Voltage measurement with high internal
impedance
Always hold the voltage tester by the handles
designed for this purpose. Never touch the device
beyond the handle ends. Hold the two test tips onto
the measuring points to be tested. The voltage
tester switches on automatically with voltages
higher than 4.5V AC/DC. The voltage measured is
shown on the LCD display. If the measured voltage
falls below 4.5 V AC/DC, the voltage tester switches
off automatically.The LCD display shows the
voltage values numerically and in the form of a
bargraph. The type of voltage (alternating current =
AC or direct voltage = DC) and the polarity are also
shown on the LCD display. In the event of negative
DC voltage, the numeric voltage value is preceded
by „ - „. Positive DC voltage is shown without a
positive sign preceding the value.
Thanks to the input impedance of approx.
1MΩ, it is possible to perform voltage tests with high
