Product description
Product parameters
Reference standard: GB7216-2008, DL/T995-2006.
Features:
● Test various AC/DC, current, voltage, intermediate, self-holding, signal and other single relays and the entire set of relay protection screens;
● Test the pull-in voltage （current） value of various relays, release voltage （current） value, pull-in time and disconnection time of various contacts （normally open, normally closed, converted, delayed）;
● With microcomputer control, there are only 16 touch switches on the panel, which can easily complete various test functions.
