- Application -

Research and development of automobiles (8841)

In vehicle and engine running tests, the relationship among various

parameters must be examined. Multi-channel recorders are necessary to

accomplish this. While 8841 has retained the size of its predecessor, the

8840, it allows recording with 16 analog channels + 16 logic channels.

Using the DC POWER ADAPTER 9433 enables operation using the vehicle's

battery (+12 V/+24 V).

* With the 4ch ANALOG UNIT 8946 (4-channel unit) attached.

■ Engine tuning

Allows the balance between boost, oil pressure,

air fuel ratio, ignition timing, engine speed,

injector aperture, etc., to be observed and

recorded as waveforms.

■ Analysis of engine characteristics

The pressure waveforms of injection pipes and fuel-

injection pumps, etc., can be recorded and stored

in the internal memory and then superimposed on a

reference waveform for analysis.

■ Evaluation of electrical circuits

Quality evaluation of meter boards for use in

automobiles can be performed by recording and

evaluating analog waveforms.

Waveform judgment

After defining a reference waveform bounding area,

it is possible to check whether waveforms go outside

this reference area. As opposed to simple voltage level-

based triggering, even complex waveforms can be

evaluated quickly and reliably, because both the level

direction and the time axis direction are taken into

consideration simultaneously.

* Registered patent no. 2028013, in Japan

Evaluation of machines and materials

Pressure waveforms can be measured and recorded simultaneously at various

points of hydraulic machines to determine whether such machines are

operating normally. Using, for example, the recorder's X-Y recording function,

performance dispersion check can be conducted by recording the relationship

between one cycle operation command signal for an injection molding machine,

the pressure and the position change.

■ Analysis of injection molding machine operation

The quality of molded products can be evaluated by recording the

relationship between the injection molding machine's operation

command and the pressure and position change.

■ Analysis of tensile tests

When conducting stretching characteristic test and tensile test of

steel tubing, the relationship between load and contraction can be

recorded.

Recorder function X-Y display

The recording time is unlimited in the case of

recording an X-Y plot of two analog channels. The

channel combination is arbitrary. The X-Y plot can be

viewed on the screen, and it can also be printed out as

many times as desired, making this more useful than

what is offered by standard X-Y recorders.

■ Recording of motor rush current

The rush current occurring when the power to a motor or a relay is

turned on can be accurately measured as a waveform.

■ Servo-controller analysis

The operation of a servo-controller utilizing a PWM inverter and

used to control a general motor can be accurately measured as a

waveform.

Fast response recorder function

The 8841 and 8842 have a recording function which can print out data onto paper in real-time. Recording

continues until the recording paper (30 m per roll) is used up. The recorder functions offered by the 8841 and 8842

outperform others in the way that the recorder's pen response is extremely fast in relation to the sampling speed. The

maximum sampling speed is 1 µs, which is the same as the memory recorder function speed.
