HP 16500B - Manual (Page 17)

To set the line voltage
When shipped from HP, the line voltage selector is set and an appropriate fuse is installed for
operating the instrument in the country of destination. To operate the instrument from a
power source other than the one set, perform the following steps.
1 Turn the front panel power switch to the STBY position, then turn the power switch
to the Off position. Remove the power cord from the instrument.
2 Replace the main fuse with a 5 A/250 V fuse for 230 V operation, or a 10 A/125 V fuse
for 115 V operation.
3 Set the rear panel line select switch for the desired voltage.
4 Reconnect the power cord, turn on the rear panel power switch, then continue
normal operation.
5 If your system includes an HP 16501A Expansion Frame, repeat this procedure for it.
The expansion frame has only one power switch, and that switch is located on the rear panel.
