MI 3300 PAT Demoboard Introduction

1. Introduction
PAT Demoboard is intended for demonstration of electrical equipment safety
management. Typical applications are:
•Presentation of safety management of electrical equipment on seminars,
courses.
•Presentation of typical safety problems on electrical equipment.
•Practical demonstration of measuring instruments (performing tests, making right
connections, analysis of measured results).
Different values of electrical parameters that are usually checked during an electrical
equipment safety test can be simulated. Error states can be switched On or Off.
Electrical parameters that can be simulated are:
•Continuity of equipotential bonding
•Insulation resistance
•Leakage current
•Touch leakage current
•Polarity of cables
•Functional operation
A practically unlimited number of different equipment (portable and handheld
appliances, machines, switchgears) can be simulated by using different demonstration
tables. Eight tables are included in the standard set.
On demand the PAT Demoboard can be simple upgraded with new demonstration
tables (special applications, country design etc) For eventual upgrades contact
METREL or your local distributor.

MI 3300 PAT Demoboard Safety warnings

2. Safety warnings
•Only qualified personnel who are familiar with the demoboard and measuring
instruments may use PAT Demoboard!
•Use only original demonstration tables provided by the manufacturer!
•The PAT Demoboard must be considered as a real piece of electrical
equipment. The simulated faults are real ones. Despite of the fact that the
simulated leakage currents are kept at relatively low levels it is strictly
forbidden to touch any of the accessible metal parts inside the simulation area
during the demonstration!
•The PAT Demoboard will work only if connected to a properly earthed TN or
TT outlet. The Ready lamp must lit green for normal operation of the
Demoboard.
If red light is blinking and buzzer sounds immediately disconnect the
demoboard from the mains and check the supply connections !
•Special care must be taken if performing HV (withstanding) tests. All safety
measures must be considered as if testing real electrical equipment.
•Always check that the current of HV test equipment is limited to a low level
(<3.5mA) when performing withstanding tests on PAT Demoboard.
•If the equipment is not used in a manner specified by manufacturer, the
protection provided by equipment may be impaired.
•Use of Demonstration board in a way not specified in this User Manual could
damage the board.
•Do not use Demonstration board in case of any damage noticed!
•Only an authorised person may carry out servicing of Demonstration board!

5. Demonstration tables information
5.1. General notes:
•The description tables contain following information:
- Simulated values for normal and error conditions (“Error values”).
- Indicative test results for typical measurements.
- Position where simulated are applied in brackets under “Simulation between
contacts”
•The “Error values” (simulated values, shown in error fields of the tables) in the
description tables are valid only for one fault switched ON at the same time.
If more than one fault is simultaneously the “Error values” are summarized.
•Individual demonstration tables are recognized on basis of the information stored
in the RFID TAG (legend of errors, simulation values). The TAGs are placed in
the lower left corner of each table. The TAG information is read by the PAT
Demoboard if it is put correctly on the instrument.
•The values of errors (resistances and capacitances) in description tables are
informative only. The actual inaccuracy is up to ±10%.
•If the outputs of measuring instruments are not galvanically isolated an additional
error of up to 10% can occur on instrument’s reading.
