FOUR : NOTE
1、The meter must be heated 15 minutes with the power on before use. (使用前,仪表需通电15分钟)
2、Avoid vibrations or shock,excessive dust and noxious gas.(注意防止震动和冲击,不要在有超量灰尘和超量有害气体的地方使用)
3、Input wire should not be too long,please use 2-core shielded cable if the measured signal input terminal is more long.(输入导线不宜过长,如被测信号输入端较长时请使用双绞屏蔽线)
4、If the input signal is super inposed with high-frequency noise, use a low-frequency filter. (若信号伴随高频干扰,应在线里使用低频过滤器)
5、If the meter won’t be used for a long time ,please connect power supply every three months, not less than 4 hours each time.(长时间存放未使用时,请每三个月通电一次不少于4小时)
6、Long time for storing the meter should be in the shade ,with the environment temperature is -25℃~55℃,the relative humidity :≤93%,and non-corrosive gas sites.(长期保存应避开直射光线,宜存放在环境温度:-25℃~55℃,相对湿度≤93% 无腐蚀气体场所)
7、If the meter no display that you should check –up the auxiliary power firstly , and the voltage should be fall within the prescribed limits.(如仪表无显示,应先检查辅助电源,电压是否在规定范围内)
8、If display is abnormal state, please check-up if the input signal working correctly and the signal terminal tightened or not.(如显示不正常,检查输入信号是否正常及信号接线端是否拧紧)
9、Except the PT has enough power , otherwise you can not use the PT signal as auxiliary power at the same time. Then can be ensure the meters working as normal.(除非PT有足够功率,否则不能使用PT信号同时做为辅助电源,以保证仪表正常工作)
10、The screw of current terminal in the CT circuit must be tightened, ensure the in-wire and out wire be reliable , so as not to cause malfunction.(CT回路中的电流接线端子螺丝务必拧紧,保证进/出线接触可靠,以免产生故障)
