Inserting/replacing the batteries

The voltage tester needs battery power for its basic function as a two-pole voltage tester with
a voltage range indicator and its additional functions such as metering point light, continuity
test, phase sequence indication or "single pole" phase tester. Two micro batteries (type AAA/
LR03, included in delivery) are required for this purpose. The use of rechargeable batteries is
not permitted.
To insert/replace the battery, proceed as follows:
• Remove the voltage tester from all metering points and attach the protective cover to the
probes.
• Open the battery compartment (17) by releasing the lock with a flat ob-
ject (e.g. wide slot screwdriver) in a 90° counter-clockwise rotation. At
its side, a small groove is exposed that allows you remove the battery
compartment cover from the device.
• Insert two new micro-batteries (LR03/AAA) into the battery compart-
ment. Pay attention to the polarity indicated on the battery compartment
cover. If possible, use alkaline batteries. They guarantee a longer ser-
vice life.
• Close and lock the battery compartment in reverse order. Make sure that the sealing ring on
the battery compartment does not get pinched or damaged. There is only one position for
the battery compartment cover to match the device. The groove must be located on the right.
Battery replacement is necessary when the level indicator (8) is no longer illuminated during the
function test, or the battery replacement symbol appears on the LCD, or if you cannot hear the
signal sound any longer, when the contacts of the two probes (4 and 6) are in contact.
When the batteries are empty, only the warning indicator (10) for "Dangerous Volt-
age" 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.
Operation while the battery compartment is open, is not permitted.
To prevent damage to the device from leaking batteries, remove the batteries from the device
if you will not be using it for a longer period. For the same reason, we recommend that you
remove flat batteries immediately.
Compatible alkaline batteries can be obtained with the following order number:
Ord. no. 652303 (2 pcs. Please order 1x unit).
Only use alkaline batteries; they are high-performance and durable.
Mesurement Points Illumination
The VC-55 has a battery-operated measuring point illumination.
Press button (15) to turn illumination on and off. The light is on for about 130 seconds and
disappears automatically.
Performing Tests and Measurements
The two-pole voltage tester consists of the two probes (4 and 6), a connecting cable (18) and
the indicator panel.
Always hold the voltage tester in a way, that you can look down onto the indicator panel. Il-
luminated indicators may be adversely affected by strong light.
For DC measurements, the probe tip L2+ (6) is the positive pole, and the probe tip L1- (4) is
the negative pole.
The VC-55 will autonomously turn on when the test starts (entry level >10 V), and when the test
has been completed, it turns off.
Always check that the voltage tester is functioning properly prior and after employ-
ment. Measure a known voltage source (mains voltage 230 V/AC, for example)
first, and check the accuracy of the readouts. In the event of one or more indicating
ranges (8) fail, do not use the voltage tester.
If the meter does not display any function or individual indicator ranges are not
functioning, decommission the voltage tester. A defective voltage tester must not be
used.
Observe the regulations regarding work with electrical systems. Personal protective
equipment must be used when working on systems with dangerous electrical volt-
age.
The maximum permitted duty cycle (ON) is 30 seconds. After that time has passed,
an operational rest of 240 minutes at least, has to be maintained.
The following measurement functions can be conducted:
a) Two-pole voltage metering
Always hold the voltage tester by the handles designed for this purpose (1 and 16). Never
reach beyond the tactile barrier of the grip (5 and 13).
Guide the two probe tips onto the measurement points to be tested. The voltage range is shown
on the level indicator (8) and the present measuring voltage is shown on the LCD display.
The light indicators (+) and (-) show the type of voltage and the corresponding polarity. If both
indicators, LED (+) and (-) are lit at the same time, alternating current (AC) is present. Polarity
is only indicated by means of the two LEDs.
At a voltage of about 38 V/AC or 100 V/DC a signal sound is produced. The rotating field indica-
tor "L" and "R" may flash during metering. This is a technical issue and is without significance
or impact on the measuring process.
