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 rst 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.
As soon as “1” (towards the left side of the display) appears on the display, you have exceeded
the measuring range. Select the next higher measuring range
The voltage range „V/DC“ has an input resistance of >10 MΩ, the V/AC range of >4.5 MΩ.
With the digital multimeter, the automatic range selection (auto range) is active in all measuring
functions (except for currency measuring ranges). This function sets the right measuring range
automatically.
