6.6 Turning the Output On and Off
WARNING
Never touch the terminals or cables when the 2558A output is on. Doing so may cause electric
shock.
AVERTISSEMENT
Ne touchez jamais les bornes ou les câbles lorsque la sortie du dispositif 2558A est sous
tension. Ceci risquerait d’entraîner un choc électrique.
Procedure
Flip the
OUTPUT
switch up.
The output turns on, the ON indicator illuminates, and the OFF indicator turns off. Flipping the OUTPUT
switch while the output is on will turn off the output and the ON indicator and turn on the OFF indicator.
When the output is on, the frequency output value is displayed.
Display example of 65Hz
Turn the output on
or off.
Unit
Note
When outputting current from the current terminals, do not open the current terminals.
When outputting voltage from the voltage terminals, do not short the voltage terminals.
If you do, the overload protection function will be activated, an error code will be displayed, and the output
will be turned off.
Explanation
Turning the Output On and Off
When you turn on the output, if a voltage range is selected, the 2558A outputs voltage from the voltage
terminals. If a current range is selected, the 2558A outputs current from the current terminals.
If you change the voltage or current range, the output automatically turns off.
