SAFETY and WARNINGS
Symbols displayed on the unit
!
Important safety information, see user manual.
The PC scopes are optically isolated from the PC, but even then it
is advisable to measure only safe devices.
⇒
Measurements should be avoided in case of polluted or very humid air.
One should also refrain from measuring conductors or installations that
use voltages that exceed 600Vrm s above ground level. CAT II indicates
conformity for measurements of domestic installations.
⇒
The maximum input voltage for the connections of the unit stands at 100Vp
(AC+DC)
⇒
Do NOT open the enclosure while performing measurements.
⇒
Remove all test leads before opening the enclosure in order to avoid
electrical shock.
⇒
Use a measuring probe with an insulated connector ( e.g. type
PROBE60S) when measuring voltages exceeding 30V.
Before making measurements and for safety reasons, it is important to know
some information about the measured unit.
Safe devices are:
•
Battery operated equipment
•
Equipment supplied via a transformer or adapter.
Unsafe devices are:
•
Equipment directly connected to mains (e.g. old TV sets)
•
Equipment that contains components that are d irectly connected to mains
(dimmers…).
It is advisable, when measuring on above equipment, to use a isolation
transformer.
Always be careful when measuring directly to the mains; please remember
that the ground of both channels is interconnected!
F
IMPORTANT: Prior to measuring high voltages, set the probe to the X10
position.
