Professional Automotive DMM with USB

The CEM AT-9995 is a professional automotive digital multimeter featuring a USB interface for data connectivity. It provides an oversized high-contrast 4000-count LCD display with bargraph and backlight for clear readings in workshop conditions. The meter includes fused current inputs and overload protection on all ranges for safety during vehicle diagnostics.

Suited for 1 to 12 cylinder engine diagnostics

This meter suits technicians performing RPM measurement on automotive engines with 1 to 12 cylinders using the inductive pick-up. Data hold, relative, max hold and min hold functions support detailed analysis of vehicle electrical systems. Builders who need wireless connectivity should look at alternative models as this unit uses a wired USB interface.

4000-count display resolution decides suitability

The single specification that decides whether this is the right part is the 4000-count display resolution. This count determines the measurement granularity available for voltage, current and resistance readings during automotive troubleshooting. The 4000-count LCD with bargraph provides the visual feedback needed for professional diagnostic work.

Questions about this item

How do I confirm the 4000-count LCD is displaying readings correctly after I connect the inductive pick-up?

The oversized high-contrast 4000-count LCD with bargraph backlight shows live values; use Data Hold to freeze a reading and Relative mode to zero the display for comparison.

The notice says batteries are not included — what else must I supply before first use?

You need to buy batteries locally; the standard package includes the meter, inductive pick-up for 1 to 12 cylinder RPM measurement, test leads and the USB interface cable.

Should I choose the AT-9995 with RS232 or the AT-9995E with wireless USB for my workshop?

The AT-9995 provides a wired RS232 link; the AT-9995E adds wireless USB. Pick the version whose interface matches your existing diagnostic software and cable setup.
