Error Code: Type: Segment:
03PB Warning
 

Description:

Emission current (Ie) out of tolerance: $ 10 % (Ie >5 mA,exp.time % 44 ms) or $ 3 %(Ie >5 mA, exp. time >44 ms)
 
Possible Causes / Advice:

Connect an oscilloscope at EZ119 X7 large focus or X5 small focus and monitor the filament current behavior. Set kV-mA-ms technique with 50% of the max mA value at any kV value with an exposure time of 50ms. Any deviation between mA_set and mA_measured will cause a reaction in the filament current. If mA_measured is lower compared to mA_set the filament current will rise (up to filament max), if mA_measured is higher compared to mA_set the filament current will drop down to min 0.5A.

Check the mA measuring circuit in standby against oscilloscope screenshotma_pulse.pcx.

If warnings appear during normal work and if the tube has not been adapted for long time carry out the Tube Adaptation Procedure.
