Performance Verification
Determining compliance limit
The relationships to determine which compliance is in effect are summarized as follows.
They assume that the measurement function is the same as the compliance function.
•
Compliance Setting < Measurement Range = Real Compliance
•
Measurement Range < Compliance Setting = Range Compliance
You can determine the compliance that is in effect by comparing the displayed compliance
setting to the present measurement range. If the compliance setting is lower than the maximum
possible reading on the present measurement range, the compliance setting is the compliance
limit. If the compliance setting is higher than the measurement range, the maximum reading on
that measurement range is the compliance limit.
Taking the unit out of compliance
Veri
fi
cation measurements should not be made when the unit is in compliance. For purposes
of the veri
fi
cation tests, the instrument can be taken out of compliance by going into the edit
mode and increasing the compliance limit.
NOTE
Do not take the unit out of compliance by decreasing the source value or changing
the range. Always use the recommended range and source settings when performing
the verification tests.
Mainframe veri
fi
cation
Follow the procedures below to verify accuracy of the Model 6430 mainframe without the
Remote PreAmp. See
Remote PreAmp verification
later in this section for procedures on veri-
fying the complete unit with the Remote PreAmp.
NOTE
Be sure the Remote PreAmp is completely disconnected from the mainframe before
performing these mainframe verification procedures, and replace the safety cap on
the mainframe connector.
Mainframe output voltage accuracy
Follow the steps below to verify that Model 6430 mainframe output voltage accuracy is
within speci
fi
ed limits. This test involves setting the output voltage to each full-range value and
measuring the voltages with a precision digital multimeter.
1.
With the power off, connect the digital multimeter to the Model 6430 INPUT/OUTPUT
jacks as shown in Figure 18-2. (Connect Model 6430 INPUT/OUTPUT HI to DMM
INPUT HI; INPUT/OUTPUT LO to INPUT LO.)
2.
Select the multimeter DC volts measuring function.
