changed
The "CHANGED" message is displayed for a second to show that the new OVP trip level is now in effect. If the OVP settings are not changed, "NO CHANGE" will be displayed. The power supply will exit the OVP menu and the display will return to the meter mode. Check that the OVP annunciator turns on.
Checking OVP Operation
To check OVP operation, raise the output voltage to near the trip point. Then very gradually increase the output by turning the knob until the OVP circuit trips. This will cause the power supply output to drop to near zero. The OVP annunciator is blinking and the CC annunicator turns on. The "OVP TRIPPED" message also appears on the display.
Clearing the Overvoltage Condition

Over Voltage
When the OVP circuit trips (the "OVP TRIPPED" message is shown on the display), the OVP annunicator blinks. When it was caused by external voltage source such as a battery, disconnect it first. The following steps show how to clear the overvoltage conditions and get back to normal mode operation. In the following steps, the display will go back to "OVP TRIPPED" if you let the display time out after about several seconds.
