TPMHC0203EAWARNING ~ High Voltage ~The product is operated at high voltage potential. Further, the metal housing of the product isconndcted to the photocathode (potential) so that it becomes a high voltage potential when theproduct is operated at a negatibe high boltage (anode grounded).
Accordingly, extreme safety care must be taken for the electrical shock hazard to the operator orthe damage to the other instruments.
