100,000 cts digital multimeters 49
Technical characteristics of the MTX 3292, MTX 3293 (continued)
The 100mV range is available only in Manual mode, by " ".
In the VAC & VAC+DC modes and for signals >1kHz, the range of uncertainty displayed is
given for information only: we recommend using the formulas below.
VLowZ: The error should be slightly greater than the error in VAC.
() limitation at high frequency
() not contractual indicative values (see curves below)
() BP: Freq [kHz] limited to: 15,000/U input [V]
U input [V] limited to: 15,000/Freq [kHz]
Example: U input = 1,000 VAC Max. frequency: 15,000/1,000 = 15kHz
In the presence of a DC component: Additional error: (UDC/U measured) x (0.7% L + 70 D)
Example: UDC = 2V, U measured = 5 Vrms Additional error: 0.28% L + 28 D
- Rejection: common mode >80dB at 50Hz or 60Hz depending on selection
- Automatic or manual selection of the ranges
- Protection by varistors
- Maximum acceptable permanent voltage: 1,414 Vpk
- Specifications valid from: 10 to 100% of the range in the band from 20kHz to 200kHz
- Influence of the peak factor on the accuracy in VAC, V at 50% of the range:
1% for a peak factor < 3.
As soon as the PEAK symbol appears, use the AUTO PEAK mode.
