OTHER INSTRUMENTS / ADAPTERS / ACCESSORIES A 1143 Euro Z 290 A


The A 1143 Euro Z 290 A is a professional portable high current impedance tester. It performs high precision line and high precision fault loop impedance measurements in environments up to CAT IV / 310 V.


MEASURING FUNCTIONS:


• High precision line impedance; • High precision fault loop impedance; • Contact voltage.


KEY FEATURES:


• Independence: instrument is designed to work independantly or in conjunc- tion with: MI 2086 Eurotest 61557, MI 3101 EurotestAT, MI 3105 EurotestXA and MI 3321 MultiServicerXA.


• Range widening: adapts the instruments to read from 0.1 mΩ up to 19.99 Ω.


• Multi-system testing: works on both single phase and 3-phase systems (115 V to 440 V).


• IPSC and IPFC calculation: IPSC and IPFC readings calculated up to 400 kA.


• 4-wire measurement for elimination of voltage drop on measuring leads.


• Comfortable carrying: all the acces- sories are put in the strong, rugged, durable case of the instrument.


• LCD: Built-in LCD for standalone meas- urements.


APPLICATION:


• High accuracy loop and line measure- ments;


• Power transformer and motor winding measurement.


STANDARDS:


Functionality: IEC/EN 61557 Other reference standards for testing:
