The Micro OWL 2 is a high accuracy, high resolution, microprocessor controlled, optical power meter. The meter has a 75dB dynamic range making it ideal for both single-mode and multimode fiber testing. It has an attractive handheld case with a backlit, graphic, liquid crystal display, and 18-key keypad for easy data entry. It is offered with a 2.5mm universal fiber connector, with a 1.25mm universal cap for LC, MU, and other 1.25mm SFF connectors. It will operate for over 100 hours on a standard 9v battery and has built in auto shutdown.
The Micro OWL 2 includes OWL’s user-friendly Link Wizard that helps you easily calculate the allowable loss for the fiber runs that you will be measuring. The meter stores physical fiber information for up to four link configurations which includes link name, date, fiber type, fiber length, connectors, splices, temperature, and calculated or entered reference power values for three wavelengths. In addition the meter will store up to 1000 measured data points with labels.
The auto-wavelength switching feature of the Micro OWL 2 allows for convenient dual-wavelength data storage, which helps eliminate human error and cuts down testing time nearly in half. This convenient feature is available when used with OWL WaveSource series fiber optic light sources.
The stored information can be selectively viewed, edited (measured again), printed, or deleted. The meter will print formatted reports of selected stored data directly using the built in USB port, or all of the stored data can be downloaded to a computer spreadsheet or our free OWL Reporter software to produce formatted certification reports. A charger port is also included for re-chargeable 9-volt batteries. Optionally, a Visual Fault Locator can be installed in the place of the battery charging port for visual fiber identification or troubleshooting faults in the near-end of a fiber link.

General Features
- 2.5mm Universal Connector Port - accepts many popular 2.5mm ferrule connectors, including ST, SC, and FC. Also included is a 1.25mm universal adapter cap (for connection to LC, MU, and other SFF connectors).
- USB Download Port - downloads stored data to a PC using the supplied USB download cable.
- Charger Port / VFL Port and Indicator LED - Allows for charging of re-chargable 9-volt batteries, as well as wall power operation (9VDC transformer and 9-volt re-chargeable battery not included). DO NOT USE BATTERY CHARGING PORT WITH NON- RECHARGEABLE BATTERIES, AS THIS COULD POTENTIALLY CAUSE HARM TO THE UNIT AND/OR THE USER.
- LCD Display - shows optical power/loss levels, power units, temperature, battery life, wavelength, and circuit ID information.
- Function keys activate certain menu options shown at the bottom of the Micro OWL 2 LCD display
- Enables user to enter alpha-numeric data, as well as activate certain menu options
- Allows the user to enter the MAIN MENU
- While in the menu system, reverts the user back one menu level; during data entry, enters the data input and sends the user to the next screen
- Toggles the backlight between on and off
- Turns the unit ON and OFF
General Features - LCD DISPLAY
The screen below shows information when power readings are being taken. We will refer to this screen throughout this manual as IMMEDIATE MODE.

- POWER READING - shows the amount of optical power being received by the photodetector based upon the type of power units currently being displayed. “UNDER” means there is no measurable optical power and “OVER” means the detector is “blinded” by too much optical power
- POWER UNITS - shows the power units which are currently being displayed dBm - optical power in decibels relative to a milliwatt of optical energy dB - optical power in decibels relative to a previously set optical reference, also known as optical loss uW - optical power in micro- (uW) or milli-watts (mW)
- TONE DETECTION - shows ‘Hz’ if a modulated signal is being detected by the meter
- TEMPERATURE - shows current temperature in degrees (selectable Fahrenheit or Celcius)
- BATTERY LIFE - shows the percentage amount of remaining battery life; will flash when battery is low
- LINK NAME - shows the name of the currently loaded fiber link (CERTIFICATION METER mode only)
- FIBER RUN - shows the current fiber information (CERTIFICATION METER mode only)FBR: - user-configurable descriptive fiber name 123 - auto-incrementing fiber number (from 1 to 999)
- FUNCTION OPTIONS MENU - functions corresponding to the function keys on the keypad; the options on this menu will change according to the current function
- POWER METER WAVELENGTH - shows the currently selected wavelength (see the specifications in the appendix at the end of this manual for a list of wavelengths); will also alternate between wavelength and ‘AUTO’ when set to automatic wavelength detection
