The IDEAL FiberMASTER 33-931 Fiber Optic Testing Kit User Manual explains operation, calibration, safety, and specifications for measuring optical power and…
The FiberMASTER 33-931 kit from IDEAL provides a power meter and laser light source for absolute power measurement and loss calculation across multiple wavelengths (850, 1300, 1310, 1490, 1550 nm). It includes universal adapters, SC/ST/FC jumpers, a calibration coupler, and a rugged carrying pouch for field use.
The manual covers safety warnings, two measurement modes (absolute power and relative loss), step‑by‑step calibration, operation of the power meter and light source, and detailed technical specifications. It also includes maintenance, warranty, and service information.

Connect the light source to the power meter with reference jumpers, press the ‘dB/Cal’ button to store the current power level (display shows 0.00 dB), then remove the coupler and measure the loss of the test cable.
The device operates in absolute power measurement mode (displaying dBm or µW) and relative power measurement mode (displaying loss in dB).
The power meter runs for approximately 360 hours on three AAA alkaline batteries.
