The soft Cal Cup insert enables calibration of the basic sensors when
the RDO sensor is installed. It contains

UNPACK THE RDO DIRECT CONNECT SENSOR
The RDO direct connect sensor ships in a box as shown below:
INSTALLING THE RDO SENSOR CAP
1. Remove the red protective dust cap from the sensor and save it for later use.
Protective dust cap Sensor cap
2. Use the supplied lens wipe to clean the lens of the sensor, if necessary.
3. Remove the RDO sensor cap from its shipping sleeve.
4. Align the arrow on the cap with the index mark on the sensor and
firmly press the cap onto the sensor, without twisting, until it seals
over the probe body.
Keep the cap in its sealed packaging until ready to install it.
Make sure that the o-ring is not pinched or rolled inside the cap.
The cap’s lifetime is 1 year after the first reading has been
taken. Install by the date printed on the packaging.
INSTALLING THE RDO SENSOR
1. If necessary, install batteries in the TROLL 9500 instrument.
Please exercise great care in handling, installing, and
shipping lithium batteries. Refer to the instructions, cautions
and MSDS packed with the batteries.
2. Remove the standard restrictor or Cal Cup from the TROLL 9500
instrument (if attached). This allows access to the sensor block.
3. Determine the installation port(s) for the RDO sensor. For the
cable connect, choose port 1 or 3. For the direct connect, you
must choose ports 2 and 3 (with the connector pins in port 3).

4. Use the Sensor Removal tool to remove the plug or existing sensor
from the appropriate port. Port 1 is normally easier to access.
TIP: If installing in port 3, you may wish to remove the port 2
sensor temporarily (if installed).
5. Attach the RDO Sensor to the TROLL 9500:
a. Remove the soft cap from the connector end of the direct
connect RDO sensor. Attach the direct connect sensor and
any other remaining sensors (in ports 1 and 4), if applicable.
Proceed to step 6.
b. For the cable connect sensor, insert the front end of the TROLL
9500 instrument through the large hole in the adapter, alongside
the RDO sensor.
