Hioki MR8902 VOLTAGE/TEMP UNIT

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

Data refresh rate
