[1] Below 5 % of range, add 20 counts.
[2] Specification increases linearly from -2 % at 200 Hz to -6 % at 440 Hz. Range is limited to 440 Hz.
[3] dBm (600 Ω) is specified by adding +2.2 dB to the dBV range values.
[4] 289 only.
[5] 500 mV range specification between 64.000 kHz and 67.000 kHz is +(0.0 % to -5 % of reading); 50 mV range specification between 64.000 kHz and
67.000 kHz is +(0.0 % to -6 % of reading ±40 counts). Valid from -20 °C to +55 °C.
[6] Add 2 % above 75 kHz.
