CC/CV Mode Indication

Depending on the output voltage and current settings and the load circuit, the power supply

will operate in either constant voltage CV or constant current mode CC and the corresponding

LED (Item 3 or 8 in Figure 1) will be illuminated.

6.8.

Turn OFF the HV output by pushing the OUTPUT button (Item 13 in Figure 1). The ON LED

will extinguish (Item 12 in Figure 1) to show the HV output is OFF.

Wait until the output voltage has reached a safe potential, then turn off the POWER switch

(Item 11 in Figure 1).

This procedure is inherently safe, because it allows the user to observe any residual load

energy discharge and verify the output voltage is at a safe level.

Turning AC POWER OFF immediately is NOT recommended, because any residual

stored energy in the output/load may remain at a dangerously high voltage for some

time, and this voltage is not displayed on the unit's VOLTAGE meter.
