1)If you need excition 4~20mA Analog output meter, Please you need with "I" in forward meter. Example, DB3-AV20 isn't with
4~20mA Analog supply output, DB3I-AV20 is with 4~20mA Analog supply output. The other models are the same.
2)If you need excition Hi and Lo setpoint meter, Please you need with "P" in meter model. Example,DB3-AV20 isn't with Hi
and Lo setpoint, DB3-PAV20 is with Hi and Lo setpoint. T he other models are the same.
3)Attention please: With AC C.T. of the second ampere is 5A that input current are bigger than 5A. And AC P.T. of the voltage
second is 100V, if input voltage are higher than 1000V.
4)Attention please: With DC Shut Resistor of the second voltage is 75mV that input current are bigger than 5A. |

1.The meter must be heating 15 minutes with the power on before use.
2.Use in ambient temperatures of 0℃ to 40℃,humidifies of 85% R.H.
3.The meter alignment interval time is one year.
4.If the input signal is superimposed with high-frequency noise,use a High-pass filter in the input signal line.
5.Input wire should not be too long. If measured signal and meter is long, please use a 2-core shielded cable, and connect its outer shite to the LO side at a signal soure.
6.If the digit meter relay is not used for a long time. Please counect power supply once every three months, not less
than 4 hours each time. |
