2ch, Distortion measurement for strain gauge converter.
This UNIT is equipped with circuits for two independently usable input channels. Simply slot the 8939 into the MEMORY HiCORDER for use.
| 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 |
