九、注意 CAUTIONS
1.使用前，仪表需通电预热15分钟。The meter must be heated 15 minutes with the power on before use.
2.适宜使用环境温度0~40度，相对温度85%下。Use in ambient temperatures of 0 to 40,humidity less than 85%R.H
3.本仪表校准时间间隔为一年。The meter alignment interval time is one year.
4.注意防止震动和冲击，不要在有超量灰尘和超量有害化学药品和气体等地方使用。
Avoid vibrations or shock,excessive dust,corrosive chemical materials or gas.
5.若输入信号伴随高频干扰，应在线里用高频过滤器。
If the input signal is super imposed with high-frequency noise,use a low-passed filter.
6.输入导线不宜过长，如被测信号输出端与仪表距离不能缩短，请用双绞屏蔽线，屏蔽层与信号低端相连。
Input wire should not be too long,If measuredsignal have to be faraway from the meter,pleas use 2-core shielded cable,
connect its shield lager to the LO side of the signal soure.
