MR8902 Voltage/Temperature Unit
Measure minute voltage or temperature waveform by 16 bit resolution, isolated input
Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
| Functions | No. of channels: 15, for voltage/temperature measurement (selectable for each channels) |
|---|---|
| Input connectors | Voltage/thermocouple input: push button terminal Recommended wire diameter: single-wire φ 0.32 mm to φ 0.65 mm, stranded wire 0.08 to 0.32 mm2 (conductor wire diameter min. φ 0.12 mm), AWG 28 to 22 Input resistance: 1 MΩ Max. rated voltage to earth: 100 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) |
| Voltage measurement ranges | 500 μV to 5 V/div, 9 ranges, full scale: 20 division * The AC instantaneous voltage waveform cannot be measured due to the slow sampling speed. Resolution: 1/1000 of measurement range (using 16-bit A/D converter) Accuracy: ±0.1 % f.s. (with digital filter ON, Zero position accuracy included) |
| Temperature measurement range | Reference junction compensation: Internal/ External (selectable) Thermocouple broken-wire detection: ON/OFF (selection applies to entire unit) Thermocouple type: K, J, E, T, N, R, S, B, WRe5-26 * For thermocouple measurement ranges, resolution, and accuracy, refer to the specifications table below |
| Digital filter | 50 Hz, 60 Hz, or OFF |
