Performance Verification
Setting the source range and output value
Before testing each veri
fi
cation point, you must properly set the source range and output
value as outlined below.
1.
Press either the SOURCE V or SOURCE I key to select the appropriate source
function.
2.
Press the EDIT key as required to select the source display
fi
eld. Note that the cursor
will
fl
ash in the source
fi
eld while its value is being edited.
3.
With the cursor in the source display
fi
eld
fl
ashing, set the source range to the lowest
possible range for the value to be sourced using the RANGE
▲
or
▼
key. For example,
you should use the 20V source range to output a 20V source value. With a 20V source
value and the 20V range selected, the source
fi
eld display will appear as follows:
Vsrc:+20.0000 V
4.
With the source
fi
eld cursor
fl
ashing, set the source output to the required value using
either:
The SOURCE
▲
and
▼
and and keys.
The numeric keys.
5.
Note that the source output value will be updated immediately; you need not press
ENTER when setting the source value.
Setting the measurement range
When simultaneously sourcing and measuring either voltage or current, the measure range is
coupled to the source range, and you cannot independently control the measure range. Thus, it
is not necessary for you to set the measure range when testing voltage or current measurement
accuracy.
Compliance considerations
Compliance limits
When sourcing voltage, you can set the unit to limit current from 1fA (with PreAmp) to
105mA. Conversely, when sourcing current, you can set the unit to limit voltage from 0.2mV to
210V. The instrument output will not exceed the programmed compliance limit.
Types of compliance
There are two types of compliance that can occur:
“
real
”
and
“
range.
”
Depending on which
value is lower, the output will clamp at either the displayed compliance setting (
“
real
”
) or at the
maximum measurement range reading (
“
range
”
).
