6.2 Changing Voltage Range Setting
● Procedure to Change Voltage Range Setting
(1) The
sign is displayed uppermost on the screen, under the voltage
range currently selected. To change the range, press the
key when
the measurement screen is displayed.
V
RANGE
150V 300V 450V
Voltage ranges
V RANGE key
Each press of the key changes the range selection sequentially as
follows:
150 V 300 V 450 V
Default: 150 V
TIP
• If a change to the range setting is incompatible with the conditions derived from other settings,
is displayed and the change is ineffective. First change other settings such as the current range, VT
ratio, CT ratio, and wiring method, then change the voltage range.
• The voltage range cannot be changed during continuous measurement.
• The voltage range cannot be changed when the electric energy count is not zero. Pressing the
key at this time causes to appear on the screen (this will disappear and the measurement
screen will return when any key is pressed). Clear the electric energy count first. For details of how to
do this, see Section 9.2.3, “Clearing Electric Energy Count,” or Section 7.2.4, “Clearing Electric Energy
Count and Resetting System,” in Chapter 7, “Making Settings.”
