Function Test with Line Voltage
Applications
Functions which are relevant with regard to device safety must be
tested in accordance with the manufacturer’s recommendations,
if necessary with the support of a person who is familiar with
operation of the measuring instrument or measuring system.
Refer to SECULIFE function testers and light analyzers for further
function tests.
Measuring Method
The device under test can be subjected to a function test with line
voltage via the integrated test socket.
The function test includes the following measurements:
– Voltage U
LN
between the L and N conductors
– Load current I
L
–Active power P
– Apparent power S (calculated)
– Power factor PF (calculated cos ϕ, display > 10 W)
Power factor is calculated from active power and apparent power.
Power factor corresponds to cos ϕ for sinusoidal quantities (line
voltage and load current).
