Constant current line regulation verification
This test measures the change in output current that results from a change in AC line voltage from
the minimum to maximum value within the line voltage specifications.
Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, never make or break connections to any of the
instruments used for this verification test while instruments are powered on. Turn off the
2260B instrument from the front panel or disconnect the main power cord from the rear of
the instrument before handling cables. Putting the equipment into an output-off state does
not guarantee that the outputs are powered off if a hardware or software fault occurs.
Precautions must be taken to prevent a shock hazard by surrounding the test device and
any unprotected leads (wiring) with double insulation for up to 800 volts depending on the
power supply that you have, Category I.
