This is a universal measurement network.
Measurement network D conforms to the following standards:
Safety of household and similar electrical appliances - Part 1: General
requirements (IEC 60335-1 (1991-06) + am1 (1994-11))
Applicable UL standards:
By installing on the 3155 and making the appropriate settings from the
screen, a configuration with a network of 1 k
Ω for 1 k Ω , a network of 1.5 k Ω
and 0.15 μ F for 1.5 k Ω , and a network of 2 k Ω for 2 k Ω is established.
In addition, there are many applicable standards.
