The MicroFID II has the ability to change log modes without erasing the log. In other words, if
the user switches User modes from Interval mode to Location mode the previous Interval log
entries are NOT erased as in older style instruments.
The MicroFID II also operates in a ‘circular-logging’ mode. This means that the log will never fill
and stop logging but will loop back to the first entry and start logging at entry number 1.
Interval Mode - Data Logging
Interval mode logs readings at user selected intervals of 1 second to 999 seconds. The
microprocessor accumulates all readings in an averaging interval that you select, and
determines the average reading. It stores this number along with the highest priority instrument
status and the current time and date.

Location Operation
– Data Logging
In the Location mode of operation, data is logged only when the ‘accept’ soft key on the probe
trigger is pressed. The date, time, average reading at the time the trigger is pressed, along with
the current tag string that is currently on the display are also stored.
Clearing or Downloading Data
There are two options for data manipulation under the Data Log Options selection.
The first option
is the “Clear Data Log” option which deletes all readings in the MicroFID II
memory.
NOTE: Deleted information cannot be recovered. You should download the contents of the
datalogger before deleting any information.
