F.W. Bell 4090 Operating Instructions

III. Specifications

Dynamic Range: 0.1 mG to 1999 mG, RMS,
autoranging over four decades (20,000:1). 199.9 mG
full-scale with 0.1 mG resolution in high-sensitivity
mode. 1999 mG full-scale with 1 mG resolution in
low-sensitivity mode.
Accuracy: 1% ±1 digit typical. The instrument is true
RMS responding, calibrated to a sine wave at 55 Hz.
DC Output (OPT D): 10 mV/mG; 2 volts FS at
200mG. Output impedance is 4kΩ.
Directionality: ± 1% (typical) for all measurement
angles.
Frequency Response: Essentially flat (± 10%)
between 40-400 Hz, with cutoff frequencies (-3 dB) of
30/600 Hz. Accuracy is better than ± 5% between 40-
rd
200 Hz for accurate measurement of the 3 and 5
Hz harmonic. OPTION F20 extends the -3 dB
frequencies to 20/2000 Hz.
Sensor Type: 3 x 1700 turns #38 Cu; 0.29" dia. air
core.
Environmental: Temperature Range: -10°C to +50°C
operating and -20°C to +85°C storage. Relative
Humidity: 90% at +40°C operating and 95% up to
+60°C storage.
Battery Life/Power Source: 50 hours, typical use (to
5.1V min.) using standard 9V alkaline battery
(Duracell MN1604/Eveready 522/or equivalent).
Size/Weight: Case dimensions are 5.9"H X 3.2"W x
1.2"D (OPT X01 add 0.4" to H). Weight
approximately 7 oz. (200g).
Analog Output (OPT A): Z-Axis waveform
only. 5 mV/mG; 1 volt FS at 200 mG. Output
impedance is 4 kΩ.
