2.6.2.8 Limit
In the case where I (current) is selected rather
than R (resistance), the exponent would be
entered as a negative number.
Figure 2-15: Limit Value (Resistance or Current)
Allows entry of a single measurement limit in scientific units (up to 4 digits with decimal
and exponent) for resistance or current, depending on the results parameter selected. The
exponent must be 3 through 14 for resistance or -3 through -13 for current. This limit de-
termines the status of the Pass/Fail indicator and Pass/Fail display, when enabled. When
the 2408 instrument is in the Resistance mode, the limit is a minimum value, i.e. any value
above the limit will result in a Pass, whereas a value below the limit will result in a Fail. The
opposite is true when the unit is in the current mode: the limit is a maximum value; any
value below the limit will result in a Pass and a value above the limit will result in a Fail.
If the display parameter on the I/O Menu is selected as resistance, the value entered will
be an R limit; if the display is selected as current, the value entered will be an I limit. The
2408’s software will check for consistency between the parameter display selected and the
limit entered.
