Indicator-out mode
The indicator-out mode is designed to turn off the PR300 display when no key operation is performed
within the indicator-out mode wait time that has been set while measured values are on display. The
PR300 switches to the Measured Value screen in about 5 minutes when no key operation is performed
while the Parameter screen is on display. Then, the PR300 display turns off after the elapse of the
indicator-out mode wait time from when the PR300 switched to the Measured Value screen.
To turn on the PR300 display to show measured values during indicator-out mode, press any key.
Locking and Unlocking Parameters
Executing the following operations locks or unlocks all parameters. (A parameter cannot be locked or
unlocked individually.) If a parameter is locked, it will be impossible to shift to the Parameter Setting screen.
Use the Parameter screen showing the current value or the Menu screen to lock or unlock parameters.
Operations used on an individual parameter setting screen or on the Measured Value screen in an attempt to
lock parameters will have no effect.
