[DC voltage (0 to 5 V DC, 0 to 10 V DC)]
If the input to the input terminals of the instrument is 1 V DC and if
the value corresponding to 1 V DC is indicated, the instrument is
likely to be operating normally, however, the signal wire may be
disconnected.
[Direct current (0 to 20 mA DC)]
If the input to the input terminals of the instrument is 1 mA DC and
if the value corresponding to 1 mA DC is indicated, the instrument
is likely to be operating normally, however, the signal wire may be
disconnected.
• Check whether the input lead wire terminals for DC voltage (0 to 5 V
