The ESA620 Electrical
Safety Analyzer repre-
sents the next generation
in manual, portable elec-
trical safety testers. With
selections of three test
loads, protective earth
test currents, and two
insulation test voltages
this versatile product
can be used worldwide
to enhance productivity
and test to standards of
choice.
New DSP technology offers better accuracy of leakage measurements
throughout the ranges specified in the standards.
Equipped with ten safety-enhanced ECG posts, the ESA620 offers
simulation of ECG and performance waveforms so both electrical safety
and basic tests on patient monitors can be performed with a single con-
nection. When used with optional Ansur computer-based software plug-in,
the ESA620 becomes automated. This allows for standardization of test
procedures, capturing and storage of results, comparison to standard limits,
and printing of reports thus enabling the sophisticated performance of the
high-end electrical safety analyzers.
