a) connect the power supply at the termination board supply terminals; connect the first multimeter A1 (current
mode) at the input terminals, in series with the resistor box Rc; feed the supply voltage to the output terminals,
with the second multimeter A2 (current mode) in series; set the supply at 24 V and switch it on; the green power
LED must go on;
b) set the resistor box to 780 Ω; the input current must be within 19.50 and 20.50 mA; the output current must be
the same, with an error lower than 20 µA; the red Fault LED must be off
c) set the resistor box to 5 KΩ; the input current must be within 3.50 and 4.50 mA; the output current must be the
same, with an error lower than 20 µA; the red Fault LED must be off
d) set the resistor box to 1500 Ω; the input current must be within 11.50 and 12.50 mA; the output current must be
the same, with an error lower than 20 µA; the red Fault LED must be off
e) set the resistor box to 0 Ω; the (short-circuit) input current must be within 25 and 30 mA; the output current must
be the same, with an error lower than 100 µA; the red Fault LED must be on
f) disconnect the resistor box; the (open-circuit) output current must be lower than 1 mA; the red Fault LED must
be on
