6,000- and 60,000-count digital multimeters
Technical characteristics of the MTX 3290 (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:
6mA range: Measuring a strong current for a long time can cause a temperature
rise in some components. In this case, it is necessary to wait some time for the
metrological characteristics specified in 6mA to be restored.
