Description Of Symbols; Continuity Test - VOLTCRAFT VC-63 SE Bedienungsanleitung

DESCRIPTION OF SYMBOLS

Alternating Current (AC)
V/AC: Alternating voltage
V AC DC
V/DC: Direct current
12/24/36/50/120/230/400/690 Display of rated voltage range in volt (V)
Direct current positive potential DC
Direct current negative potential DC
k Ω Electrical resistance in kilo-ohm
Hz Electrical frequency (Hertz)
single-pole phase display 100 - 690 V as well as warning for
hazardous voltage (>50 V/AC, >120 V/DC)
Operation also possible with flat batteries or without batteries
Continuity test symbol
Battery symbol for data of used battery
Conformity symbol, CE-approved
Apparatus and equipment for live works.
Personal protection equipment required
Protection class 2 (double or reinforced insulation/protective
insulation)
INSERTING / REPLACING BATTERIES
Disconnect the voltage tester from the respective object under testing.
Hold both measuring probes together. The batteries must be replaced if no beep is heard or a flat
battery is indicated on the display. Install the two protective plastic sleeves/measuring probe covers
for your own safety. For this purpose, loosen the screw (15) using a small Phillips head screwdriver.
Now, carefully pull the battery compartment (14) downwards along the cable. Remove the empty
batteries from the measuring instrument, where applicable, and insert new batteries of the same
type (see Technical data) into the battery compartment observing the correct polarity. The use of
rechargeable batteries is not permitted. We recommend to use alkaline batteries. They guarantee
a long service life. Slide the battery compartment back upwards until you feel it click in place and
carefully close the compartment with screw (15).

FUNCTIONALITY TEST / SELF-TEST
We recommend to test the functionality of the measuring instrument before each measurement.
Hold both measuring probes together. You will hear a beep and (7) lights up. The product is ready
for operation.
The measuring instrument switches on automatically when the respective measurement unit is
detected. After a measurement step, the measuring thermometer turns itself off to save power.
If no signal sounds, replace the batteries. If functionality is not given even after replacing the batter-
ies, the product must not be used!
Additional self test function (all LED, TORCH, BUZZER are ON for 2sec) is implemented for all
Conrad VTs. It can be started when VT is off. The user need to push Torch button and hold for 4
sec. After that all LED/symbols light, Torch light and buzzer sound is active for 2sec.
Always attach the measuring probe cover if you are no longer using the device.
VOLTAGE TEST
Connect the two measuring probes with the object to be measured.
The voltage tester automatically switches on when it detects a voltage of 12 V or higher.
When using the voltage tester in the measurement category CAT III and CAT IV, it is recom-
mended to attach the plastic protective covers provided to the measuring probe to decrease
the length of the free contact probes (2) and (3). This reduces the risk of a possible short
circuit during testing.
For ease of use, the product has a holder (4) for a second measurement line. This makes
measuring e.g., directly on the mains sockets easier.
For direct current, the polarity of the voltage displays refers to the measuring probe of the
measuring instrument (3).
When the batteries are empty, only the warning indicator (5) for "Dangerous Voltage"
will function when the test voltage reaches 50 V/AC or 120 V/DC. Do not ever touch the
measuring contacts, if this indicator is on. Change the batteries.
In the LC display (8), the measured voltage (AC/DC) and the measuring range are
indicated in the bar graph.

CONTINUITY TEST

Before a continuity check, make sure that the measurement object is de-energised.
Connect the two measuring probes with the object to be measured. A signal will
sound and the LCD will show the continuity symbol (7) and Con, if the continuity
is max. 400 kΩ +50%.
Disconnect the measuring probes from the measurement object after the
measurement.
