10.	Press Shift, and	CURR:LEV	5	Indicates the default output current limit setting.
	Current
11.	Press . 5 Enter	CURR:LEV	.5	Sets the current limit to .5 amperes. The CC
				annunciator is on, indicating that the unit is in
				current limit mode and the light bulbs are dimmer
				because the output voltage has dropped in its
				attempt to limit output current.
12.	Press Protect, scroll to	CURR:PROT ON		You have enabled the overcurrent protection
	the CURR:PROT item,			circuit. The circuit then tripped because of the
	and press ° to select			output short. The CC annunciator turns off and
	ON. Then press Enter.			the OCP and Prot annuciators come on. The
				output current is near zero.
13.	Press Output On/Off	0.5 V 60 Hz		The output is off and the Dis annunciator turns on.
14.	Press Protect, scroll to	CURR:PROT	OFF	You have disabled the overcurrent protection
	the CURR:PROT item,			circuit. The Prot annunciator turns off.
	press ° to select OFF,

then press Enter.

15.Turn the unit off.

The next time the unit turns on it will be restored to the *RST or factory default state

In Case of Trouble

Error Messages

Ac source failure may occur during power-on selftest or during operation. In either case, the display may show an error message that indicates the reason for the failure.

Selftest Errors

Pressing the Shift and Error keys will show the error number. Selftest error messages appear as: ERROR <n>, where "n" is a number listed in the following table. If this occurs, turn the power off and then back on to see if the error persists. If the error message persists, the ac source requires service.
