5.2 Turning On or Off the Load
“Turning on the load” refers to the operation of supplying current to the PLZ-4W.
“Turning off the load” refers to the operation of cutting off the current to the PLZ-
4W. The LOAD key is used to turn on or off the load. Please remember the expres-
sion “turning on the load” and “turning off the load”, as they are used frequently in
