Use the Correct Battery
Use the Correct Battery
Use only a nineĆvolt alkaline battery, IEC type 6LR61,

Do not use rechargeable NiCd (nickelĆcadmium) batterĆ
ies. Their low power capacity and cell voltage will not
support the J17.

Be sure that any power supply you use with
the J17 provides power within the range of 9
to 12 VDC, and that the center contact polarity
of the adapter is positive. A power supply that
does not meet these requirements may damĆ
age the J17.

units shown along the left or right side.
Additional items may appear on the display during
selfĆtest.
The BAT icon flashes

voltage drops below
7.2 V. See page 1Ć8.
One of WHT, RED, YEL,
GRN, or BLU appears
to show the selected
correction factor.
(White is the default.)
The bar graph indicates
the level of the input
signal at the A/D
converter, which affects
the accuracy of the
reading. When using
manual ranging, choose
the range that produces
the longest bar graph
for best accuracy. The
specified accuracy may
not be available if the
graph is at the low end
of the scale.

An RSĆ232 cable is available as an optional accessory
to the J17 (refer to for orderĆ

the J17, and a DBĆ9 female connector for connection to
the computer. (Another common RSĆ232 connector on
computers and terminals is the DBĆ25 connector.
Adapters are commercially available to convert from the
DBĆ9 connector to a DBĆ25 connector.)

This section is included to clarify the function of the
COLOR and START buttons.
The J17 has a button labeled COLOR for use with
certain heads. Pressing this button and toggling
through the separate colors does not give a readout of
the color component of that source. The button is used
when measuring pure color sources to fine adjust the
sensor calibration to that specific color. For example:
the RED mode should be selected when measuring the
output of a red LED.

Saturated colors, which are located on the periphĆ

except on the purple to red boundary. Colors
become progressively less saturated toward the
white achromatic region in the center. The degree
of saturation is a measure of color purity.

The ratio of distances between two colors to a third

The ratio of distances between two colors to a third
color located on a line drawn between them is
proportional to the ratio of intensities of a mixture of
those two colors required to produce the third

The principal disadvantage of the x,y chart is that equal
distances on the diagram do not represent equal
perceived color distances.

Although the colors displayed along an isotemperature
line will appear similar, there will be noticable differĆ
ences. For the best results when setting display color
balance, use the precise color coordinates of the
crossing of the Planckian Locus by the desired color
temperature. For example, x = 0.318 and Y = 0.332 is
the location of D65 (6500 K). Do not use correlated
color temperature alone.
