HIOKI MR8902 VOLTAGE/TEMP UNIT

No. of channels: 15, for voltage/temperature measurement (selectable for each channels)

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)

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.
