Anritsu FAQs

Calibration is absolutely necessary for good measurements. When you save a setup after calibration, assuming that you are using the "B" series Site Master, the calibration data is stored with the setup. As long as the temperature icon does not appear on the display you are in good shape. Now, if you listen to the design engineers, they are perfectly correct when they say that you may turn the Site Master off and then at a later day turn the unit back on and recall the saved setup with calibration. True statement. However, from a practical point of view, there is a temperature sensor mounted internally, which monitors the temperature of the PC Board. It is always good practice that when you turn the Site Master back on, that you allow it to warm up for about five minutes. Then recall the saved setup, re-calibrate and save it again over the same location. This eliminates the possibility that the temperature window was close to a limit. Especially in those areas where the outside temperature may change many degrees over the period of a day. Also, it is good practice to re-calibrate and save, when you have time to kill, such as while working up a tower. This may save you from suddenly seeing the temperature icon appearing as you make a measurement. Press "SYS" and "STATUS" to see the internal temperature range.
