Battery Charging Port - If rechargeable 9-volt batteries are used in the PM200, the
battery charging port is used to re-charge them when used with an approved wall
transformer. NOTE: DO NOT USE BATTERYCHARGING PORT WITH NON-
RECHARGEABLEBATTERIES. THERE IS THE POTENTIAL FOREXPLOSION
AND DAMAGE MAY OCCUR TO THE UNITAND/OR THE USER.
Download Port - The download port is used to download stored data into a PC via
the supplied serial cable.
Detector Port - The detector port is a fixed 2.5mm universal port, and connects to
ST, SC, or FC connectors equally well without any loss of accuracy. There is no
need to change or maintain expensive adapter caps.
Tone Mode - When ‘Hz’ is visible on the display, the PM200 is checking for the
presence of a modulated optical signal. These modulated signals are used to
automatically switch wavelengths when they are sent by an OWL light source with
modulation capability.
Power Reading - The power reading displays the level of optical power being
received by the photo detector, and is displayed in either dBm, dB, milliwatts, or
microwatts.
Battery Indicator - The battery indicator shows the amount of life is remaining in the
battery. Also, when the battery recharger is in use, the bars in the battery icon are
animated to show that the recharger is active.
Data Indicator - This icon shows whether there is data stored in the PM200.
Units Indicator - The units indicator shows which units are being currently displayed.
Units are shown in either dBm, dB, uW, or mW.
Wavelength Indicator - The wavelength indicator shows the currently selected
wavelength in nanometers (nm).

10. SAVE / DOWNLOAD button - To store a data point, press this button. Hold the
button to down load data points in comma-delimited format. This button can also be
used to erase all stored data if it is held while the meter is being powered ON.
11. ON / OFF / Backlight button - When the unit is off, press this button to power on.
When the unit is on, press this button to toggle the backlight on and off. When the
unit is on, hold this button to power off.

λ
/ AUTO button - Press this button to change wavelengths. Hold this button to set
the meter in AUTO mode. AUTO mode scans incoming power for modulated optical
signals, and switches wave lengths automatically when a corresponding modulated
signal is received (for use with WaveSource light sources only.)
13. UNITS / ZERO button - Press this button to change display units - either dBm, dB,
uW or mW. Holding this button will set a ZERO reference for the currently selected
wavelength.
