Ac Voltage Measurement - TESTBOY TB-3000 Bedienungsanleitung

Operation

AC voltage measurement

Set the selector switch to measurement range V~.
Insert the black test lead into the 'COM' socket and the red test lead into the
right-hand socket. Using the test probes, touch the test points of the test object.
The multimeter automatically searches for the most suitable measurement
range. Read measurement value on the display.

Max. input voltage 600 V AC RMS, frequency range: 40-400 Hz.
The red test line can be used for checking single pole phases by pressing the
"M" button. The display flashes and a signal sounds. Before measurement, it is
imperative that all other test lines are removed. This measurement is not
suitable for detecting hazardous mains voltage. Thus, also if the display does
not flash during the check and no signal is emitted, a hazardous high voltage
(>33 V AC or 70 V DC) can nevertheless be present.

Attention!
Before touching current-carrying parts, using direct, two-pole
contact measurement of the AC current range, check that no
hazardous voltage is applied.
