8. MEASURING
Do not exceed the maximum permitted input values. Do not touch any circuits or parts of circuits
if they may be subject to voltages higher than 33 V/ACrms or 70 V/DC! Danger to life!
Before measuring, check the connected measuring lines for damage such as, for example, cuts,
cracks or squeezing. Defective measuring lines must no longer be used! Danger to life!
During measuring, do not grip beyond the tangible grip range markings present on the measuring
prods.
Only the two measuring lines that are required for measuring operation must be connected to
the meter at any time. Remove all measuring lines not required from the meter for safety reasons
before performing the measurement.
Measurements in electrical circuits >33 V/AC and >70 V/DC must only be carried out by special-
ists and technically instructed personnel who are familiar with the relevant regulations and the
ensuing risks.
Ensure before every measurement that the meter is not set to another measuring range. Also
observe that the HOLD button has not been pushed at the beginning of the measurement (display
with the HOLD button pushed: “H”). If the HOLD button is pushed at commencement of measur-
ing, no measured value is displayed!
Observe the required safety notes, provisions and safety measures for intrinsic protection.
Always start your measurements with the largest measuring range. Then switch to the next-lower measuring
range on demand. Before a measuring range change, always remove the measuring prods from the measur-
ing object. When “OL” (= overflow) appears in the display, you have exceeded the measuring range.
a) Switching on the multimeter
The multimeter can be turned on and off using the dial switch. Turn the dial switch (4) to the corresponding meas-
urement function. To switch off, turn the dial switch to “OFF”. Always turn the meter off when it is not in use.
Before working with the meter, you have to insert the enclosed battery. Insertion and changing of
the battery is described in the chapter “Cleaning and maintenance”.
