Strain Unit (8860/61)
8960 STRAIN UNIT (Accuracy at 23 5 C/73 9 F, 35 - 80 % rh after 1 hour of warm-up time
and auto-balance; accuracy guaranteed for 1 year)
Measurement functions Number of channels: 2, for distortion measurement (electronic auto-balancing, balance adjustment range within 10000 )
Input connectors
Via adapter cable, TAJIMI PRC03-12A10-7M10.5, Max. rated voltage to earth:
33 Vrms or 70 V DC (with input isolated from the unit, the maximum voltage that can be
applied between input channel and chassis and between input channels without damage)
Suitable
transducer
Strain gauge converter, bridge impedance: 120 to 1 k (bridge voltage 2 V),
350 to 1 k (bridge voltage 5 V, 10 V), bridge voltage 2, 5, 10 0.05 V
Measurement
range
20 - 1000 /division, 6 ranges, full scale: 20 divisions, lowpass
filter: 5/10/100/1 kHz
Anti-aliasing filter Integrated filter for suppressing aliasing distortion caused by FFT
processing (automatic cutoff frequency setting/OFF)
