Measurement modes
The meters have an Instantaneous Value Measurement mode and an
Auto Hold Measurement mode for all components of the solution being
measured.
●
Instantaneous Value Measurement mode
Instantaneous Value Measurement mode continuously displays the
measurements, as they take place. The meters perform instantaneous
value measurement as the default measurement mode when the power
is first turned ON and when the auto hold measurement is cancelled or
cleared.
●
Auto Hold Measurement mode
Auto Hold Measurement mode maintains the display of the value
measured when the meter automatically judges that the measured value
has stabilized. Press the MEAS key when in the Instantaneous Value
Measurement mode to make "HOLD" blink on the display. When the
measured value becomes stable, "HOLD" will stop blinking and remains
displayed, and the measured value will remain displayed. To clear the
hold status or "stabilized" value (when "HOLD" is blinking), press the
MEAS key.
