Parameter Setting Operations
3.1 Basic Parameter Setting Operations
NOTE
Set parameters only after setting the phase and wire system and the voltage range. If you change the
phase and wire system or voltage range after setting a parameter, the parameter will be initialized (to
a factory-set value). Parameters related to RS-485 and Ethernet communications will not be initial-
ized, however.
Methods of Changing Parameter Setpoints
Four setting types - integral numeric value, fixed-point numeric value, floating-point numeric value, and
selection - have been defined for the parameters of the PR300. For each setting type, the following
explains basic operations used to set parameters.
Integral numeric value or fixed-point numeric value
Using or ,
change the numeric
value.
To move to the digit to be
changed, use the following keys:
To the left
To the right
After changing the
numeric value, press
once.
Press while all
digits of the setpoint are
blinking.
Press any key other than
while all digits of the
setpoint are blinking. The
PR300 returns to the screen
in step

.
To re-set the parameter:

This confirms
the setpoint.
This causes all digits of the
setpoint to start blinking.

Floating-point numeric value
Using or ,

After changing the
numeric value, press
once.
Press while all
digits of the setpoint are
blinking.

Key operations used
to set parameters
Moves from the Measured Value
screen to the Parameter screen
(hold down the key), or confirms
the setpoint.
Shows a parameter from the menu,
moves through the digits of a setpoint
(numeric value) to the right, or moves
the decimal point to the right.
Shows the next parameter or
menu item, or changes the
setpoint.
Shows the previous parameter or
menu item, or changes the
setpoint.
Returns from the Parameter screen
to the Menu screen, moves through
the digits of a setpoint (numeric
value) to the left, or moves the
decimal point to the left.
Change the setpoint using
