Metrix MTX 3250 User Manual

Technical Specifications
50,000-count Benchtop Multimeter 49
Technical Specifications
Measuring current
ADC current
In "DC" mode, users can measure a direct current value or an alternating
current’s direct component.
AAC,
AAC+DC
TRMS current
@ Note
In "AC" and "AC+DC" modes, users can measure an alternating current’s rms
value with/without its direct component (no capacitive coupling in "DC" mode).
Results < 0.2 % are not displayed.
@ Note
Specifications for direct current superimposed on a sinusoidal signal in the
40 Hz to 10 kHz band, valid from 10 to 100 % of rate.
For the mA and µA range, the "AUTO PK" mode is always active:
Additional error of 2 % for a peak factor between 1 and 1.5.
Additional error of 15 % for a peak factor between 1.5 and 2.
Peak factor is 5 for a 10 A range.
In 500 mADC and 500 mAAC+DC:
Voltage drop < 600 mV
Protection 600 Vrms per HPC ceramic-type fuse
Fuse 600 V / 10 A / 50 kA Cos ϕ > 0.9 (6.3 x 32 mm)
In 10 A and 10 AAC (or AC+DC):
Voltage drop < 300 mV
Protection 600 Vrms per HPC ceramic-type fuse
Fuse 600 V / 10 A / 50 kA, Cos ϕ > 0.9 (6.3 x 32 mm)
Fuse can be accessed outside unit.
