	Procedure	Display		Explanation
1.	Turn the unit on.	Meter mode		Meter mode is active and the Dis annunciator
				should be on.
2.	Press the Voltage key.	VOLT	0.00	Display indicates the default settings.
3.	Press 1, 2, 0, Enter	VOLT 120		Programs the output voltage to 120 Vrms. After
				the value is entered, the display returns to Meter
				mode, which indicates that no voltage is applied to
				the output.
4.	Press Output On/Off	120 V	60 Hz	Turns the output on and applies 120 volts to the
				light bulb. The Dis annunciator should be off and
				CV should be on.
5.	Press Protect	PROT:CLEAR		Display accesses the protection menu list.
6.	Press ￿ or  and	VOLT:PROT 500		Display shows the overvoltage protection trip
	scroll to the			voltage for your unit. The overvoltage protection
	VOLT:PROT item			voltage is programmed in peak, not rms volts.
7.	Press 1, 6, 0, Enter	VOLT:PROT 160		Programs the OVP to 160 Vpeak, the rms value of
				which is less than the previously set rms voltage.
		0 V 60 Hz		Because the peak OVP voltage entered was less
				than the rms output voltage, the OVP circuit
				tripped. The output dropped to zero, CV turned
				off, and Prot turned on.
8.	Press Protect, scroll	VOLT:PROT 320		Programs the OVP to a peak value that is greater
	to the VOLT:PROT			than the rms output voltage value.
	item, and press 3, 2, 0,			Note: You cannot clear an OVP trip until you
	Enter			have first removed the cause of the condition.
9.	Press Protect, and	120 V	60 Hz	Executes the PROT:CLEAR command, restoring
	Enter			the output. Prot turns off and CV turns on.
