Product Description

The Digital Multimeter (hereinafter referred to as DMM) has a high-contrast, 3
liquid crystal display (LCD) with function and measurement unit display.
The individual measuring ranges are selected via the rotary switch in which "auto
range", the automatic range selection, is active. The appropriate range of measure-
ment is set for each application individually.
Further additional functions include:
• "HZ/%" - for indicating the pulse/pause ratio of a signal in %,
• "RANGE" - manual measurement range setting,
• "HOLD" for "freezing" a measuring value,
• "REL" to perform a reference measurement,
• An automatic power-off function (auto power off) switches the DMM off, if it has
not been used for approximately 35 minutes. This makes the batteries last longer.
The measuring instrument can be used universally both at the hobby level and at the
installation or school level.
A compound 9V alkaline battery, e.g. a 6LR61 or MN1604 or 6F22 or 006P type, are
required / used for supplying the power.
A fold-out stand is installed on the rear side of the protection rubber frame. You can
use this to move the measuring instrument into a diagonal position, which makes it
easier to read the display.
