Maintenance

The AV760 is a precision instrument and must be

maintained to ensure proper functions. If the AV760

sensors get dirty and no longer read correctly, the

Sensor Housing can be removed to enable easy

cleaning of the sensors.

1. Remove the tting, o-ring, and the oil catch lter

from the sensor housing.

WARNING: Do NOT remove the protective screen

covering the sensor.

2. Apply Isopropyl Alcohol (70% or higher) to the

sensor ports and flush the sensor ports for 5

minutes (page 9).

WARNING: Do NOT touch the sensors or insert

any objects into the sensor ports. Doing so may

permanently damage the sensors.

3. Drain the uid out of the sensor and apply a short

low pressure puff of air, no higher than 50psi,

directed at the sensor housing. Let dry for at least

1 hour.

4. Replace the o-ring and lubricate with vacuum oil.

5. Check the oil catch filter for oil by blotting it on

a clean tissue or paper towel. If any oil remnants

appear, discard the oil catch lter and replace with

a new one.
