Display Explanation
Meter mode
Meter mode is active and the Dis annunciator
should be on.
VOLT 0.00 Display indicates the default settings.
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.
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.
PROT:CLEAR Display accesses the protection menu list.
VOLT:PROT 500 Display shows the overvoltage protection trip
voltage for your unit. The overvoltage protection
voltage is programmed in peak, not rms volts.
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.
VOLT:PROT 320 Programs the OVP to a peak value that is greater
than the rms output voltage value.
Note: You cannot clear an OVP trip until you
have first removed the cause of the condition.
120 V 60 Hz Executes the PROT:CLEAR command, restoring
the output. Prot turns off and CV turns on.
