The MS 8239D portable multimeter is a compact multimeter suitable for both standard electrical work and automotive electrical systems, featuring two additional functions: DWELL (engine rotation frequency) and TACH (contact closed angle).
The MS8239D multimeter features both automatic and manual measurement range selection modes.
The multimeter includes an auto-off function and can hold current and maximum measured values on the display.
