Warning!
● Never look directly into optical outputs or a fiber while the equipment is on. Invisible light can easily
cause injury to your eyes.
● Do not short-circuit the terminal of AC adapter / charger and the batteries. Excessive electrical
current may cause personal injury due to fumes, electric shock, heat or equipment damage.
● Connect the AC/DC power cordinto the wall socket properly. While inserting the AC plug, make sure
there is no dust, dirt, water or other contaminants on the terminals and that both prongs are fully
seated. Incomplete engagement may cause fuming, electric shock, fire or equipment damage, and
may result in personal injury.
● Do NOT operate the equipment near hot objects, in hot environments, in a dusty / humid atmosphere
or when condensation is present on the equipment. This may result in electric shock , product
malfunction or poor performance.

3.1 Unpacking the Device
Packing Material
We suggest that you keep the original packing material. Using the original packing material will adequetly
protect the device during transport to an authorized PRO service center for calibration or repair.
Checking for Damage from Shipping
After unpacking the device, immediately check for any damage from shipping. This is more likely if the
outer casing is clearly damaged. If there is damage, do not attempt to operate the device or to repair it
without authorization. Doing so can cause further damage the device and will void your warranty.
3.2 The Rechargeable Batteries
There is a battery indicator on the screen that displays the remaining charge. There are four modes the
indicator may show: FULL (3 black bars), MEDIUM (2 black bars), LOW (1 black bar) and “Discharged”.
Please note that when the remaining battery power is too low for the device to properly function, the
device will automatically turn off.
3. Preparing for Operation
3.3 AC/DC Adapter/Charger Operation
There is a DC input jack on the bottom side of the OLM-200 Series device casing into which the output
cable of the AC/DC adapter/charger is plugged. When the AC adapter is plugged in and the device is
turned off, a “Charging” indicator on the LCD will be displayed.
Note:
Make sure that the operating voltage is within the allowable range: Input: AC 100-240V (50-60HZ).
Warning:
The AC/DC adapter/charger must NOT be used
when powering the device with alkaline
batteries. Doing so will damage the batteries,
damage the device and void your warranty

4.2 USB Interface
You can use the USB interface to connect the device with a PC and upload the stored data. There is a
socket on the bottom side of the device next to the DC input jack. Use the supplied USB cable to connect
the device to the USB interface of a PC. When the USB cable is connected, the indicator on the LCD will
be displayed.
4.3 Turning the Device On and Off
Press the “ON/OFF” button briefly.
The device powers on and backlighting switches on. If the device fails to turn on, the first thing to check
is the battery condition and charge level. If in doubt, you can use alkaline batteries to test the device. If
the device still does not turn on while using alkaline batteries, the device is defective.
Press the “ON/OFF” button briefly again to turn the device off..
4.4 Activating the “Automatic Shutdown” Feature
The device powers off automatically. If the device fails to automatically shut down after 10 minutes,
press the “ON/OFF” button for about 2 seconds to power on the device with “Auto-Off” function
deactivated.
4.5 Turning On and Off the LCD Backlighting

5.1.2 Shifting the Measurement Devices of the Optical Power Meter
The power meter defaults to the device of “dBm”. Press the “Device” button to shift from “dB” to “mW”.
Note:
1) “dB” and “mW” are the units representing the absolute value of the tested power value. If the tested
power value is less than 1mW while set to “mW”, the device will be shifted to “uW” automatically.
2) “dB” is the relative value of testing power. Firstly, the user should set a reference value. Then,
the current value can be compared to the reference value. The formula is: “dB” value equals the
“reference value” minus the “the current power value in dBm”.

5.1.3 Setting Reference Value on Optical Power Meter
The reference value defaults to 0.00dBm when in Optical Power Meter mode. Push and hold the button
for over 2 seconds to set the current optical power value as the reference value. Quickly pressing and
releasing the button will display the current reference value. The device will return to a testing mode
after two seconds if no button is pushed. If a signal is detected, the device will shift to the REF editing
mode.
Note:
Push and hold for over 2 seconds to shift to "dB" mode automatically.
5.1.4 Loading and Storing the Optical Power Values
Push and hold “LOAD” for longer than 2 seconds to store the current values, including the wavelength,
values, modulation, modes and devices being tested. It will list and display the current record number
from “001” to “999” on the LCD.
Quickly press and release the “LOAD” button to display the stored data.
Press the “LOAD” button again to exit the “Data History” mode.

5.2.3 Setting the Reference Value to Default
Press the “Lambda” button to set the reference value in the current wavelength to “-5dBm”. Push and
hold to set all the reference values (in all wavelengths) to “-5dBm”.
Note:
Setting the reference value to “-5dBm” is for working with a “-5dBm” Light Source. When matched, the
loss of the circuit can be tested.
5.2.4 Deleting the Reference Value
Briefly press the “PD” button to delete the reference value and set the wavelength to “0.00dBm”. Push
and hold to delete all the reference values (of all wavelengths) to “0.00dBm”.

5.2.5 Storing the Current Reference Setting
Press to store the current reference setting. The stored data will be saved even when the device is
turned off. The device will return to the measuring mode and automatically return to “dB” after storing
the results.
Note: the reference value is displayed but not saved until the “REF” button is pressed . No data will be
stored if the device is turned off before saving the data.
5.2.6 Discarding the Reference Value of the Current Setting
Press to discard the reference value of the current setting and delete currently displayed data. The
device will return to the original mode. It will return to a measuring mode and the device will be shifted to
“dB”.
5.3 Operating in “Data Storage” Mode
Press and release to enter the storage mode and review the stored data.
5.3.1 “Page Up” for Checking the Data Numbered from 001 to 999
The first stored record is saved as number 001. Quickly press and release the “Up” arrow button to
check the stored data records up to #999. Press and hold for over 2 seconds to check the stored values
starting from record #990.
