11. Turn off AC power, and remove all connections to the remote analog
control connector (J1), except the jumper between Pins J1-5 and J1-6;
ensure that they are jumpered to enable the output, and allow front panel
control.
4.2.4 Change Calibration Date
To change the calibration date stored in memory, issue the following SCPI
commands (see SG Series Programming Manual for command details)
through the remote digital interface, either RS-232, GPIB, or Ethernet:

Calibration and Verification Procedures
6.
CAUTION!
Hazardous voltages may be present on the output, even after it is
disabled, due to stored capacitive charge. Disconnect the mains AC
input, and allow 5 minutes to drain the output capacitive charge to
safe levels before connecting or removing output wiring.
4.3.1 Constant-Current Mode
1. Disconnect AC mains power to the unit. Setup the SGI Series unit to
operate with remote current programming using an external 0-5 VDC
voltage-source, as shown in Figure 3-15 in Section 3.10. Ensure that Pins
J1-5 and J1-6 are jumpered to enable the output.
