Accuracy calculation
Example: DCV function
True value: 100 mV
Range accuracy: 400 mV range …±(0.5 %rdg+2dgt)
Error: ±(100.0 mV x 0.5 % + 2dgt) = ±0.7 mV
Indicated value: 100.0 mV ± 0.7 mV (in a range of 99.3 mV and
100.7 mV)
The product specifications described in this manual and its
appearance are subject to change without notice for improvement or
other reasons.
* Accurate measurement may not be possible in places near a
transformer, large-current line, etc. where a strong magnetic field
is present or near radio equipment, etc. that generates a strong
electric field.
