Battery Replacement
Materials needed: TLH-5903 Replacement Battery
Procedure:
1. Unscrew the end cap from the logger.
2. Grasp the circuit board firmly on either side of the battery holder with one hand and pull
the battery out of the holder with the other.
3. Install the new battery as shown by the diagram on the bottom of the battery holder.
4. Screw the body of the logger back together making sure the O-Rings are not visible.
Battery Warning
DISCARD USED BATTERY PROMPTLY. KEEP OUT OF REACH OF CHILDREN. DO NOT DISPOSE OF IN FIRE,
RECHARGE, PUT IN BACKWARDS, DISASSEMBLE, OR MIX WITH OTHER BATTERY TYPES. MAY EXPLODE,
FLAME, OR LEAK AND CAUSE PERSONAL INJURY.
O-Ring
Part Number: RFOT-O-Ring
Procedure:
1. Unscrew the end cap from the RFOT to expose the O-Ring.
2. Use a small pointed tool (knife or pick) to pry the old O-Ring out of its groove.
3. Make sure that the O-Ring groove is free of any dirt or debris.
4. Partially screw the mating parts back together leaving the O-Ring groove exposed.
5. Apply a thin coat of silicone based lubricant to the O-Ring.
6. Stretch the O-Ring over the cap and into its groove.
WARNING: Avoid stretching the
O-Ring over the threads! Sharp threads can cut the new O-Ring!
Maintenance:
MadgeTech data loggers come directly from the factory with high quality O-Rings that have been properly installed. As a user, there are only a
few things that need to be remembered to maintain a functional O-Ring seal.
DO:
• Clean them frequently (use compressed air or a soft brush to avoid abrasion).
• Lubricate regularly (if it doesn’t feel slippery, it needs to be lubricated). We recommend Parker
® Super-O-Lube, but any silicone based
O-Ring lubricant will work. This is most important on the seals that are frequently opened and closed for communication with the logger.
• Inspect the O-Ring regularly for signs of failure (see the reverse side of this pamphlet for details on what to look for)
Desiccant Packet
Located on the board of the RFOT is a desiccant packet. The desiccant packet should be left in the case as it is supplementary protection
against any additional moisture.

DON’T:
• Poke, jab, pry at the O-Ring with sharp or pointed objects.
• Expose the O-Rings to harsh chemicals (when in doubt, call MadgeTech).
• Expose the seals to high pressure (all of MadgeTech’s submersible data loggers are rated to 60 PSIG).
• Expose the seal to high temperatures (see data logger Specification Sheet for operating temperature range).
Recalibration
Recalibration is recommended annually for all MadgeTech data loggers. The Properties window in the MadgeTech 4 software displays
the date of the last calibration and the date that the device is next due for calibration. The MadgeTech 4 Software can also be
configured to send an on screen notification prior to the calibration due date for each device. By default this is set to seven days prior
to calibration due date and can be changed by the user by going to the file tab in the MadgeTech 4 software and clicking on Options.
Select device and check “Display popup notification when a device nears its next calibration date”. The user can then select the
number of days before calibration due date to notify.
Use the RMA system to submit the device for recalibration (see below).
