6,000- and 60,000-count digital multimeters
Technical characteristics of the MTX 3290
Accuracy:
“n% L+n D” means
“n% of the reading
+ n Digit”
(see CEI 485)
Only values with tolerances or limits are guaranteed values.
Values without tolerances are given for guidance (standard NFC42670).
The technical specifications are guaranteed only after 30 minutes of warming up.
Except as otherwise indicated, they are valid from 10% to 100% of the measurement
range.
DC voltage
In the "DC" mode, you measure a direct voltage or the DC component of an AC
voltage (
filter activated
).

AC and AC+DC
voltages
With this function, the user can measure the true RMS (TRMS) value of an AC
voltage with its DC component (no capacitive coupling) or without its DC component.

1) See the typical curve of the 300Hz filter.
2) The LCD indicates "+OL" above +620V, "-OL" below -620V or above 620VRMS.
3) From 1kHz, the measurement must exceed 15% of the range.
