Accuracy Table
• Crest factor: The crest factor is 3 up to 4000 counts and reduces
linearly to 2 at 6000 counts.
• Connection method: AC coupling
• Auto range movement threshold: 6,000 counts or more for upper range,
540 counts or less for lower range
*1: The accuracy is speci fi ed in 1% or more of the range, however, ±5
dgt. should be added to 5% or less of the range.
• Accuracy guarantee range for frequency: 40 Hz to 1 kHz (Measured values
outside the accuracy guarantee range for frequency are also displayed.)
The accuracy is not speci
fi ed for strain waveforms outside the range of
40 Hz to 1 kHz.
• For 100 Hz with the fi lter ON, ±1.5% rdg. is added to the accuracy
speci fi cation between 40 Hz and 100 Hz and the accuracy is not
speci fi ed in 100 Hz or more.
• For 500 Hz with the fi lter ON, ±0.5% rdg. is added to the accuracy
speci fi cation between 40 Hz and 500 Hz and the accuracy is not
speci fi ed in 500 Hz or more.
