6.2.5 HiD 2031/2032

a) connect the power supply at the termination board supply terminals; feed the supply voltage, in series with the

first multimeter A1 (current mode) and with the resistor box Rc, at the input terminals; connect the second

multimeter A2 (current mode) at the output terminals; set the supply at 24 V and switch it on; the green power LED

must go on;

b) set the resistor box to 1.1 KΩ; the output current must be within 19.50 and 20.50 mA; the input current must be

the same, with an error lower than 20 µA;

c) set the resistor box to 5.6 KΩ; the output current must be within 3 and 5 mA; the input current must be the

same, with an error lower than 20 µA;

d) set the resistor box to 1.8 KΩ; the input current must be within 11 and 13 mA; the output current must be the

same, with an error lower than 20 µA;

e) disconnect the multimeter A2 at the output terminals; the (open-circuit) input current must be lower than 1.2

mA;
