Self Test Error Numbers
On the remote interface, a self–test failure will generate SCPI error –330 and a
supplemental message indicating one of the test numbers shown in the table on
page 73.
Calibration Errors
The table on page 76 shows failures that may occur during a calibration.
Electrostatic Discharge (ESD) Precautions
Almost all electrical components can be damaged by electrostatic discharge
(ESD) during handling. Component damage can occur at electrostatic discharge
voltages as low as 50 volts.
The following guidelines will help prevent ESD damage when servicing the
instrument or any electronic device.
– Disassemble instruments only in a static–free work area.
– Use a conductive work area to reduce static charges.
– Use a conductive wrist strap to reduce static charge accumulation.
– Minimize handling.
– Keep replacement parts in original static–free packaging.
– Remove all plastic, foam, vinyl, paper, and other static–generating materials
from the immediate work area.
– Use only anti–static solder suckers.
