Marking  Instructions

MSR12A is marked with four digit(Ref to Fig.1). We have two different ways of marking:

a. “ R” designates the decimal location in ohms 

e.g. 2mΩ : R002;       10mΩ : R010;

b. “m” designates the decimal location in milliohms 

e.g. 2.5mΩ : 2m50;    5.5mΩ : 5m50;

MSR08A is marked with three digit(Ref to Fig.2). We have two different ways of marking:

a. “ R” designates the decimal location in ohms 

e.g. 2mΩ : 002;        10mΩ : 010

b. “m” designates the decimal location in milliohms

e.g. 2.5mΩ : 2m5;     5.5mΩ : 5m5 MSR06A no marking.

Storage

The temperature condition must be controlled less than 40℃,  The R.H. must be controlled    less than 75%. Store in accordance with this requirement, and the validity period is two years after the date of manufacture.

Please avoid the mentioned harsh environment below when storing to ensure product

performance and its’ weldability. Places exposed to sea breeze or other corrosive gas, such as Cl2 , H2S, NH3 , SO2  and NO2 .

When the product is moved and stored, please ensure the correct orientation of the box. Do not drop or squeeze the box. Otherwise, the electrode or the body of the product may be

damaged.
