4 basic steps for area evaluation - operation examples - this is a fail result screen. the background is red, making the status easy to discern also from a distance. the "configure" menu at the top of the screen opens a list for controlling the time axis and making other settings. in the above example, 1div = 100s is selected. operation is very simple, using the cursor keys while watching the screen. to accept a setting, press set. to switch between different screens, use the menu keys at the top. measure a "good" waveform and use it to create an evaluation area. load the measured waveform into the "editor" window. (you can also create a new area from scratch without loading a waveform.) based on the loaded waveform, create an evaluation area by expanding the graph in the vertical and horizontal plane. the amount of shift is specified in div increments. by placing a box frame around a section, you can enlarge or reduce a specific segment of the area. simultaneously perform area and numeric evaluation. the screen shown below is an example for a pass result, using a green background. the overall evaluation result is shown at the top left, with details shown below this and numeric results displayed at the bottom of the screen. simple operation the "unit" menu at the top of the screen opens a list for controlling the voltage range and making other settings. in the above example, 1div = 1v is selected.

(only with model 8731 -10 ) when tiling the screen horizontally, display resolution is reduced by a factor of 2, but... the inputs of model 540. .- (2-channel model) are shown below. the m3.5mm screw terminals are convenient when designing the wiring layout of a production line. for different requirements, specifications can also be changed to bnc connectors. (please contact your local hioki distributor for details.) for safety, all inputs are isolated from chassis ground and from each other. two channels for further enhanced performance when performing 2-channel evaluation with the 540. .- (2-channel model), you can tile the screen horizontally into two sections. on screen, this means that display resolution is halved, but evaluation precision is not affected. the internal processing memory continues to perform highly accurate evaluation using the full screen resolution. evaluation screen can be divided into two windows without impairing resolution because area evaluation is based on screen display pixels, complex donut-shaped patterns such as shown at right can also be evaluated. evaluation devices from other manufacturers use a / d conversion and base their a rea assessment on digital values. therefore, they can only judge whether nor not the upper and lower limits have been exceeded. models 540- .- and 540. .- on the other hand can also perform fail evaluation in the center of the range, something that is not possible with competing products. (x-y measurement is possible only with model 540. .- ) time axis evaluation of x-y lissajous waveform and donut-shaped patterns

7 output timing of evaluation result - how it works - external dc power can be 12v or 24v, and control signal input also operates at this voltage. using the internal isolated 5v power supply for control is also possible. because the terminals are isolated from chassis ground, connection of a sequencer, relay bank, or other device with separate ground potential presents no problem. external control connectors insulated from chassis the diagram below shows the evaluation output cycle when performing area evaluation only for a 1khz sine wave signal. when auto store is selected, data store processing occurs after the evaluation processing step. the evaluation time and evaluation cycle for numerical processing depend on the processing type and recording duration, and also on the evaluation waveform. evaluation result output timing trigger mode: continuous evaluation time: 70 ms max.
