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,DB5-AV20 isn't with Hi and Lo setpoint ,DB5-PAV20 is with Hi and Lo setpoint .The other models are the same
3)Attention please: With AC C.T. of the second ampere is ** that input current are bigger than **. 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 **.

9. CAUTIONS 
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 ** is superimposed with high-frequency noise,use a High-pass filter in the input ** line.
5.Input wire should not be too long. If measured ** and meter is long, please use a 2-core shielded cable, and connect its outer shite to the LO side at a ** 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
