9. Measuring operation
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.
During measuring, do not grip beyond the tangible grip range markings present on the test prods.
Measuring is only permitted with closed housing and battery compartment.
You may only connect the two measuring leads to the measuring device that are required for meas-
uring operation. Remove all measuring leads not required from the device for safety reasons.
As soon as “OL” (overload) appears on the display, you have exceeded the measuring range.
a) Turning the measuring device on
The measuring instrument is turned on again via the rotary switch (5). Turn the rotary switch to the desired measuring
function. Turn the rotary switch to “OFF” to turn the device off. Always turn the measuring device off when it is not in
use (position “OFF”).
Prior to working with the measuring device, you first have to insert the enclosed battery. Inserting
and changing the battery can be found in Section “Maintenance and cleaning”.
