23-1. Analog Input Section
Two-system inputs
(Standard: CH1=strain gauge input, CH2=voltage input)
(Optionally, changeable as follows:)
Strain gauge input
Sensor excitation voltage: Switching between 10V and 2.5V DC (by setting)
Output current: 120mA or less (total of two inputs)
Four-wire type (When only one input is used, up to
four 350Ω strain gauge type sensors can be connected
to the F395 in parallel.)
Signal input range: -3.0mV/V ~ +3.0mV/V
Zero/gain adjustment: By digital operation.
Equivalent input calibration range:
-3.0mV/V ~ -0.5mV/V
+0.5mV/V ~ +3.0mV/V
Equivalent input calibration range error:
Within 0.2% F.S.
Accuracy: Non-linearity: Within 0.02% F.S. ± 1 digit
(at 3.0mV/V input).
Zero drift: Within 0.5μV/ ℃ RTI
(input-converted value).
Gain drift: Within 0.01%/ ℃ .
Analog filter: Selectable from 10, 50, 200, and 600Hz
A/D converter: Speed: 4000 times/sec. (max.) when one input is used.
2000 times/sec. (max., X-axis measurement)
when two inputs are used.
Changeable to
100, 200, 500, 1000, 2000 times/sec.
according to the input waveform.
Resolution:
Approx. 1/30000 relative to 3.0mV/V
