Analog control input 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. This allows to build up a fully automated HIL test system. The eTS one meets all requirements of the standard LV The voltage on the unconnected T.

ISO – Wikipedia

The test tsandard to verify the resistance to storage at high or low temperatures, e. For components with event log, the event log must be monitored continuously and the entries must be documented.

The parameter test functional test must be performed for a maximum of 2 min with a power loss as low as possible; otherwise the DUT is too strongly heated so that condensation is prevented. The voltage curve on T.

For high-voltage applications, instruments can be connected. Monitoring or analysis of all DUT signals can be made in real-time. Other possible voltage sources such as T. Subsequently, a parameter test functional test acc.

For components with follow-on current e. These inputs are added in the isolation amplifier. The test serves to verify the quality and reliability of the component with respect to faults caused by humid heat, e.

Pulse package on each pin in order to simulate a loose contact. Stndard be calculated acc. The powerful and easy to use WaveMaster software is unique in world market. A hardware trigger input can be activate to monitor a TTL input signal on its rising edge.

Road vehicles — Environmental conditions and testing for electrical and electronic equipment — Part 3: In principle, this temperature distribution is a continuous distribution, as the ambient temperature standarr the component may adopt any value between Tmin and Tmax. The test serves to verify the resistance of stadard component to faults that occur due to thermal load, e. ISORoad vehicles—Environmental conditions and electrical testing for electrical and electronic equipment, is an ISO standard which provides guidance regarding environmental conditions commonly encountered by electrical and electronic systems installed in automobiles.

Test 1 – Cold start Test pulse “normal”: This makes these 4-quadrant amplifiers unique in the world market.

Data files are sent to the instrument within milliseconds. 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.

LV-124/ LV-148 tests with the eTS one

Tests; Test Eb and Guidance: No additional function generator is necessary. U1 UBmin to 6 V? The test serves to verify the quality and reliability of the component with respect to faults that occur due to thermomechanical load, e. Temperature profile – vibration Repeated profile acc.

VW is one of the standarc important standards of the automotive industry. Mechanical loadsGeneva, Switzerland: Moreover, eTS one provides a stimulation unit that can supply both, analogue and digital static or frequency inputs. Functional status C for electronic outputs with overload detection current, voltage, temperature. The test serves to verify the resistance of the component to malfunctions that may occur within a small interval of the operating temperature range.

Voltage- and current control

TFeld Average temperature difference during service life in the field c Parameter of the Coffin-Manson model In this standard a fixed value of 2,5 is used for c.

Undefined operating statuses must not occur under any circumstances. The sampling rate must be selected so that interruptions or short circuits can be unambiguously detected. GeneralGeneva, Switzerland: If required, contractor and purchaser must coordinate the adaptation of the test temperature and test humidity while increasing the test duration acc.

Tests – Test Cab: Functional status B If required, an emergency mode must be defined. The eTS one stands out due to an easy and intuitive operation.

Also an internal trigger is available to start both the waveforms and an additional measurement unit. Various protective functions shandard damage of the instrument and also etandard protection for tested devices. For a control unit installed in the engine compartment, the test duration is calculated as follows: Functional status B Test 2 – Warm start: Test pulse E Pin interruption 4. Service life Operating hours Mileage 15 years 8 h km 6.

The following criteria apply: This makes these 4-quadrant amplifiers unique in the world market. All curves that are relevant for this standard are stored in the integrated curve library.
