Battery Replacement
Materials needed for the HiTemp140 and PR140:
ER1425S-HT Lithium Battery
Battery Replacement Procedure:
1. Unscrew the end cap of the data logger to expose the battery.
2. Remove the battery.
3. Place the new battery into the data logger. Note the polarity of the battery.
4. Tightly screw the data logger back together until the O-Rings are no longer 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-Rings
O-Ring maintenance is a key factor when properly caring for the HiTemp140 and PR140. The O-Rings ensure a tight seal and prevent liquid from
entering the inside of the device.
Materials needed for the HiTemp140:
HiTemp140-O-Ring
Materials needed for the PR140:
PR140-O-Ring
O-Ring Replacement Procedure:
1. Unscrew the end cap from the data logger 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.
7. Tightly screw the data logger back together until the O-Rings are no longer visible.
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.
DON’T:
• Poke, jab, pry at the O-Ring with sharp or pointed objects.
• Expose the O-Rings to harsh chemicals.
• Expose the seals to high pressure (the HiTemp140 and PR140 data loggers are rated to 60 PSIG).
• Expose the seal to high temperatures (see specification for operating temperature range).
