Yokogawa provides simpliciting for measuring in one unit with benefits including:

Luminance, contrast, flicker and chromaticity measurements
Digital and bar graph indications
Shading cylinder type optical system
Luminance measurement range of 0.01 to 40,000 cd/m2
Memory for measured data from 200 displays
GO/NO-GO determination functions
User-specified color calibration coefficients
Light source color calibration coefficients
Easy operation
Compact and lightweight
Battery-driven

Adjust and inspect the luninance, contrast, flicker and chromaticity of displays more efficiently

High cost-performance
Lets you measure luminance, contrast, flicker and chromaticity all with just one device. The lowcost design greatly reduces the product's price.
Digital and bar graph indications
Measurements for adjustment or inspection work are displayed both as digital values and bar graphs. User-specified MIN, MAX and other criteria can be entered for GO/NO-GO testing of production line samples.
Light source color calibration coefficients
Color correction coefficients for three light source types (type A standard light source, three wavelength fluorescent lamp and CRT display) ensure accurate chromaticity measurements for each color and light source.
Excellent PC interface
In addition to a built-in memory with capacity to store measurement data for up to 200 displays, an RS-232 interface port included as standard equipment makes data communication and control from a PC simple.
Easy operation with contact-free system
The shading cylinder type optical system lets you make easy measurements just by moving the sensor within range of the specimen.
- Shading cylinder type optical system
  Lets you set any measurement area

Measurement Functions

Luminance Measurement

Displays luminance as a digital value and bar graph in a range of 0.01 to 40,000 cd/m2. User-specified MIN, MAX and other criteria can be entered for GO/NO-GO testing.

Contrast Measurement

Measures the luminance of the "white" and "black" displays to instantaneously calculate and display the contrast. The calculated contrast is compared with the userset value for GO/NO-GO testing.

Flicker Measurement

Displays flicker ratio (ACrms/DC) as digital values (% and dB) and a bar graph. Useful for flicker adjustment.

Chromaticity Measurement

Chromaticity measurement mode
Displays GO or NO-GO for the measured value based on the userspecified reference color and range.
A different color calibration coefficient can be set for up to 10 different display types and 6 reference colors, enabling more precise chromaticity measurements for each color in each display.

Display modes
(x, y, L), (u', v', L), (X, Y, Z), (Tc, duv, L)

White balance measurement mode
Displays the difference between the RGBL measured values and the target values in real time.

Display modes
(R, G, B) (RGB ratio)

Flicker Measurement

Measures the light's average luminance (DC) and effective flicker value (ACrms) to calculate and display the flicker ratio (ACrms/DC). The flicker of base frequencies between 20 and 90 Hz can be measured by varying the programmable low-pass filter's cutoff frequency.
The flicker correction function enables conversions to flicker ratios (%, dB) defined by JEITA and VESA standards.
