Follow the steps below to measure DC (A ) currents (VC-523/VC-523 SE only):
• Switch on the DMM using the rotary dial (F) and select the “A ” measure-
ment mode and the predicted measurement range (40 A / 400 A). “A” and the
AC symbol AC will appear on the display.
• Press the “MODE” button to switch to DC mode. “DC” will appear on the
display.
• The display is automatically set to zero when the current clamp is closed.
If there is a strong magnetic field that affects the reading, use the relative
value function (“REL”).
• Press the opening lever (E) to open the current clamp.
• Surround the conductor that you want to measure and close the current
clamp. Position the conductor in the middle between the two triangular posi-
tion symbols on the clamp. Pay attention to the direction of the current. The
positive wire must run from front to back from the current source.
• The measured current is indicated on the display.
• If a negative current is displayed, this indicates that the polarity of the wire
is reversed or the current is flowing in the opposite direction (e.g. solar pow -
ered or charging devices).
• After taking a measurement, remove the current clamp from the measured object and switch off the DMM. Turn the
rotary switch to the “OFF” position.
c) Measuring voltage (“V”)
Follow the steps below to measure AC (V ) voltages:
• Turn the multimeter on and select “V ” mode.
• Plug the red lead into the V terminal (K) and the black lead into the COM
terminal (I).
• Connect both of the test leads to the measured object (e.g. generator or
mains voltage) in parallel.
The “V DC/AC” voltage range has an input resistance of ≥10 MOhm.
• After measuring, remove the test leads from the measured object and turn
the multimeter off.
