8.7 Safety Limits Editor
The Safety Limits Editor of ES601pc-US allows you to program ES601-US with one set of alternate limits,
which can be edited or revised at any time, for each of the electrical safety standards supported by the
analyzer.
Electrical safety standards specify a limit for each measurement performed on a device under test. During a
safety test, a measured value which exceeds its corresponding limit is assigned a "fail" mark by ES601-US.
Reference tables of safety limits are incorporated into the firmware of ES601-US. There is one reference
table assigned to each regulatory standard supported by the safety analyzer. These reference or standard
tables conform to the latest revisions of the regulatory standards. For example, the standard table for
AAMI-ES1 dates from 1996.
If the equipment being tested was manufactured prior to release of the safety standard being used, limits
applied during safety tests may be inappropriate and could produce invalid failing results. To allow testing of
equipment that predates a given regulatory standard, ES601-US provides one alternate or user-defined limit
table for each of the standards. With the Safety Limits Editor, you can tailor the pass/fail limits of a
user-defined table to suit the device being tested.
Prior to starting a safety test, you can choose to apply limits according to the regulatory standard (the
"standard limits"), or you can optionally choose to apply user-defined limits to suit the equipment under
test. User-defined limits can be selected via the MANUAL MODE screen for manual measurements. Safety
AutoSequences can also be programmed to apply user-defined limits during a test sequence, via the Safety
AutoSequence Editor of ES601pc-US. When a safety test is performed, as part of the test result ES601-US
automatically saves either the standard limit or the user-defined limit for each measurement taken.
8.7.1 Editing Safety Limits
Each safety standard provided by ES601-US has its own tab in the Safety Limits Editor. To view the default
and user-defined limits for a particular standard, click on the corresponding tab at the top of the editor
window (
