Influence quantities and variations
for 12S ... 16S, 14A
1) With temperature: Error data is per 10 K change in temperature.
With frequency: Error data is valid from a display of 300 digits.
2) With zero setting
3) With unknown waveform (crest factor CF > 2), the measurement must be made with manual range selection.
4) Except for sinusoidal waveform
5) From the time the symbol „ ” appears.
Influence quantities and variations
