To Construct Your Own Dummy Load - HP 54616B User And Service Manual

To construct your own dummy load

Obtain a connector compatible with the connector J3 on the Low
1
Voltage Power Supply (see figure below).
Connect the following load resistors to the connector.
2
+5.1 V requires a 4 A load, 1.3 Ω and 20.4 W on pins 9–12.
–5.25 V requires a 3 A load, 1.75 Ω and 15.8 W on pins 15–18.
+15.75 V requires a 1.3 A load, 12.2 Ω and 20.5 W on pins 5–6.
–15.75 V requires a 0.8 A load, 19.7 Ω and 13 W on pin 3.
Connect the other end of the resistors to ground pins 2, 4, 7, 8, 13, 14,
3
19, and 20.
