the settings (setup) that are in use. The settings and initial values saved by this
function are listed below. Those in parentheses are initial values.

If the PCZ1000A is not turned on with the condition of the last setting when the
POWER switch was turned off, the life of back-up battery may be dead.
3.3 Load-On/Load-Off
The PCZ1000A switches between the load-on and load-off states each time the
LOAD key is pressed. If the protection function operates, the PCZ1000A goes to
load-off automatically.
• Load-on: Load current is on
The LED above the LOAD key illuminates.
• Load-off: Load current is disconnected
The LED above the LOAD key turns off.
• Risk of damage to the PCZ1000A. Only connect the output of the
equipment under test to the PCZ1000A input when it is set to the load-off
state. Do not change to load-on until after connecting. If you do connect
to the PCZ1000A input when it is in the load-on state, ensure that the
output for the equipment under test is turned off.
If a relay, electromagnetic circuit breaker, or similar is connected between
the output terminals of the equipment under test and the load input
terminals, only turn the relay or circuit breaker on when in the load-off
state and do not change to load-on until after turning on the input.
