FEDERAL COMMUNICATIONS COMMISSION AND INDUSTRY CANADA RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio-frequency energy, and if not installed and used properly, that is, in strict accordance with the manufacturer's instructions, may cause interference to radio communication. It has been tested and found to comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own expense will be required to take whatever measures may be necessary to correct the interference.

Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in the Radio Interference Regulation of Industry Canada.

WARNING: Never look directly into optical outputs or a fiber while the equipment is on. Invisible and visible laser beams may damage your eyes.

Do not short-circuit the AC adapter/charger terminal and the batteries. Excessive electrical current may cause personal injury due to fumes, electric shock, or equipment damage.

Connect the AC power cord to the equipment and wall socket properly. When you insert the AC plug, make sure there is no dust or dirt on the terminals and both plugs are fully seated.

WARNING: If the AC plug is not connected properly, fuming, electric shock, or equipment damage might occur and may result in personal injury.

Do not operate the equipment near hot objects, in hot environments, in dusty/humid atmospheres, or when condensation is present on the equipment. This may cause electric shock, product malfunction, or poor performance.

Status Icon Description

Full Battery at 100% capacity

2 Bars Battery at 50.75% capacity

1 Bar Battery at 25-50% capacity

Empty Battery at 0-25% capacity

The battery icon flashes when the power is almost depleted. Connect the AC adapter to the power meter to recharge the battery.

NOTES: To replace the batteries, use a screwdriver to remove the battery plate on the back of the power meter.

The AC indicator is not displayed when power is supplied by battery.

To eliminate the possibility of acid leakage, remove the battery if you won't use the power meter for an extended time.

3.2 AC Operation

If you will use the power meter at one location, for example, in a laboratory or test department, you can use the AC adapter to power it instead of batteries. Plug the AC adapter's output cable into the DC input jack on the bottom of the power meter. When the AC adapter is plugged in, the AC indicator on the LCD will be displayed. See Figure 3-3.

NOTES: Power is supplied by the AC adapter even if a battery is installed. The battery indicator does not display on the screen when AC adapter is plugged in.

Make sure that the AC adapter's operating voltage is within the range of the local AC voltage. For example, input: AC 100–240 V, 50–60 Hz.

Press the key for about two seconds to deactivate the auto-off function and the indicator will disappear on the LCD. The power meter powers off if the battery capacity is too low to support operation.

4.3 Setting the Wavelength

Press the key repeatedly until the desired wavelength displays. Select from six possible wavelengths: 850, 1300, 1310, 1490, 1550, and 1625 ~nm . The default wavelength is 1550 ~nm .

The power meter defaults to the wavelength that you set in the last test.

When used with an optical laser source, the wavelength will shift according to the laser source's output wavelength. Press and hold the key to activate auto-wavelength recognition.

4.11 Connecting to the Optical Laser Source

When connected to the dual-wavelength laser source (FOLS-SM-200 or FOLS-MM-200), the Optical Power Meter (FOPM-210) accurately measures loss at distances up to 250 kilometers at 1550 nm. On-the-spot measurement will differ with the working wavelength, fiber attenuation, and the testing environment.

5. Maintenance

Disconnect the AC adapter/charger and replace the protective dust cap once you finish using it.

Clean the connector and the instrument when they get dirty from use. We recommend using optical cleaning pads and anhydrous alcohol. Be careful not to get liquid inside the instrument.

For measurement accuracy, calibrate the power meter once a year.
