F) Dc Measuring A - VOLTCRAFT VC-666 Bedienungsanleitung

f) Direct current measuring A
Current measuring is possible in three ranges from 0 to 200 mA. All current measu-
ring ranges are provided with fuses and thus protected against overload.
Proceed as follows to measure DC voltages:
- If you want to measure currents up to max. 2000 μA,
set the rotary switch to the position „2000 μA" or the
matching measuring range.
- Now connect the two test prods in series with the
object to be measured (battery, circuit etc.); the display
indicates the polarity together with the currently mea-
sured value.
Never measure currents above 200 mA in the μA/mA range, since
this would cause the fuse to trip. The voltage in the measuring circuit
may not exceed 250 V.
If measuring is no longer possible (measuring value does not change,
etc.), the internal fuse may have been triggered. Fuse exchanged
may only be carried out by a specialist.
- After you finish testing, always switch the measuring device off. Turn the rotary
switch to „OFF".
