Carrying out voltage measurement AC
In order to avoid electrical shock, the valid
safety and VDE regulations regarding excessive
contact voltages must receive utmost attention,
when working with voltages exceeding 120 V
(60 V) DC or 50 V (25 V)rms AC. The values in
brackets are valid for limited ranges e.g., medici-
ne and agriculture).
Attention
The voltage tester is appropriate for AC voltages
between 50 V and 600 V AC. A perfect instrument
function is only ensured within a temperature
range of 0 ... 40°C, <80 % humidity.
Attention
The instrument may not be used to prove the
absence of voltage in electrical systems. When
working with sheathed conductors or instru-
ment, the indirect voltage test (contact-free) is
either impossible or only feasible considering
certain restrictions.
Contactless (indirect) voltage testing
This kind of measurement is possible with switch
pos. 1 + 2 and covers contactless voltage detec-
tion of insulated cables, leads or instruments
which send electric magnetic fields. In addition
cable interruptions can be detected.
When testing mains connecting cables for inter-
ruptions the user must ensure that both lines are
connected to phase (L). (Turn plugs by 180°).
