	Procedure	Display	Explanation
6.	Press 5, Enter	VOLT:PROT 5	Programs the OVP to 5 volts, which is less than
			the previously set output voltage.
		0.449V 0.145A	Because the OVP voltage entered was less than
			the output voltage, the OVP circuit tripped. The
			output dropped to zero, CV turned off, and Prot
			turned on.
7.	Press Shift, OV,	VOLT:PROT <22>	Programs the OVP to a value greater than the
	<2, 2>, Enter		output voltage setting of the unit. This prevents
			the OV circuit from tripping again when the
			protection condition is cleared.
8.	Press Shift, Prot Clear	<20.003V>	Clears the protection condition, thus restoring
		0.0034A	the output of the unit. Prot turns off and CV
			turns on.

9.Press Output on/off

10.Connect a jumper wire across the + and - output terminals.

Turn the output off.

Shorts the output of the unit.

11.	Press Output on/off.	0.0005V		The CC annunciator is on, indicating that the
		<0.5005>A		unit is in constant current mode. The unit is
				sourcing output current at 10% of the maximum
				rating (the default output current limit setting).
12.	Press Current, <5>,	0.0452V		Programs the output current to the selected
	Enter.	<5.002>A		amperes.
13.	Press Shift, OCP	0.0005V	0.0003A	You enabled the overcurrent protection circuit.
				The circuit then tripped because the unit was
				operating in constant current mode. The CC
				annunciator turns off and the OCP and Prot
				annunciators come on.
14.	Press Shift, OCP	0.0005V	0.0003A	You have disabled the overcurrent protection
				circuit. The OCP annunciator turns off.
15.	Press Shift, Prot Clear	0.0452V		Restores the output. The Prot annunciator turns
		<5.002A>		off. CC is on.
16.	Turn the unit off and			The next time the unit turns on it will be
	remove the shorting wire			restored to the *RST or factory default state.
	from the output terminals.
