neuberger: RPM375; Röhrenmessplatz

Does somebody have an idea does this apparatus can be used in vertical position, or it is can be used only horizontal. On the instruments there is rectangular sign which means, I think , horizontal usageThanks, sincerely, Perica.

Hello Perica,

in my opinion you can use the teser in vertical position as well.

Only when using the instrument in the prescribed operating position, errors remain within the limits set by the specified class.

You can test this. Adjust 4 Volts to the heater instrument and watch what the pointer is doing when you turn the tester upright.

Thank You Herr Reiner, I tried and there is no significant diference. Scale pointer correction was necessary with buttons on the instruments (for mA meter even that isn't necessary). What I mean does instruments can be somehow damaged if I use apparatus in vertical position. Does this also maters for RPM370 too, because I want to replace 375 with it(I more like round instruments).

Thanks again, Sincerely, Perica.
