Safety Precautions
Do not remove the case. The instrument's internal components carry high
voltages and are extremely dangerous.
For internal inspection or adjustment, contact your nearest YOKOGAWA
dealer.
If there are any symptoms of trouble such as strange smells or smoke coming
from the instrument, turn the power OFF immediately, and remove the battery
pack or the power cord from the outlet. If such an irregularit y occurs, co ntact
your YOKOGAW A dealer .
Nothing should be placed on the power cord. The cord should be kept away from
any heat sources. When unplugging the pow er cord from the outlet, neve r pull
by the cord itself. Always hold and pull by the plug. If the power cord is
damaged, contact your dealer for re placement.
Always unplug the power cord from the outlet, and check that all externally
connected wires and cables are removed before moving the instrument.
=> Otherwise, the cords can become damaged, causing fire or electric
shock.
Be sure to unplug the power co rd from the outlet during lightning storms.
=> Fire, electric shock, or malfunction can result.
Do not use old and new batteries at the same time.
=> Explosion or leakage of the batteries can result, caus ing fire, injury, or
contamination of the surrounding area.
Check the polarity of the batteries (plus/minus orientation) before installing them.
=> Incorrect orientation can result in explos ion or leakage of the batteries,
causing fire, injury, or contamination of the surrounding area.
If the instrument experiences an abnormality, do not attempt to repair the
instrument your self.
=> Electric shock or damage can result. Also, any repairs conducted without
authorized consent will not be covered by the product warranty.
Never disassemble or rework the instrument.
=> Fire, electric shock, or malfunction can result.
When handling parts that open and close, such as when changing the battery,
take care not to pinch or injure your finger.
See below for operating environment limitations.
This product is a Class A (for industrial envir onments) produ ct. Operat ion of
this product in a residential area may cause radio interference in which case
the user will be required to corre ct the interference .

General Handling Precautions
Take care not to damage the instrument by dropping it.
Unplug During Periods of Extended Non-Use
Unplug the power cord from the outlet. Remove the dry cells. Failure to
remove the battery pack during long periods of non-use can cause the
battery fluid to leak into the instrument, causing damage.
Do not place any other instrument or anything containing liquid on top of the
instrument. Doing so can lead to malfunction.
Since the LCD screen is very vulnerable and can be easily scratched, do not
allow any sharp objects near it. Also never expose it to vibrations and shocks.
Do Not Install the Instrument in Any of the Following Places
・ Humid or dusty areas
・ On an unstable surface
・ In direct sunlight or in locations such as automobiles where the
temperature can become high
・ In a location where it may become vibrated or shocked
・ Near sources of heat such as heating appliances
The IEC61010-1 pollution degree and overvoltage category of the instrument are
as follows.
・ Pollution degree 2
Pollution degree refers to the degree of adherence by a solid, liquid, or
vapor that reduces the withstand voltage or surface resistance factor. It
is a number that expresses the degree to which an instrument or one
of its components may become poluted while being used.
Pollution degree 2 applies to normal indoor atmospheres. It
applies only to normal or non-conductive pollution, but
conductivity may occur temporarily depending on
concentrations.
・ Overvoltage category II
Overvoltage category (installation category) is a number that defines
excessive voltage, and includes regulations for impulse withstand
voltage.
Overvoltage category II applies to electrical equipment that is powered
by a fixed installation such as a distribution board.

light. You can specify a fixed range. The setting range is -30 dBm
to +20 dBm
The user need not set zero manually.
The wavelength sensitivity can be corrected in the range from
400 to 850 nm (in 1 nm steps). Accurate measurements can be
obtained by matching with the wavelength of the light source
being measured.
You can set a reference value and display the change in level
relative to the reference value (units: dB).
You can switch the displayed units between dBm and W.
When W is selected, mW, uW, or nW is automatically selected
and displayed according to the optical power.
You can also fix the displayed units at mW.
The number of measured data values averaged is fixed at 20.
A moving average is taken every measurement interval.1
When measuring at high NA, you can correct error due to
angular incidence characteristics of the sensor. The setting range
is 0.500 to 2,000 (in 0.001 steps). However, the correction value
must be selected from the NA correction coefficient table in
appendix 1.
