Types of Sequence Steps

A wide variety of sequence steps are offered for the creation of test sequences. They depend on the connected test instrument and on the selected sequence type (device/IZY sequence, see „Types of Sequences“). Sequence steps can be categorized into the following types:

These sequence steps are measurements which are performed by a test instrument. They necessitate one or more limit values. The measurement can be evaluated automatically by comparing the measured values to these limit values. This type of step can be used in instrument sequences as well as in IZY sequences with connected test instrument.

Attention!

Please observe the operating instructions of the corresponding test instrument!

As is also the case with automatically evaluated measurements, measurements in these sequence steps are performed by the test instrument. However, no limit values are required because the user evaluates the measurement after it has been completed. In this case as well, the sequence step can be used in instrument sequences as well as in IZY sequences with connected test instrument.

No test instrument is required for this sequence step. An entry window is generated in which the measurement task is described and a field is displayed to which the measured value can be entered manually. The measured value can be evaluated automatically by configuring the sequence step with limit value and evaluation criterion. This sequence step can only be used in IZY sequences.

Checking can be conducted in the connected test instrument with this sequence step and positive results are a prerequisite for the following steps. In the event of negative results, the next step is not executed. However, manual override and repetitions of the check can also be configured. This sequence step can be used in instrument sequences as well as in IZY sequences with connected test instrument.

• Probe test, probe connection P1: Please execute a probe check after completing each test.
If probe P1 is used in a test sequence, a “Probe Test” step with “PROBE: Probe Connection P1” must be included in the respective test sequence. Background: In addition to assuring that a probe is connected to probe connection P1, the probe test at connection P1 also determines whether or not the probe’s fuse link is intact.

Attention!

If the fuse at test probe P1 is defective after testing has been started, all subsequent measurements conducted using this measuring path will be incorrectly evaluated as good!

• APP fuse test (for testers with sockets for applied parts)
If the APP sockets are used during a test sequence (regardless of whether the connections are used for measurement or in order to implement the “APP > PE” test condition [applied part to ground]), the “APP fuse test” step must be additionally conducted. This test step ensures that both APP fuses are intact.

Attention!

If measurements are conducted for which the APP connections are used, and if one or both of the APP fuses are defective, incorrect measured values may result.

Checking can be performed in the connected test instrument by means of this sequence step, which can have multiple predefined results. The results required in order to pass the test are specified during configuration of the sequence step. This sequence step can be used in instrument sequences as well as in IZY sequences with connected test instrument.

This sequence step initiates a test sequence for PRCDs in the connected test instrument. The measured value can be evaluated automatically by configuring the sequence step with limit value, evaluation criterion and display texts. This sequence step can be used in instrument sequences as well as in IZY sequences with connected test instrument.

In the case of device sequences in the test instrument or IZY sequences in IZYTRONIQ, this sequence step displays several assessable visual inspection questions that can be entered while configuring the step, which have to be answered by the inspector when performing the step. This step can be used in instrument sequences as well as in IZY sequences.

In the case of device sequences in the test instrument or IZY sequences in IZYTRONIQ, this sequence step displays an instruction which has to be acknowledged by the inspector when performing the step. This step can be used in instrument sequences as well as in IZY sequences.

All connected test instruments are set to PUSH-PRINT mode by this sequence step. This makes it possible to transfer tests performed by the test instrument to IZYTRONIQ and store them by simply pressing a key. This step can only be used in IZY sequences with connected test instrument(s).

Sequences can be structured in a modular fashion. Recurring test steps can be combined into a subsequence to this end, which can be integrated into another sequence if required.
