TJWENHAO TWH-200W User Manual

Handheld Optical Multimeter

1．Overview

Handheld Optical multimeter is for the installation, operation and maintenance

of a fiber optic network designed accurate, durable and portable instrumentation. A

compact shape, automatic shutdown feature, wide range of optical power

measurement, accurate measurement accuracy, and user self-calibration function and

general interface design, while the linear index (mW) and nonlinear index (dBm)

display on the same screen.

Stable optical handheld multimeter can be customized to provide 1 to 4

wavelength stability of the output, not only can provide 650nm visible red light, single-mode fiber can

be measured to provide dual-wavelength 1310nm and 1550nm laser output, or provide 850/1300 /

1310/1550nm four wavelength laser output, fiber-optic project is the ideal test instrument.

2．Features

Self calibration by user himself

Rechargeable lithium battery used to reduce user costs

Linear (mW) and nonlinear index (dBm) display on the same screen

Can set the automatic shut down function

High stability multi-wavelength single-(multi) mode laser output, CW mode or modulated mode

Color LCD display

Data can be uploaded to PC
