When FAIL LED lights
This indicates that the anti-static footwear including the human body is outside the preset range.
Check the cause and take action such as replacing the anti-static footwear.
Measurement value is lower than lower limit
Measurement value is higher than upper limit
Example: The soles of the footwear have worn down
Metal fragments are stuck in the soles
of the footwear, etc.
Example: You are wearing thick socks
The footwear itself is defective or the
soles of the footwear are dirty, etc.
Setting by DIP switches
The upper and lower limits of the pass/fail levels, sounding of the buzzer, and other parameters can be
set by switching the DIP switches on the rear of the body.
Note
Default setting is all OFF.
(Pass range is 0.1 MΩ ≤ R ≤ 100 MΩ)

Different standard values for conductive footwear, general anti-static footwear and special
anti-static footwear are stipulated in JIS T 8103.
The setting can be changed to the pass range suited to each footwear by changing the DIP
switch settings.
