The power sup plies are fac tory cal i brated and nor mally need no fur ther cal i bra tion.
Me ter cal i bra tion
The full scale in di ca tion of the volt me ter can be cal i brated with trimpotmeter R480.
The full scale in di ca tion of the Cur rent me ter can be cal i brated with R490.
In su la tion
For safety the in su la tion of the seperating com po nents (trans form ers) be tween in put and out put is tested at 3750
Vrms dur ing 1 min ute. This is tested be fore as sem bly.
Warn ing! The 3750 Vrms can not be tested af ter wards on the as sem bled unit be cause the in su la tion be tween the
com po nents on the in put side to the case (like the bridge rec ti fier) is spec i fied at 2500 Vrms.
Since the in su la tion out put - case is low (only 600 VDC) the in su la tion of the pri mary com po nents to case will break
down when 3750 Vrms is ap plied be tween in put and out put (2500 Vrms + 600 VDC <3750 Vrms)
(see also the fig ure be low).
