Tests the testers
April 1st 2008 A new checkbox from
Seaward Electronic verifies
the in-service performance
of portable appliance
testers.
In keeping with advice
included in the latest IEE
Code of Practice for In-
Service Inspection and
Testing of Electrical
Equipment, the Seaward PAT
Checkbox is designed to
check the accuracy of
testers and confirm that
readings remain valid in the
period between formal recalibration.
Lightweight, portable and
easy to operate, the PAT
Checkbox can be used to
check all Seaward PATs, as
well as those from other
manufacturers.
When connected to the
tester being assessed, the
Checkbox will automatically
simulate earth bond,
insulation, flash and earth
leakage tests. A comparison
of the value displayed on
the PAT against the
specified limits detailed on
the Checkbox provides an
immediate indication of the
accuracy of the instrument. More articles from Seaward Electronic Ltd: |
