Chapter 2: Overview
The WP-TEST-FIBER-400 Optical Power Meter is a newly designed fiber optic tester intended
for the installation, engineering acceptance, and maintenance of fibernetworks.
Compared with other power meters, the WP-TEST-FIBER-400 Power Meter has more functions,
including automatic wavelength identification, auto wavelength switching, intelligent backlight, and
data saving via USB port.
Combined with its matched handheld optical light source, it offers a quick and accurate testing
solution on both single mode and multimode fibers.
WaveID:Autowavelengthidentification&switching

Push the clip fastener on the battery compartment cover down. Remove the battery compartment
cover and remove all three batteries, making a note of their positive and negative connector
orientation. The negative battery connector should be against the spring. Insert 3 new 1.5VV AA
batteries. Refit the battery compartment cover. The clip fastener should click shut.
Note :Insert the batteries with their positive and negative connectors correctly aligned.
6.1.2 Power Supply Unit
When the battery is empty, the power supply unit can be used. At the top left of the screen,
( 6-3) will be displayed. When the battery is in the power meter and still charged, the tester
will default to the AC power supply.

6.6 Frequency Detection
Light source and power meter will both operate units at 270Hz in almost all testing conditions.
Note:Frequency ID and wave ID cannot be operated at the same time.
To avoid risk of serious eye damage, do not look into the optical port of laser source at any time.
6.7 Power off
Automatic power off: When auto-off function is activated, the unit will turn itself off automatically after
10minutes idle, whether on battery or AC power
Manual power off: Under any operation mode, hold down for a few seconds to turn the unit off.
Note: The unit will store the last calibration wavelength andbacklight control mode automatically.
This will be the default setting when the unit is next turned on.
