LV covers tests for electric and electronic components for use in motor vehicles up to 3,5 t with a 12 V electric mOhm. Tolerances & standard values. LV Automotive test standard bij Hielkema Testequipment. The LV includes several mechanical, climatic and life tests, such as the K damp heat. ISO , Road vehicles—Environmental conditions and electrical testing for electrical and electronic equipment, is an ISO standard which provides guidance .

Endurance test 1 x test pulse at intervals of 9 s Both tests are carried out in succession. Climatic loads  ISO Road vehicles — Environmental conditions and testing for electrical and electronic equipment — Part 4: Event log entries must standxrd occur. A parameter set is to be selected depending on the input circuitry. The DUT is addressed in the same way as it is in the vehicle circuit.
The test serves to verify the resistance standarx the component to faults, such as deformation or cracks. This electronically generated standard is authentic and valid without signature.
The test serves to verify the resistance of the component with respect to faults caused standrd humid heat, e. The powerful and easy to use WaveMaster software is unique in world market.
For other terminals with “wake-up functions”, the test must also be performed. The total test duration tGes is the sum of top, max and tmax. The intermediate measurements must be carried out as parameter test large.
LV Test equipment at SIBO Electronic
The total number of test cycles is calculated acc. Test condition For the first time, the condensation test must be performed prior to the final specification of the circuit layout hardware freezebut already with DUTs manufactured under conditions similar to standard production, to optimize detected condensation sensitivities, e.
All selections in the instrument are done automatically. Bursts, repetitions and loops make testing easy without any software coding. Schematic circuit E Ground offset 4. The following criteria apply: The respective ramp times between Tmax and Top, max are not included in the test duration.
Data files are sent to the instrument within milliseconds. The sampling rate must be selected so that interruptions or short circuits can be unambiguously detected.
LV-124/ LV-148 tests with the eTS one
The SIB series are linear precision 4-quadrant power amplifiers for fast voltage and current signals – each positive and negative bipolar. The test serves to verify functioning of the component when exposed to high-pressure cleaning. Without any knowledge in software development, construction of ordinary and complex waveforms is dead easy.
If the manufacturing process of the electr. In addition, the electr. Lc124 with frequent brake cycles no misuse, such as uninterrupted brake control operation. The data resulting from the continuous parameter monitoring must be examined for trends and drifting to detect irregularities, aging or malfunctions of the component.
Test 1 – Cold start Test pulse “normal”: Parties to a contract can only obtain this standard via the B2B supplier platform www. Extremely high bandwidth at highest power requirements, necessary for fast signals, characterizes this series. By means of a special memory-shift technology test sequences of any length can be processed without any risk to run out of memory space. Sgandard requirements must be defined and documented in the Component Performance Specifications.
Verification takes place by means of a parameter test small acc. Output voltage and current can be limited and also over temperature shutdown is included. Salt spray test with operation, exterior – spray phases 9.
If fuse elements are available in the load circuit, these may be triggered. Analog Remote Control With an optional isolation amplifier, the instruments have two analogue inputs. Permissible event log entries must be coordinated with the purchaser and must be stipulated. Service life requirements Table 43 shows the typical parameters for the service life requirements. The valid temperature spectrum must be documented in the Component Performance Specifications.
The typical interval of 48 h is divided at the ratio of the part test durations top, max and tmax. Anti-theft alarm No operation system when vehicle is lv1124.
Voltage- and current control
An adaptation of the system to other standards and other DUTs is also possible. Temperature difference during a test cycle: The integrity not up-to-dateness of the non-volatile memories must be ensured at any time. The easy-to-use WaveMaster software, that is standard in scope of delivery, allows to generate waveforms by means of a graphical user interface or via tabular input. However, the test severity must be maintained.
Tests – Test N: Signal Quality Rise time: A parameter test functional test is carried out at each water bath temperature increase by 10 K starting 30 min after beginning of the condensation phase acc. The artificial vehicle network must be coordinated with the engineering department.
