Measuring Mode; Switching On The Meter; Measuring Voltage "V - VOLTCRAFT R-200 Notice D'emploi

Measuring Mode

Do not exceed the maximum permitted input values. Do not touch circuits or parts of
circuits if there could be voltages higher than 25 V ACrms or 35 V DC present within
them! Risk of fatal injury!
Before measuring, check the connected measuring leads for damage such as, for
example, cuts, cracks or squeezing. Defective measuring cables must no longer be
used. Risk of fatal injury!
During measuring, do not grip beyond the grip range markings (which you can feel)
present on the test probes.
Measuring is only possible with the housing and battery compartment closed.
You may only connect the measuring leads that are required for measuring opera-
tion to the measuring device. Remove all measuring leads not required from the
device for safety reasons.
If "OL" (overload) appears on the display, you have exceeded the measuring range.
a) Switching on the meter
The meter can be turned on using the dial switch (5). Turn the dial switch to the corresponding mea-
surement function. To switch off turn the dial switch to "OFF". Always turn the device off when it is not in
use ("OFF").
Prior to working with the meter, you have to insert the enclosed batteries. Insertion
and changing of batteries is described in the "Cleaning and Maintenance" chapter.
b) Measuring Voltage "V"
Proceed as follows to measure DC voltages "V/DC":
- Turn the DMM on and select measuring range "V".
- Plug the red single measuring lead into the V measuring socket "E2"
(10) and the black measuring lead into the COM measuring socket "E1"
(13).
- Now connect the two measuring probes to the object to be measured
(battery, switch etc.). The red measuring tip indicates the positive pole,
the black measuring tip the negative pole.
- The polarity of the respective measured value is indicated on the dis-
play together with the current measured value.
If a minus "-" appears in front of the voltage value when measur-
ing DC, the measured voltage is negative (or the measuring tips
have been mixed up).
- After measuring, remove the measuring leads from the measuring object and turn the DMM off.
