To reduce the risk of electric shock, leakage-current or resistance
measurements shall be carried out (exposed parts are acceptably
insulated from the supply circuit) before the appliance is returned to
the customer.
The DC voltage is an actual reading measured with a high imped-
ance type voltmeter with no signal input. The measurement value
may vary depending on the measuring instruments used or on the
product.
