4.2.1 Voltages < 24 V
For voltages of less than 24 V the device must be
switched on or over by actuating the push-button
.
4.2.2 Voltages 24 ... 1000 V AC / 1500 V DC
(Nominal voltage range in accordance with IEC
61243-3). The device automatically indicates the
type of voltage (AC / DC), voltage in „V" on the
display.
4.2.3 Voltages 1000 V AC ... 1200 V AC
(exceeds the limit values in accordance with
IEC 61243-3). With the METRAVOLT 12D+L you can
perform secure tests above the nominal voltage
range up to 1200 V AC. The measurment value is
indicated by flashing in the display.
4.2.4 Voltages > 1200 V AC / 1500 V DC
"OL" in the display and an acoustic alarm warn
against voltages exceeding 1200 V AC / 1500 V DC.
In this case, the test procedure must be stopped
immediately!
4.3 Testing phase and phase sequence
The METRAVOLT 12D+L is equipped with 2 triangu-
lar LEDs for the indication of phase sequence tests.
Attention!
These tests can be performed at a nominal voltage of
at least 165 V (50 Hz) against earth.
When performing these tests, the device must be
hold closely at the handgear of the display part
(see picture below).
Note: You may wear insulating gloves when perfor-
ming the tests.
Tests can be impaired by unfavourable locations,
for example on wooden ladders or insulating floor
coverings, as well as in improperly earthed AC
voltage systems.
4.3.1 Phase test
Determination of the outer conductor occurs by
applying the test electrode +L1 to the conductor.
When "POL" appears on the display, the conductor
is live.
