Professional multimeter for electricians

The TENMARS YF-78 is a 3 1/2 digit LCD multimeter built for professional electrical testing. It provides automatic zero adjustment and polarity indication for straightforward measurements. The unit operates on a single 9V battery (not included) and is supplied new in a single pack.

Practical limits of the LCD display

The screen shows a maximum reading of 1999 counts with decimal point and symbol display. Sampling occurs at 2.5 times per second, which suits steady or slowly changing signals. An "OL" indicator appears automatically when the input exceeds the selected range. A "BAT" symbol warns when battery voltage drops below the operating threshold.

Build quality and daily implications

The red handheld body is designed for regular field use with a battery life of approximately 200 hours. Manufacturer coverage includes three years for parts and one year for labour. The single-box package contains the meter only, so test leads must be sourced separately before the first job.
