Step types in a sequence
 
The various sequence steps are offered in order to create a test sequence. They depend on the connected test device and the selected sequence type (device/IZY sequence). The sequence steps can be divided into the following types:
 
Measurements (analyzed automatically)
These sequence steps are measurements that run on the test device. They require one or several thresholds. The measurement can be analyzed automatically by comparing the measured values with these thresholds. This step type can be used in device sequences and in IZY sequences with a connected test device.
 
Attention!
Please observe the operating instructions of the respective test instrument.
 
User-analyzed measurements
Like measurements with automatic analysis, the measurements run on the test device in these sequence steps. However, they do not require thresholds, as the user conducts analysis at the end. This sequence step can also be used in device sequences and in IZY sequences with a connected test device.
 
Manual input
This sequence step does not require a test device. An input screen is created in which the measurement task is described and a field is shown for manual entry of the measured value. The measured value can be analyzed automatically by configuring the sequence step with a threshold and an analysis criterion. This sequence step can only be used in IZY sequences.
 
Checks
This sequence step can be used to conduct checks in the connected test device that require a positive result in order to progress to the following steps. The next step will not be executed in the case of a negative result. However, users can configure manual skip or repeat check functions. The sequence step can be used in device sequences and in IZY sequences with a connected test device.
 
Probe check for probe connector P1: Please perform a probe check after each test.

If probe P1 is used in a test sequence, it is imperative that a test step „probe check“ with PROBE: „Probe connector P1“ be performed in the corresponding test sequence. Background: In addition to assuring that a probe is connected to probe connector P1, the probe check verifies at connector P1 as to whether the probe fuse is in faultless condition.
 
 
Attention!
If there is a fuse defect in test probe P1 after having started the test, all subsequent measurements which are performed with this measurement path are erroneously rated as good!
 
Fuse check AP* (for test instruments with application part jacks)
If the AP jacks are used in a test sequence (regardless of whether the connections are used for measuring or for implementing test condition „AP > PE“ (application part to earth)), it is necessary to perform an additional test step „fuse check AP“ for verification purposes. This test step is to ensure that the two AP fuses are faultless.
 
 
Attention!
Performing measurements for which AP connections are used, while one or both AP fuses are faulty, may lead to incorrect measured values.
 
Visualized checks
This sequence step can be used to conduct checks in the connected test device that may have several prescribed results. Users specify which results are required to pass the check during configuration of the sequence step. The sequence step can be used in device sequences and in IZY sequences with a connected test device.
 
Trigger time
This sequence step triggers a test procedure for PRCDs in the connected test device. The measured value can be analyzed automatically by configuring the sequence step with a threshold, analysis criterion and display texts. The sequence step can be used in device sequences and in IZY sequences with a connected test device.
 
Visual inspection
This sequence step relates to device sequences in the test device or IZY sequences in the IZYTRONIQ. It shows several analyzable visual inspection questions – that can be defined during configuration of the step – which the tester must answer when performing the step. This step can be used in a device sequence and in an IZY sequence.
 
Test instruction
This sequence step relates to device sequences in the test device or IZY sequences in the IZYTRONIQ. It issues an alert that must be confirmed by the tester when performing the step. This step can be used in a device sequence and in an IZY sequence.
 
Push/print
This sequence step switches all connected test devices to PUSH/PRINT mode. This means that tests that have been performed can be transferred from the test devices to IZYTRONIQ at the push of a button and then saved there. This step type can only be used in an IZY sequence with connected test device/s.
 
Subsequenz
A sequence can be designed modular. To this, repeatedly occurring test steps can be integrated into one subsequence, which can be embedded into another sequence, if required.
