Technical Specifications
This chapter provides technical specifications on each of the system units.
11.1
Position Sensor
The system requires a warm-up time from storage temperature to operating temperature equivalent
to 10 minutes plus one minute for every 1°C of difference between storage temperature and
operating temperature. (If the temperature difference is within 5°C, the warm-up time will be 10
minutes.)
For example, if the system is stored at -10°C and moved to a location at +30°C, the warm-up time
will be 10 minutes, plus an additional 40 minutes to account for the difference in temperature.
Do not transport or store the Position Sensor outside the recommended storage temperature range, as this may
cause the system to go out of calibration. Reliance on data provided by an out of calibration Position Sensor may
Warning!
lead to inaccurate conclusions and may cause personal injury. A calibration procedure must be performed
before using the Position Sensor after it has been transported or stored outside the recommended storage
temperature range.
