The DCM310 and DCM320 are suitable for the installation, maintenance, and testing of electrical systems. Both measuring devices can measure alternating currents from 0.1 to 400 A and offer a "Data Hold" feature to freeze the displayed value. This is a useful function in tight situations where the display is difficult to read. The DCM310 provides a "Max. Hold" function that automatically saves and displays a maximum value measured over a certain period. The DCM320 has the advantage of measuring ranges for both alternating and direct voltages up to 600 V, as well as resistance up to 20 MΩ. Additionally, it features a continuity test up to 20 Ω. User safety is ensured by the measurement category CAT III / 600 V.
