Rule and Rate

Not available for voltage measurement or fixed ranging. See

also

“Enhanced Auto Ranging for Current Measurement” on

page 4-58.

Available Range Change Rule values are BY FULL RANGE,

GO UP AHEAD, and UP AND DOWN AHEAD.

BY FULL RANGE performs normal auto ranging operation.

For the GO UP AHEAD and UP AND DOWN AHEAD rules,

specify the Rate value, 11 to 100, which fixes the boundary of

the ranging. The ranging occurs when the measurement data

goes across the boundary values shown below.

go up boundary = present measurement range  Rate / 100

go down boundary = present measurement range  Rate / 1000

The go down boundary is available only for the UP AND

DOWN AHEAD rule.

Up Moves the selected measurement channel setup upward.

Down Moves the selected measurement channel setup downward.

If multiple measurement channels are defined, the channels perform measurement

sequentially. The order is top to bottom of the channels defined in this screen. For

exceptions and details, see

“Multiple Measurement Channels” on page 4-69.
