury, electric shock or fire, pay special attention to following items:
• Before using a voltage detector with audible indicator at locations with a high background noise level, it
has to be determined whether the audible signal is perceptible.
• the voltage detectors are designed to be used by skilled persons and in accordance with sale methods
of work.
• The different indicating signals of the voltage detector (including the ELV limit indication) are not to be
used for measuring purposes.
• Be sure both the test pen and test instrument is intact before test;
• When using the test pen without caver caps, measurement must not be performed above the measuring
category GAT Il. When measurement in the measuring category GAT Il l 690 Vor GAT IV 600V. the cover
caps must be pushed onto the test pen to avoid accidental short circuits during measurement.
• Be sure keep your hand only in contact with the handle while using the equipment;
