M127/M128 Auto-Ranging Digital Multimeter

Read common electrical measurements on a single handheld display during suitable test work. The M127/M128 multimeter range offers automatic function and range selection. It is for users choosing the model with the measurements they need.

• ✅ Reduce manual range selection — Automatic function and range selection is stated.
• ✅ Keep a reading visible — Data hold retains a value for review.
• ✅ Set the display on a surface — A rear stand provides a viewing position.
• ✅ Choose broader test functions — M128 adds current, capacitance, diode and continuity modes.

M127 and M128 have different measurement limits

M127 is the four-thousand-count option, with named voltage measurement up to four hundred volts and resistance up to forty megohms. M128 is six-thousand-count, with named voltage up to six hundred volts and additional current and capacitance modes.

Neither the display range nor an NCV indication establishes a safe measurement category. Confirm ratings on the actual meter and leads, use the correct terminals and follow the instructions. Two AAA batteries are required and are not included.
