(∗∗) BP : Freq [kHz] limited to : 15,000 / U applied [V]
U applied [V] limited to : 15,000 / Freq [kHz]
 Example : U applied = 1000 V AC  max. frequency : 15,000 / 1000 = 15 kHz
In the presence of a continuous component :
Additional error : (U DC / U measured) x (0,7% + 70 D)
 Example : U DC = 2 V, U measured = 5 Vrms  additional error : 0.28% + 28 D
Rejection: common mode > 80 dB at 50 Hz or 60 Hz depending on selection
Automatic or manual selection of ranges.
Protection by varistors.
Maximum permanent acceptable voltage: 1000 V ACrms.
Specifications valid from:
20 to 100% of range in the 20 kHz to 200 kHz MTX 3283 band,
20 kHz to 100 kHz MTX 3282
20 kHz to 50 kHz MTX 3281.
 As soon as the PEAK symbol is displayed, connect to AUTO PEAK :

Influence of peak factor on accuracy in V AC , V AC+DC at 50% of the range:
• 1% for a peak factor between 4,5 and 6
• 5% for a peak factor between 6 and 9
DC voltage
V DC
In "DC" mode, you measure the value of a DC voltage or the DC component of
an AC voltage, once the filter is activated, see p. 14.
 The 100 mV range is present in MANUal mode only.
(∗) - Recovery after triggering of protection (> 10 V) app. 10 s.
- Protection 1 minute max.
(∗) - Accuracy with filter (p. 14) and REL mode activated (∆ measurement).
- Recovery after release of the protection (> 10 V) approx. 10 s.
- Protection 1 min. max.
Specifications valid from 0 % to 100 % of the range
Rejection: common mode: > 120 dB with 50 Hz and 60 Hz acc. to selection
serial mode: > 60 dB with 50 Hz and 60 Hz acc. to selection
Automatic or manual selection of the ranges. Protection by varistors.
