Chapter 3:Operation
3. Operation
3.1 Battery Indicator
A battery indicator on the screen shows the remaining charge. See Figures 3-1
and 3-2. Table 3-1 describes the LED status.
Figure 3-1. Battery indicator full.
Figure 3-2. Battery indicator empty.
Table 3-1. Battery indicator status.
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. Contact Black Box Technical Support for a
replacement battery.
The AC indicator is not displayed when power is supplied by battery.

Page 11
Chapter 3:Operation
NOTES (continued): 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.
Figure 3-3. AC adapter indicator.
NOTES: Power is supplied by the AC adapter even if the battery is installed. The
battery indicator does not display on the screen when the 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.

4.2 Turning the Optical Power Meter On and Off
1. Press the “ON/OFF” key briefly. The power meter powers on, and backlighting
switches on and sounds a short buzzer.
If the power meter does not turn on, check the battery charge and make sure
the battery is connected properly. If the battery fails, contact Black Box Technical
Support at 724-746-5500.
Figure 4-4. Powering on the power meter.
2. Press the "ON/OFF" key briefly again. The instrument powers off, and back
lighting switches off and the buzzer sounds briefly. When the battery capacity
indicator flashes on the LCD, recharge the battery or install a new battery.
Figure 4-5. Powering off the power meter.
3. Turn on/off the auto-off function. The power meter powers off automatically if
you do not press a key within 10 minutes. Press the ON/OFF key for about 2
seconds to deactivate the auto-off function and the indicator will disappear
from the LCD. The power meter powers off if the battery capacity is too low to
support operation.

4.4 Setting and Checking the Reference Level
1. Setting the reference level: Press and hold the "REF" key for more than two
seconds to store the presently measured value as the new reference level for
the current wavelength. Once you set the new reference level, the LCD displays
0.00 dB, the buzzer sounds, and the power meter switches to dB measurement
mode.

4.8 Connecting to the Optical Laser Source
When connected to the dual-wavelength laser source (FOLS-SM-100 or FOLSMM-100), the FOPM-100 accurately measures the loss at distances up to than
250 kilometers at 1550 nm. On-the-spot measurements will differ with the testing
wavelength, fiber attenuation, and testing environment.
