USER MANUAL
Professional voltage detector HT20s

1. Safety precautions and procedures

Please follow the herewith indications before and during
the performance of any test with the instrument:

An improper use can damage the
instrument and/or its components or
injure the operator

Avoid using the instrument in rooms
where explosive gas, combustible gas,
steam or excessive dust are present

Do not perform any test if you notice
anomalous
breakages,
leakages of battery liquid on meter

Do not perform any test exceeding the
declared voltage conditions

Do not perform measurements under
environmental conditions
the declared limits

Do not perform any voltage detection
with operator's hand beyond the hand
safety protection

5. Operating instruction
Consider the herewith steps for a correct use:
1. Switch on the instrument by pressing
LED flashes intermittently
2. Replace internal batteries if the red LED do not turn on
and/or the buzzer do not sound
3. Position the sensor close to or in contact with the point
under test then verify that the red LED is on and buzzer
sounds continuously as evidence of voltage detection.
Do not perform test with the hand beyond the hand
safety protection and move not insulated wires
beyond the CAT IV reference mark (see part 2 of
picture)

6. Batteries replacement

Follow the herewith steps to replace internal batteries:
1. Remove the meter from any voltage source
2. Perform a small pressure on battery cover sleigh (see
part 8 of picture)
3. Shift the battery cover sleigh from the meter
4. Replace the batteries with new ones of the same type
and pay attention to keep to correct polarity indication
5. Fit the battery cover sleigh to the meter
6. Used batteries must not be disposed of as urban waste
CAUTION: this symbol indicates that the
equipment and its accessories shall be subject
to a separate collection and correct disposal
