Switching on the instrument
This key is used to switch the instrument on or off. When the
instrument is switched on a self-test is run which checks the
microprocessor. The test lasts about 6 seconds. The
following text is displayed when the test is in progress:
SPM-TEST
The instrument is then automatically calibrated. Calibration
involves all subassemblies and lasts about 15 s. The
following text is displayed when calibration is in progress:
CAL
When the "CAL" symbol disappears you can make
measurements. The current setting is the same as the
setting when the instrument was last switched off.
You can also call up the calibration routine during
measurements.
It is a good idea to calibrate the instrument if changes in
ambient temperatureoccur. Calibration every 30 minutes
ensures that the full accuracy of the set is utilized.
This procedure does not affect the instrument settings.
