Notes:1、If you need excition 4∽20mA Analog output meter, Please you need with"I"in forward meter, Example, DB4-PF01 isn't with 4∽20mA Analog supply output, DB4I-PF01 is with 4∽20mA Analog supply output. The other models are the same.
2、With AC C.T.of the second ampere is 5A that input current are bigger than 5A. AC P. T. of the voltage second is 100V.If input voltage are higher than 450V. |

| 6.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 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. |
