Measuring
ƽ
Do not exceed the maximum permitted input values. Do not touch any circuits or
parts of circuits if there could be voltages higher than 50 V ACrms or 75 V DC present
within them. Danger to life!
Before measuring, check the connected measuring accessories for damage such as,
for example, cuts, cracks or squeezing. Never use defective measuring equipment!
Danger to life!
During measuring, do not grip beyond the tangible grip range markings on the test
prods and the probe converter.
Measuring is only permitted when the battery and fuse compartment is closed. When
the compartment is open, all measuring jacks are mechanically secured against inser-
tion.
Ꮨ
You may only connect the two measuring lines to the measuring device that are requi-
red for measuring operation. Remove all measuring leads not required from the device
for safety reasons.
☞
The display shows the corresponding connection sequence of the measuring sockets for
each measuring function. Observe this when connecting the measuring leads to the mea-
suring device.
If “OL” (overload) appears on the display, you have exceeded the measuring range.
a) Switching on the Measuring Instrument
Turn the rotary control (4) to the corresponding measurement function. To switch off turn the rotary con-
trol to “OFF”. Always turn the device off when it is not in use.
ƽ
Prior to working with the meter, you have to insert the enclosed battery.
Insertion and changing of the battery is described in the “Cleaning and Maintenance” chapter.
Add this: Measure the voltage before the Prob converter (CLA40) be removed from the DMM
(VC280)
