5. ROUTINE MAINTENANCE
The following section outlines the procedures for proper maintenance of the MicroFID II.
Maintenance Intervals
Maintenance intervals are a function of the total use of the instrument and can be broken down
into the cumulative hours that the unit has been used and the need to ensure proper running
performance of the unit.
It is advised that the MicroFID II should have filters changed and an inspection calibration
performed at least once a month along with daily calibrations of the unit before use in the field.
Of course, filter change-out and calibration are a function of use in the field, conditions of the
sampling environment (dusty, etc.) and the critical nature of the measurements.
Battery Charging
The MicroFID II battery pack must be charged for 8 to 12 hours prior to using the instrument to
ensure proper charge/discharge timing with future uses.
A fully charged battery powers the MicroFID II for approximately 15 hours.
When the instrument status displays “Low Battery Error!”, the battery pack requires charging.
When the “Low Battery Error!” status is displayed, you have a few minutes of operation left. The
MicroFID II will turn itself off before the battery pack becomes critically low.
CAUTION: Do not connect the battery charger to the MicroFID II in a hazardous location.
Upon return from field work, charge the battery pack as outlined in Chapter 2. You will need one
charger for each battery pack. Use only the MicroFID II battery charger.
NOTE: Do not leave battery packs uncharged for an extended period of time. This will result in
damage to the battery packs.
The charger automatically charges at a high charge rate until the battery pack is fully charged. It
then maintains the full charge with a low continuous charge rate indefinitely so there is no
danger of over-charging.
NOTE: Leaving the MicroFID II for more than 3 months without turning it on may result in the
loss of recorded data and setup parameters. If the MicroFID II is not used for long periods of
time, turn on the instrument for a few hours every month to avoid loss of data.
