GB | Voltage Tester
VT-211 is a tester designed for two-pole measurement of DC and AC voltage in a range of 6 to 400
V and frequency of 0–60 Hz, and for determining the polarity of DC voltage. The tester complies
with standard EN 61243-3:2014 in the 6–400 V / CAT III 400 V range. The tester can be used for
making measurements on electrical wiring and devices falling within overvoltage category CAT
III 400 V. Overvoltage category CAT III also includes category CAT II for electrical devices and
equipment with special requirements for safety and usability. These are, for instance, domestic
wiring, protective installations, power sockets, switches, circuit breakers, etc.

Description of Tester
1 – Tester barrier
2 – Measuring tip of the tester
3 – Removable cover of the tester tip
4 – Polarity LEDs
5 – LEDs indicating AC voltage
6 – Mobile measuring tip
7 – Removable cover of the mobile
tester tip
8 – Barrier of the mobile section of
the tester
Use
The tester indicates voltage by lighting up LEDs up to the measured voltage. First, touch the
live portion (L) of the circuit with the tip located on the fixed part of the tester. Then touch the
neutral portion (N) using the mobile tip. If the circuit is powered and you are measuring correctly,
LEDs indicating the corresponding voltage will light up. When measuring DC voltage, only the
corresponding polarity (+/-) will be indicated. The fixed tip is the positive pole.
Maintenance
The tester is maintenance-free.
Cleaning
The body of the tester may occasionally be cleaned with a soft cloth slightly moistened in a mild
solution of a common household cleaner. Do not use aggressive solvents. Make sure water does
not enter the interior of the tester. Could cause damage or short circuit.
WARNING
• Do not use the device if the lead or cover are damaged.
