Performing the verification test procedures
Test considerations
When performing the verification procedures:
•
Be sure to restore Model 6487 factory front panel defaults and perform voltage off-
set calibration as outlined below.
•
Make sure that the test equipment is properly warmed up and properly connected to
the correct Model 6487 terminal(s).
•
Be sure the test equipment is set up for the proper function and range.
•
Allow the input signal to settle before making a measurement.
•
Do not connect test equipment to the Model 6487 through a scanner, multiplexer,
or other switching equipment.

The maximum safe voltage between the voltage source or ammeter and
chassis ground (common mode voltage) is 505V DC. Exceeding this
voltage can create a shock hazard.
`^rqflk
Maximum continuous input voltage is 505V DC. Exceeding this value
may cause instrument damage.
Restoring factory defaults
Before performing the verification procedure, restore the instrument to its factory front
panel defaults as follows:
1.
Press SETUP. The instrument will display the following prompt:
RESTORE: FACT
2.
Using either RANGE key, select FACT then restore the factory default conditions
by pressing ENTER.
