Operation
The multimeter (referred to as DMM in the following) indicates measured values on the digital display.
The measuring value display of the DMM spans 2000 counts (count = smallest display value). The
measuring device can be used for do-it-yourself or for professional applications (up to CAT III 600 V).
For better readability, the DMM can also be mounted with the clip on the rear.
a) rotary switch (5)
The individual measuring functions are selected via a rotary switch. The measuring range can be selected
manually with this switch.
b) turning the measuring device on and off
The DMM are turned on and off via the rotary switch (5). When the rotary switch (5) is set to “OFF”,
the DMM is turned off. Always turn the measuring device off when it is not in use.
Prior to working with the measuring device, you first have to insert the enclosed batteries.
A 9 V block battery is required for voltage supply. This is part of the delivery. Insert the battery as
described in the chapter “Cleaning and Maintenance”.
Starting the measurement
Do not exceed the maximum permitted input values. Do not contact
circuits or parts of circuits if there could be voltages higher than
25 V aCrms or 35 V DC present within them. mortal danger!
Before measuring, check the connected measuring lines for damage
such as, for example, cuts, cracks or squeezing. Defective measuring
cables must no longer be used. mortal danger!
During measuring, do not grip beyond the tangible grip range
markings present on the test prods.
You may only connect the two measuring leads to the measuring
device that are required for measuring operation. remove all
measuring leads not required from the device for safety reasons.
