  • Page 12: Calibration

    Chapter 1 General Information Calibration The Site Master is a field portable unit operating in the rigors of the test environment. An Open-Short-Load (OSL) or Open-Short-Load-Through (OSLT) calibration should be per- formed prior to making a measurement in the field. A built-in temperature sensor in the Site Master advises the user, via an icon located on the right side of the LCD screen, that the in- ternal temperature has exceeded a safety window, and the user is advised to perform an- other OSL or OSLT calibration in order to maintain the integrity of the measurement.
