Explanation

11.

Press ￿ or and scroll

VOLT:PROT

500

Display shows the overvoltage protection trip voltage

 

to the VOLT:PROT item

 

 

for your unit. The overvoltage protection voltage is

 

 

 

 

programmed in peak, not rms volts.

12.

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.

13.

Press Protect, scroll to

VOLT:PROT

320

Programs the OVP to a peak value that is greater than

 

the VOLT:PROT item,

 

 

the rms output voltage value.

 

and press 3, 2, 0, Enter

 

 

Note: You cannot clear an OVP trip until you have first

 

 

 

 

removed the cause of the condition.

14.

Press Protect, and

120 V 60 Hz

Executes the PROT:CLEAR command, restoring the

 

Enter

 

 

output. Prot turns off and CV turns on.

15.

Press Shift, and

CURR:LEV

5

Indicates the default output current limit setting.

 

Current

 

 

 

16.

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.

17.

Press Protect, scroll to

CURR:PROT

ON

You have enabled the overcurrent protection circuit.

 

the CURR:PROT item,

 

 

The circuit then tripped because of the output short. The

 

and press ° to select ON.

 

 

CC annunciator turns off and the OCP and Prot

 

Then press Enter.

 

 

annunciators come on. The output current is near zero.

18.

Press Output On/Off

0.5 V 60 Hz

The output is off and the Dis annunciator turns on.

19.

Press Protect, scroll to

CURR:PROT

OFF

You have disabled the overcurrent protection circuit.

 

the CURR:PROT item,

 

 

The Prot annunciator turns off.

 

press ° to select OFF,

 

 

 

then press Enter.

20.Turn the unit off.

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