a) Select function A with the function selector switch for cur-
rents > 400 mA, or function mA for currents < 400mA. When
measuring currents of an unknown magnitude, select the
highest measuring range first.
b) Select the function corresponding to the measured quantity
by briefly pressing the yellow multi-function key. Each time the
key is pressed, alternate switching takes place between AC
and DC, and change over is acknowledge by sound signal.
The symbols DC and ~ AC indicate the selected current
type in the LCD display.
After selection of this function with the selector switch,
the Current type DC is always activated.
c) Connect the measuring instrument in series to the load as
shown (without contact resistance).
Notes on Current Measurement :
* The meter must be used only in power systems, when the
current circuit is protected with a 20 A fuse or circuit
breaker, and the nominal voltage of the system does not
exceed 600 V.
* Make the measuring circuit connections mechanically
strong and secure, so that they do not accidently open. The
conductor cross sections and connection points should be
designed to avoid excessive heating.
* Current ranges up to 400 mA are protected with a FF1.6 A/
600 V fuse.
First switch off the power supply to the measuring
circuit and/or to the load, and discharge any capac-
itors which might be present.
