6.2.6 HiD 2033/2034

a) connect the power supply, 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 15

V and switch it on;

b) set the resistor box to 400 Ω; 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 2.5 K Ω; 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 750 Ω; 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 0.8

mA; switch off the supply;

f) connect the power supply, in series with the first multimeter A1 (current mode), at the input terminals; connect

the resistor box Rc at the output terminals; set the supply at 17 V and switch it on;

g) set the resistor box to 500 Ω; the input current must be within 19.40 and 20.60 mA (voltage drop test);
