Hiking DTS238-7 User Manual

DTS238-7 WIFI type multi-function smart energy meter is designed to measure three phase four wire AC active
energy and variable parameter. The meter have RS485 communication port and WIFI communication, it can use
APP for remote reading and control on/off. All of its functions comply with the relative technical requirement for
class 1 three phase watt hour meter in IEC62053-21 and its data communication rules obey the requirement of
MODBUS-RTU and WIFI 802.11b/g/n.It is a long life meter with the advantage of high stability , high over load
capability , low power loss and small volume .
The meter should be installed in suitable environment with ambient temperature range between-25°+55°,the
relative humidity less than 75% and temperature limits between and-40°+70°.
The meter is manufactured complying with international standard IEC62052-11 on Electricity metering
equipment (AC) General requirements tests and test conditions and IEC62053-21 on Static meters for active
energy (classes 1 and 2).
