ET613 ET612 Network Cable Tester Wire Tracker Continuity Battery Voltage Polarity Check POE Multi-Function Test Cable Tester
Feature
303D communication maintenance power supply is a single line output of stabilized high accuracy
DC stabilized power supply. The output voltage and current can be adjusted continuously within the
rated range. The load current has MA conversion with two settings: 0-3A and 0-99 mA. Constant
voltage and constant current (CV/CC), automatic switching of working modes. Double digital display
shows output voltage and current independently. Several protection functions include current
limitation, voltage reduction, short circuit protection, over-temperature protection, etc. The design
is applied to production line of the plant, maintenance, laboratories and is also a necessary device
for the communication industry.
UT350 series digital sound level meter with stable performance, safety and reliability can be widely used for environmental protection, laborhygiene, industrial enterprise, scientific research and teaching. It is applied to environmental noise measurement, machinery equipment noise measurement and architectural acoustics measurement.
