Resistance Measurement; D) Direct Current Measurement - VOLTCRAFT VC-12A Bedienungsanleitung

c) Resistance measurement
Make sure that all parts of the circuit, switches and
components and other objects to be measured are dis-
connected from the voltage and discharged.
Proceed as follows to measure the resistance:
- With the rotary switch, select the measuring
range Ω x1K.
- Now perform the zero adjustment.
- Connect the black measuring line to the
COM socket (5) and the red measuring line
to the „+" measuring socket (6).
- Connect the two measuring tips and wait
until the pointer has stabilised. A value of
approx. 0 Ohm must be displayed. In case of
a deviation, adjust the pointer with the 0 Ohm calibration control (3) to
0 Ohm.
- Read off the measured value on the scale „Ω". Multiply the displayed
value by a factor of 1,000 to get the measured value e. g. 5 Ω (display)
x 1,000 = 5 x 1,000 = 5 kΩ (measured value).
- After completing the measurement, remove the measuring tips from
the measuring circuit and switch the multimeter off (rotary switch posi-
tion: „OFF").

d) Direct current measurement

Never exceed the max. permitted input values in the
respective measuring ranges.
Only make current measurements in circuits up to
max. of 250 V.
