Digital Multimeter
USER GUIDE
83003R

1. Overview

This multimeter is characterized by a compact rugged construction with protective
holster and stand. The LCD Screen with 27mm display gives clear readings even
in low light when the backlight can be switched on. Features include dual slope
A/D converter using C-MOS technology for auto-zeroing, polarity selection and
over-range indication. Full overload protection is provided.
Before use you will need to fit a 9V PP3 battery (not supplied) in the compartment
located on the back of the meter. To open the compartment remove the cross
headed screw from the lid and lever open, clip the terminal studs over the battery
terminal caps, close the compartment lid and screw tightly shut.
