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¡æ to 40¡æ,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. |
