ADW300 Wiring instructions
Main Functional Characteristics
It can measure all power parameters including voltage U, current I, active power P, reactive power Q, apparent power S, power factor PF, phase angle of voltage and current Φ, voltage unbalance, current unbalance, frequency F, 2-31st fractional harmonics, odd and even total harmonics and total harmonics. Voltage U reserved 1 decimal, frequency F reserved 2 decimal, current I reserved 3 decimal, power P reserved 4 decimal, phase angle Φ reserved 2 decimal, unbalance reserved 2 decimal.
Supporting 4-channel temperature measurement and residual current monitoring
Communication protocol
The instrument adopts MODBUS-RTU protocol or DL/645 protocol. For specific protocol formats, please refer to the relevant protocol standards.
Common errors check and solve
1 The meter do not light after powered, or one path of voltage indicator do not light.
Suggestion: Please turn the screw to ensure that the meter needle has been punctured and contacted with the cable inner
conductor cable.
2 Meter’s wireless communication failure
Suggestion: Please connect RS485 interface on the meter and USB convert to 485 serial port to read the parameters, and
confirm whether the parameters are the same as the upper terminal wireless configuration (channel and spread spectrum
factor). If different, please modify the meter’s wireless parameters and retest the master terminal after the same, and if
the same, it may be the meter and master terminal are in a relative long distance. It is too far to communicate or the scene
is seriously disturbed. We can try to use the external antenna at the same time, or consider the newly added wireless
master terminals, and then test it.
