(range expand)
The transmitter provides an isolated 4-20 mA analog output.
During normal measurement operation, the output is active
but can be held at the last measured value for up to 30 min-
utes by using the “HOLD OUTPUT” function in the
TEST/MAINT menu. (See PART THREE, Section 5.2 for
details.) During calibration, the output is automatically held
at the last measured value and, upon completion, returned
to its active state.
The output can be assigned to represent the SENSOR
(measured conductivity, resistivity or TDS) or measured
TEMPERATURE.
