Replacing the INTERCAP
®
Sensor on
Outdoor Models HMS82/83
REQUIRED
TOOLS
- New INTERCAP
®
humidity sensor.
- New filter (always recommended when replacing the sensor).
- Medium size crosshead screwdriver (Pozidriv)
- Flat head screwdriver
- 3 mm hex key (Allen key) for opening the radiation shield screws.
- If transmitter mounted on pole: 2.5 mm hex key for opening and
tightening the set screw.
NOTE
You will need to remove the radiation shield to access the sensor, and
this is difficult to do while the transmitter remains mounted on a pole or
wall. The procedure below takes advantage of the detachable screw
terminal to allow the cable to remain in place during the operation.
1. Power down the transmitter.
2. Open the transmitter cover and unplug the screw terminal. This
allows you to leave the cable and cover at the installation site.
