Continuity Test; Cleaning And Maintenance - VOLTCRAFT VC-55 lcd Bedienungsanleitung

The two probe tips L1 und L2 can be connected to one another, laterally via the
fastening clamp on the handle grip barrier of probe tip L1 (5).
The distance between the two probes is 19 mm, which complies with the standard-
ized contact gap for EU and safety socket outlets.
In addition, establishing contact inside the outlets is made even easier when the
included 4 mm adapter screws are used. That way, the voltage tester can be guided
by using one hand only.
Make sure that your hand remains within the grip area (16) of probe tip
L2 and that you don't cover the display.
b) Rotating field indicator
VC-55 shows the rotating field direction of properly grounded three-phase systems (with batter-
ies only). The voltage tester detects the order of increasing phases to ground potential
Hold the voltage tester by the handles (1) and (16) provided. Never touch the device beyond
the handle ends.
Connect the two probes to the measuring points that you want to measure.
The probe L1 (4) corresponds to the outer cable (phase) L1.
The probe L1 (6) corresponds to the outer cable (phase) L2.
The available voltage range and the phase sequence is represented on the display.
The illuminated indicators (12) show the applicable rotating field direction (L = left turning / R
= right turning).
Example 1:
Probe tip L1 to outer cable L1,
Probe tip L2 to outer cable L2,
The correct field rotation "R" is displayed
Example 3:
Probe tip L1 to outer cable L2,
Probe tip L2 to outer cable L1,
Opposite phase sequence "L" is displayed
c) Continuity test
When batteries are inserted, the VC-55 can be used as a continuity tester.
Hold the voltage tester by the handles (1) and (16) provided. Never touch the device beyond
the handle ends.
Check function before your start metering.
Connect both probe tips to one another. A signal sounds and the display is illuminated (11).
If this is not the case, replace the batteries as described under "Inserting/Replacing the Bat-
teries".
The continuity tester indicates a resistance of about 0 - 500 kΩ (+50%) as continuity.
d) Single-pole phase test
When batteries are inserted, the VC-55 can be used as a single-pole phase tester.
Hold the voltage tester by the handles (1) and (16) provided. Never touch the device beyond
the handle ends.
This single-pole phase test serves as a quick test only, and prior to any work con-
ducted on this line the absence of voltage must be rechecked using the double-pole
measuring method. Observe the regulations regarding work with electrical systems.
Contact probe tip L2 with the measuring point to be tested. Probe L1 has no contact.
If an alternating voltage >100 V is present, the indicator (10) lights up and a signal sounds.
The single-pole phase display may be adversely affected by unfavourable ambient
conditions (electrostatic fields, good insulation etc.). However, perform an additional
double-pole voltage test to determine that voltage is absent.

Cleaning and Maintenance

Besides occasional cleaning and battery replacement, the voltage tester is maintenance-free.
The voltage tester must be disconnected from all devices under test before cleaning.
After cleaning, allow the product to dry completely before using it again.
Never try to open the housing, apart from the battery compartment.
Check the technical safety of the voltage tester regularly. It is understood that safe operation
is no longer possible:
- if the device or he connecting cable is visibly damaged
- after prolonged storage under unfavourable conditions
- after extraordinary transport stress
The outside of the device should be cleaned with a soft, damp cloth or brush only. Do not use
abrasive or chemical cleaning agents which could damage the housing or impair operation.
Example 2:
probe tip L1 to outer cable L2,
probe tip L2 to outer cable L3,
The correct field rotation "R" is displayed
Disposal
a) General
Electronic products are recyclables and do not belong in the household waste.
When the device has reached the end of its service life, please dispose of it, accord-
ing to the current statutory requirements, at your local collecting site. It is prohibited
to dispose of the device with domestic waste.
b) Batteries
You as the ultimate consumer are legally obliged (Regulation on Spent Batteries) to return all
dead batteries; disposal in the household waste is prohibited!
Batteries containing hazardous substance are marked by the symbols alongside
which indicates the prohibition of disposal with domestic waste. The symbols of
the relevant heavy metals are: Cd = Cadmium, Hg = Mercury, Pb = Lead. You can
hand in your used batteries at the collection points of your community at no cost or
everywhere where batteries/accumulators are sold.
Thus you fulfil your statutory obligations and contribute to the protection of the environment!
