Measuring Resistances; Testing Diodes - Monacor DMT-2010 Instruction Manual

the individual measurements, otherwise the meter and the test leads
may be damaged.
1) For measurements up to 400 mA, connect the red test lead to the jack
"V Ω Temp Hz% mA µA" (8); for measurements exceeding 400 mA to
10 A, connect it to the jack "10A" (7). With unknown currents, start with
the 10 A range to be on the safe side.
2) According to the intensity of current, set the selector switch (6) to the
following position:
for currents up to 4000
for currents exceeding 4000
for currents exceeding 400 mA to 10 A
3) Once the switch has been set to one of the three current ranges, the
mode "DC current measurement" will be activated ("DC" will be dis-
played). For AC current measurements, press the button "MODE" (3)
["AC" will be displayed]. To return to DC current measurement, press
the button "MODE" again.
4) Insert the meter via the test leads into the circuit to be measured and
read the value on the display. If the red test tip is applied to the nega-
tive pole and the black tip to the positive pole when measuring DC cur-
rents, there will be a minus sign in front of the value displayed.

5.3 Measuring resistances

G
Never measure a resistor when voltage is applied; always measure it
separately, otherwise the measurement will be inaccurate. For this pur-
pose, it may be necessary to solder it out of the circuit.
1) Set the selector switch (6) to the position " Ω
switch has been set to this position, the mode "resistance measure-
ment" will be activated.
2) Apply the test tips to the resistor and read the value on the display. As
long as there is no resistor between the test tips, "OL" will be displayed
to indicate an infinitely high value.

5.4 Testing diodes

G
Never test a diode when voltage is applied; always test it separately,
otherwise the measurement will be inaccurate. For this purpose, it may
be necessary to solder the diode out of the circuit.
