Figure 22: Remove the Old Battery and O-ring
Install the Replacement O-ring and Battery
Whenever you open a Logger, you need to replace the cup O-ring to ensure
that the Logger maintains its seal. The ValProbe RT battery replacement kit
contains two types of O-rings.
• For temperature ranges from –85 to 140ºC, use the orange (silicone material)
O-ring.
• Before you install a new O-ring, you need to apply a thin coat of grease to the
O-ring (see warning above regarding KRYTOX grease). Carefully apply the
grease to all surfaces of the O-ring, ensuring not to cut or scratch the O-ring.
Figure 23: Apply Grease and Replace O-ring
• Slide the O-ring over the tip end of the probe and into the O-ring groove. Do
not stretch or deform the O-ring and avoid contact with the threads to prevent
nicking and/or cutting the O-ring.
• With the new O-ring in place, insert the pre-conditioned battery into the battery
holder and place the battery cap on top and turn the cap down and clockwise
to lock it into place.
• Once the battery is installed, a small red LED on the top edge of the board
blinks three times to confirm that the Logger is powered on. If the LED light
does not blink, follow the important note below to troubleshoot.
