PRODUCT HIGHLIGHTS:

- Six Group of 10-decade switches (100kΩ~111.111GΩ)
- SB2015-3A Precision Decade DC Resistance Box adopts high voltage glass glaze resistors and special high voltage seal switch. - - Its electric performance is very stable, and insulation intension is very high. 
- The resistance value can be adjusted under the condition of ceaselessly opening voltage. (Note: The using of switch should not be at point of "0".) 
- It is easy to operate and suitable to be used to calibrate insulation resistance meter, and suitable to be used as high resistance standard.
