Description
Hioki MR8905 Analog Unit
| Functions | No. of channels: 2, switchable between instantaneous value and AC RMS value |
|---|---|
| Input connectors | Banana connector (input impedance 4 MΩ, input capacitance less than 1 pF)Max. rated voltage to earth: CAT II 1000 V AC & DC, CAT III 600 V AC & DC (with input isolated from the main unit, the max. voltage that can be applied between input channel and chassis and between input channels without damage) |
| Measurement range | 500 mV to 50 V/div, 7 ranges, full scale: 20 div*The maximum displayable AC voltage is 700 Vrms when using 1/2 compression of the vertical axis. |
| Low-pass filter | 5/50/500/5 kHz, OFF |
| Resolution | 1/1250 of measurement range (using 16-bit A/D converter) |
| Highest sampling rate | 500 kS/s (simultaneous sampling across 2 channels) |
| Accuracy | ±0.5% f.s. (with 5 Hz filter ON) |
| RMS measurement | RMS accuracy: ±1.5% f.s. (30 Hz up to but not including 1 kHz, sine wave input) or ±3% f.s. (1 kHz up to 10 kHz, sine wave input)Response time: 300 ms (filter off, rising from 0% to 90% f.s.) or 600 ms (filter off, falling from 100% to 10% f.s.)Crest factor 2 |
| Frequency characteristics | DC to 100 kHz -3 dB |
| Input coupling | DC/AC-RMS/GND |
| Max. allowable input | 1000 V DC, 700 V AC (the max. voltage that can be applied across input pins without damage) |
| Dimensions and mass | 119.5 mm (4.70 in)W × 18.8 mm (0.74 in)H × 151.5mm (5.96 in)D, 185 g (6.5 oz) |
