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
