● Maximum Operating Error
Operating error (B) is an error obtained within the
rated operating conditions, and calculated with the
intrinsic error (A), which is an error of the instrument
used, and the error (En) due to variations.

● Range to keep the maximum operating error
Measurement range within which the maximum
operating error (±30%) applies.
20Ω Range : 5 ~ 19.99Ω
200Ω Range : 20 ~ 199.9Ω
2000Ω Range : 200 ~ 1999Ω
● Temperature & Humidity
Operating : 0°C~50°C ≤ 80%R.H.
Storage : -10°C~60°C ≤ 80%R.H.
