Pqa - Real Time Measurement Of Network Parameters; Measurement Of Network Parameters In Single Phase Systems - T.I.S. INSTRUMENTS MFT-PRO Quick Reference Manual

4.9. PQA – REAL TIME MEASUREMENT OF NETWORK PARAMETERS
 The instrument can be used for measurements on installations with overvoltage category CAT III 240V
to earth and CAT III 415V between inputs. Category CAT III is suitable for measurements carried out on
installations inside buildings with low voltage (examples are distribution boards, wirings, switches, fixed
installation sockets, electric motors, industrial equipment)
 We recommend holding the alligator clip and the leads respecting the safety area created by the hand
protection (see § 2.4)
 The maximum voltage allowed between inputs B1 and B4 is equal to 460V. Exceeding such a limit
may cause electrical shock to the user or damage the instrument.
