Measurement Accuracy
● Overview
The measurement accuracy is tested using two different* integral times.
* But only one integral time is used when using the MV2000 with the /MC1 option.
The measurement accuracy test is performed in one of the following ways.
• One representative channel for each A/D converter is tested, and the channel-to-
channel error between the representative channel and other channels is tested (see
next page).
* Choose any channel number for each A/D from those listed in the A/D converter
configuration table.
Ex.: With the MV1004, set channels 1 and 3 as representative channels.
• The measuring accuracy of all channels is tested separately.
