4 Input Settings (Advanced/Options)
Valid Measurement Range (Valid Measurement Range)
his instrument switches between enabled measurement ranges. Disabled measurement ranges are skipped. For
example, when using auto range to measure the current of a device that produces 2 A when operating and 100
mA when in standby, disable the 200 mA, 500 mA, and 1 A ranges. When the device is in standby, the range will
be 200 mA. When the device begins operating, this instrument will skip the intermediate 200 mA, 500 mA, and 1
A ranges and switch directly to the 2 A range.
Valid Measurement Range (Valid Measurement Range)
Element1 to Element7
For each input element or wiring unit, you can set all ranges as valid measurement ranges (All ON).
Measurement Range Box (Left column of the list)
For each range, you can set whether the range is a valid measurement range for all input elements (All ON) or
not (All OFF).
Measurement Range to Switch to When a Peak Over-Range Occurs (Peak Over Jump)
You can specify which measurement range to switch to when the auto range feature is enabled and a peak
over-range occurs. The background of the selected measurement range turns yellow. If a peak over-range
occurs when this feature is disabled, this instrument increases the measurement range, switching between valid
measurement ranges (measurement ranges whose check boxes have been selected).
You can specify valid current measurement ranges for each input element type.
•
30A
Select the valid direct input measurement ranges of 30 A input elements.
•
5A
Select the valid direct input measurement ranges of 5 A input elements.
•
Ext Sensor
Select the valid external current sensor input measurement range.
• You cannot set all measurement ranges to off. There must be at least one valid range.
• The settings for the valid range and for the measurement range to switch to when peak over-range occurs
are shared by all the input elements in a wiring unit.
• When range Σ link is on and you change the wiring system, all measurement ranges are enabled (set to
their initial setting).
• When range Σ link is changed from off to on, all measurement ranges are enabled (set to their initial
setting).
• If you set the valid range setting for the current measurement range to OFF, this instrument switches to the
next highest measurement range. If there is no measurement range above the current one, this instrument
switches to the next lowest measurement range.
