Metrix MTX 3250 User Manual

Technical Specifications
48 50,000-count Benchtop Multimeter
Technical Specifications
@ Note
Only assigned tolerance values or limits are guaranteed values. Non-
tolerance values are for information (NFC 42670 standard).
Please note: "n%L +nUR" means "n% of reading + n Representation Unit"
according to CEI 485).
Technical specifications are only guaranteed after a 30-minute warming up
period.
Measuring voltage

“TRMS” alternating
voltage
@ Note
On this position, users can measure the rms value of AC voltage with its
direct component (no capacitive coupling) : "TRMS" measurement.
