11-2 Digital to Analog Voltage Output (DAV)
Processes the measured values from the sensors according to the values set in function modes
f-22
to
f-24
, and outputs the processed signal as a voltage after D/A conversion. The output
voltage range is from –10 V to +10 V. Scaling is available in function modes
f-22
and
f-23
.

Note on using this function
Use this mode only when adequate accuracy can not be obtained by the regular
scaling set in function modes
f-22
and
f-23
. This mode uses the internal
correction factor and requires a high-precision digital multimeter. If a low-precision
multimeter is used, it may adversely affect the indicator performance and the output
voltage accuracy.
