a Unless otherwise stated, these specifications apply fort the reference condition: ambient temperature 23±3 °C, relative air humidity 40 % to 60 %, continuous wave signal (CW), RMS detection (frequency range: 30 Hz to 400 kHz) b Depends on type; see Ordering Information c Detection: Automatic according to selected standard d Includes flatness, isotropy, absolute and linearity variations (frequency range: 1 Hz to 400 kHz or 10 Hz to 400 kHz). The uncertainty increases at the frequency band limits (10 Hz, 30 Hz, 400 kHz) to ±1 dB based on the nominal frequency response. e For Frequency Range 1 Hz to 400 kHz and 10 Hz to 400 kHz only.
