Section #5 - Caring for the TruAngle
Operating Temperature
The TruAngle components are rated for a temperature range of -22
to 122
F (-30
to 50
C).
Do not expose the instrument to temperatures outside this range.
Moisture and Dust Protection
The Angle Encoder is sealed to provide protection from normally expected field conditions. It is protected
from dust and water, and features temporary submersion resistance.
If water leakage is suspected:
1. Power OFF the Angle Encoder.
2. Remove the batteries.
3. Air-dry the encoder at room temperature with the battery compartment open.
Shock Protection
The TruAngle is a precision instrument and should be handled with care. It will withstand a reasonable
drop shock. If the encoder is subjected to a severe mechanical shock, you should power on the instrument
and index the encoder
.
Cleaning and Storage
Clean the TruAngle after each use. Before returning it to its case, check for the following items:
•
Excess moisture.
Towel off excess moisture, and air-dry the instrument at room
temperature with the battery compartment open and the batteries removed.
•
Exterior dirt.
Wipe exterior surfaces clean. Use isopropanol to remove dirt and
fingerprints from the exterior surfaces.
•
Batteries.
If you do not expect to use the TruAngle again soon, remove the
batteries before storing it.
Display Screen
It is a good idea to periodically check the display screen to make certain that all display segments are
working properly. For more information, see Extend the Display Segment Test
