Default: 20 A
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.”
