1. Analog output

The MS-80 and MS-80U have an analog output for irradiance and detector temperature.

 Use a measuring device with an input impedance of 100MΩ or more. Low input

impedance may cause underestimation of the output voltage measured.

 Be sure to connect the cable shield to the frame ground of the measurement device,

otherwise noises may occur.

A. MS-80 (from S/N: S19046151, temperature sensor 3W Pt100 class A). Connect the 5 wires with corresponding

color to the input terminals of the voltmeter or data logger (figure 5-5).

[*] Always connect the shield cable to prevent signal noise.

[**] See the Appendix A-8 resistance to temperature conversion table [PT-100].

B. MS-80 (Till S/N: S19046150, temperature sensor type NTC 10kΩ). Connect the 4 wires with corresponding

color to the input terminal sof the voltmeter or data logger (figure 5-6).

[*] Always connect the shield cable to prevent signal noise.

[**] See the Appendix A-7 resistor to temperature conversion table. [NTC 10k Ω].
