WARNINGWARNING

You are cautioned that changes or modifications not approved in this document could void yout authority to operate this equipment. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. To avoid electrical shock, do not open the cabinet. Refer servicing to qualified personnel only.

Precautions for Use

Use batteries

At the same time, can not use different style or different capacitance batteries. And only charge the rechargeable batteries.

Avoiding condensation problems

As much as possible, avoid sudden temperature changes. Do not attempt to use the drive immediately after moving it from a cold to a warm location, to raising the room temperature suddenly, as condensation may form with in the drive. If the temperature changes suddenly while using the drive, stop using it and take out batteries for at least an hour.

Storage

When long time no use,must take out the batteries to avoid destroying the device.

On/Off and Permanent On

Press button will turn on the meter .

Press button again for two seconds or more will

turn off the meter.

This meter has a power-saving function, normal

boot and ten minutes without any operation, the device will automatically

shut down. If you need to shield this function and enable the meter keeps

on working, only need to press the button and hold when you

boot the instrument. After two seconds, the meter display will show "PERM"

which means permanent power on.

Backlight Function

Under boot status, short press the

button, you can control the backlight function

on or off. The backlight function is used when you want to use the meter

at night or darker occasions.

Wavelengths

According to the project, we need to measure

optical signals of different wavelengths. Then we need

to select a corresponding wavelength to measure the

optical power. If the wavelength needs to be measured

does not match with the wavelength we select on the

optical power meter, it will lead to the measuring values

meaningless.

Press button after booting, the meter will

switch to the measure status of a corresponding

wavelength successively, and show on the display.

This series of optical power meter calibration measured

wavelength are:850nm, 1300nm, 1310nm, 1490nm,

1550nm,1625nm.

Wavelengths

The instrument has been equipped with activated

wavelength identification function by the factory, and users

can manually turn on or off this function. In the boot mode,

please press the combination key " " and " ", if

the center of the screen shows NO, which means the

wavelength identification function has been turned off;

but if the center of the screen shows EN, which means it

turned on. When the wavelength identification function

starts, and connects with laser source which has wavelength

identification function, the optical power meter can identify

the current output wavelength and automatically switch to

the wavelength to measure.

Unit

button can be used to change the

display unit of the measurement data to meet the

different requirement. When press and hold this

button for two seconds, the display will successively

show the dBm value and mW/uW value .

The numeric relationship between mW value and dBm value is:

10lg(mW)=(dBm)

Page 13

Reference

Button is used to set or check the

reference value. Short press this button, the display

will show 'REF' and the dBm value which has been

set up. When long press for two seconds or more,

the device will use the current measurements to

overwrite the original setting value and set it as a

new preference value. Meanwhile the 'REF' sign

will flash three times on the display. After that will

show the difference(dB) .

(Each wavelength can set their own reference value)

Charge

5V_500mA

The instrument has a charging function. When use rechargeable

batteries and a low battery indication shows on the instrument, you

should promptly shut down it and recharge. Long time undervoltage

will shorten the lifetime of the rechargeable battery.

Connect the AC adapter to the device correctly, it can charge

Automatically. Besides, computer USB port can also be used for

charging. The battery remaining indicator keeps flashing during

charging. It will stop when the charging is finished. The battery

has finished the fast recharge and can be used directly. If you do not

stop recharging at this time, the in strument will continue the trickle

charge state, using small current to supply natural discharge. But this

process is not more than 48 hours.

The instrument can still be used while charging. But do not plug in

the AC adapter when it is not rechargeable battery inside, or it will

cause a high temperature and combustion, even explosion.

Meter Maintenance and Calibration

General maintenance

Optical fiber connect the adapter should avoid contacting with hard objects and keep clean.

Should be stored in a dry and ventilated place to avoid moisture.

When un use for long time,should remove the batteries before storage.
