Preparation For Tests; Auto-Power-On/ Switching On; Auto-Power Off; Conducting Tests - Beta 1760PT Bedienungsanleitung

6. Preparation for tests

6.1 Auto-power-on/ switching on

• The tester switches on when it detects continuity, an AC
• It can be switched on with the torch light button.

6.2 Auto-power off

• Tester is automatically powered off after 5 sec when
• The torch light switches off after approx. 10 sec.

Safety advice
• Depending on the internal impedance of the voltage de-
• A voltage detector of relatively low internal impedance,
• When the indication "voltage present" does not appear,
• A voltage detector of relatively high internal impedance,
• When the indication "voltage present" appears on a part
• A voltage detector declaring two values of internal im-

dicate all interference voltages having an original voltage
value above the ELV level. When in contact with the parts
to be tested, the voltage detector may discharge tempo-
rarily the interference voltage to a level below the ELV,
but it will be back to the original value when the voltage
detector is removed.

that is expected to be disconnected of the installation, it is
highly recommended confirming by another means (e.g.
use of an adequate voltage detector, visual check of the
disconnecting point of the electric circuit, etc.) that there
is no operating voltage on the part to be tested and to
conclude that the voltage indicated by the voltage detector
is an interference voltage.
pedance has passed a performance test of managing
interference voltages and is (within technical limits) able
to distinguish operating voltage from interference voltage
and has a means to directly or indirectly indicate which
type of voltage is present.
