6,000- and 60,000-count digital multimeters
Technical characteristics of the MTX 3291 (continued)
Currents
Three possible modes: DC, AC, AC+DC
In DC mode, you can measure a direct current or the DC component of an
alternating current.
In the AC and AC+DC modes, you can measure the true RMS (TRMS) value of
an alternating current with/without its direct component (no capacitive coupling in
"DC" mode).
DC current
Particular reference conditions:
600µA and 6mA ranges: Measuring a strong current for a long time may cause a
temperature rise of some components. In this case, it is necessary to wait some
time for the metrological characteristics specified in these ranges.
