Supports efficient operation with various types of source pattern
n Step sweep function
Sources by 25% step automatically from 0% to 100% of span
which improves efficiency of operation. It can correspond to
various response time of field devices.
(15/30/45/60 seconds)
n Manual step function
Sources by 25% step manually from 0% to 100% of span.
n Linear sweep function
Sources continuously from 0% to 100% and is capable to
check meter and make linearity tests. Sweep time can be
selected by 15/30/45/60 seconds.
