Hioki Memory HiLoggers are high-speed data loggers for recording multiple chanels of voltage, temperature, pulse or rotation signals, providing complete isolation between channels and strong noise resistance . The LR8431 logs data at 10ms speeds across 10 channels simultaneously, and features a bright color LCD for crystal clear waveform displays.
| Number of channels | Analog: 10 isolated channels using scanning input method (M3 mm dia. screw terminal block) Pulse: 4 channels (All pulse inputs share common ground with the main unit) |
|---|---|
| Measurement parameters | Voltage : ±100 mV to ±60 V, 1-5V f.s. 6 ranges, Max. resolution 5µV Temperature (thermocouples) : -200 ˚C to 1800 ˚C (depend on the sensor), 1 range (K, J, E, T, N, R, S, B), Max. resolution 0.1 ˚C Temperature (Pt 100 sensor) : cannot use Humidity : cannot use Totalized pulses : 0 to 1000M pulse, 1 range (No-voltage ‘a’ contact, open collector or voltage input), Max. resolution 1 pulse Rotation count : 0 to 5000/n (r/s) f.s. 1 range (No-voltage ‘a’ contact, open collector or voltage input), Resolution 1/n (r/s) Note: n = pulses per rotation (1 to 1,000) |
| Max. allowable input | DC 60 V (Analog input), DC -5 V to 10 V (Pulse input) |
| Max. rated voltage to earth | AC 30 Vrms, DC 60 V (Upper limit voltage that does not cause damage when applied between input channel and chassis, and between each input channels) |
| Recording intervals | 10 ms to 1 hour, 19 selections (All input channels are scanned within each recording interval.) |
| Selectable filters | 50 Hz, 60 Hz, or OFF (digital filtering of high frequencies on analog channels) |
