  PROBE POLARIZATION Connect the probe to the instrument. Turn the instrument ON by pressing The probe is under polarization with a fixed voltage of On/Off. approximately 800 mV. Probe polarization is essential for stable measurements with the At start-up the display will show same recurring degree of accuracy.
