Strain amplifier This UNIT is equipped with circuits for two independently usable input channels. Simply slot the 8939 into the MEMORY HiCORDER for use. Basic Specifications

• Input Number of channels: 2, Connector: Adapter cable connector * Input isolated from output, inter-channel isolation
• Converter connector Via adapter cable, TAJIMI PRC03-32A10-7F10.5
• Suitable converter Strain gage converter, bridge impedance: 120-ohm to 1 k-ohm, gage factor 2.00, bridge voltage 2 ±0.05 V
• Measurement range 20 µe to 1000 µe/division, 6 settings, the measurement resolution is 1/80 of range * When attached to recorder where full-scale (f.s.) = 20 divisions
• 50 µe to 2000 µe/division, 6 settings, the measurement resolution is 1/160 of range * When attached to recorder where full-scale (f.s.) = 10 divisions
• Low-pass filter: 10/30/300 Hz/3 kHz, OFF
• Maximum sampling rate 1 MS/s (simultaneous sampling for 2 channels)
• Accuracy (after auto-balancing) DC amplitude: ±(0.5 %f.s. +2 µe) Zero-position: ±0.5 %f.s.
• Balancing Electronic auto-balancing, max. adjustment range ±10000 µe
• Zero-position -50 % to 150 %, 1 % step * With auto-balancing
• Frequency characteristics DC to 20 kHz +1/-3 dB
• Max. allowable input 10 V (DC + AC peak) (upper voltage which when applied to between input pins does not damage them)
• Max. rated voltage to earth 30 V rms or 60 V DC (upper voltage which when applied to input channel casing or between input channels does not damage them)
• Accessories Conversion cable (2), PRC03-12A10-7M 10.5 (2)
