■ Accuracy This the difference between the signal's true value and the value displa It may differ according the calibre and usually expressed follows: E reading counts ■ Crest factor This the ratio the peak (highest) value signal the RMS value.fr . • Only use accessories perfect condition.), you will longer protected the event a fault overvoltage. Detailed product brochures can downloaded from www. multimeter's bandwidth indicates the instrument's ability process these signals. ■ Safety rules and good practice: • Use measurement instruments and accessories which are suitable for the application and measurement conditions. Otherwise, opt for TRMS instrument, preferably offering selection AC+DC coupling. you replace them with more economical models, even worse, pieces metal (copper wire, aluminium foil, etc. There direct relationship between the resolution, the calibre and the number of display counts: Resolution = Calibre No. f \ ^ V \TT71J r ed. • the weakest element that defines your level protection.

Thus, its mechanical protection, leakproofing, weight, handling and general ergonomics are crucial factors for the instrument's reliability, life span and operational effectiveness. ■ Number display points This indicates the instrument's maximum display capacity. you use accessories with lower category or voltage rating than your measuring instrument, reduces the overall safety level guaranteed your measuring system. counts ■ Bandwidth This the frequency range within which the multimeter can measure accurately. • High-rupture-capacity fuses are safety elements
