taking the final reading. After the reading is taken, push the sensor actuator back into
the dry-down position.
Note that when the instrument is being operated on a battery it will shut off automatically
if no buttons are pressed for: 6 minutes when sensor is in the sample chamber (the out
position), or 3 minutes when sensor is in the desiccant.
The unit does not have to be “on” while waiting for purging or stabilization.
