6 HOLD
FUNCTION
This feature lets you freeze the dissolved oxygen and
temperature readings for a delayed observation.
HOLD can be used any time when in MEAS mode.
To hold a measurement, press the HOLD key while in
measurement mode. “HOLD” will appear on the
display.
To release the held value, press HOLD again.
Continue to take measurements.
NOTE: This meter shuts off automatically 20 minutes
after the last key pressed. If the meter is shut off either
automatically or manually, the HOLD value will be lost.
For longer storage, use the memory functions.
NOTE: This meter has an auto endpoint feature.
When this feature is switched on, the display will
automatically “HOLD” a reading that has been stable
for more than 5 seconds. The “HOLD” indicator
appears. Press the HOLD key to release the reading.
To switch on or off the auto endpoint feature, see
