INTRODUCTION
MEWOI-CKT9930A/31A ground continuity tester can output test current DC 10~100A (only CKT9931A), ground resistance test range 0.1μΩ~600mΩ, stable test and high accuracy. With test line abnormality detection function, there are 6 groups of test modes, which can realize programmable test and sorting. RS485 interface is optional, and instrument networking can be easily realized through MODBUS communication protocol. Comply with photo voltaic standards IEC61215, IEC61730. |
FEATURES
· Simultaneous display of test current, test resistance and test time ·Constant current linear amplification output ·Test time can be set arbitrarily ·Sound and light alarm function |
