6. Operation
GENERAL
• When the range of the measured signal is unknown, start measurement in auto-range
mode, and then select range according to indicated value.
• The display shows “OL” when the present range limit is exceeded. Select a higher range
to continue measurement.
• Do not measure voltages > 600 V or current higher than 1000A. Never turn the rotary
function switch [3] during measurement.
• The device will go in sleep mode when no activity is detected for ±20 min.
• For all measurements: pressing the data hold button [4] freezes the currently measured
value until the data hold button [4] is pressed again. The hold-mode is indicated by the
H-symbol in the display.
• To switch on the backlight, press the backlight button [8], to switch it off, press the
backlight button [8] again. The use of backlight will reduce battery life.
• Peak hold function: for AC measurements, pressing the peak hold button [6] once will
show only the maximum measured value on the display [9], indicated with a P
indicator. Pressing the peak hold button [6] again will show only the minimum measured
value on the display [9], indicated with a P
press and hold the peak hold button [6] for ±3 seconds until the P
MIN indicator. To exit the peak hold function,
MAX or PMIN indicator
disappears.

AC (TRUE RMS)/DC VOLTAGE MEASUREMENT
• Connect the red test lead to the V··CAP·TEMP·HZ jack [11] and the black lead to the
COM jack [10].
• Set the rotary function switch [3] in the
position.
• Use the mode button [5] to choose between AC and DC voltage.
• Connect the test leads parallel to the source being measured.
• Read the voltage value on the LCD display [9] along with the polarity of the red lead
connection.
• For AC measurement, press the peak hold button [6] to hold either maximum or
minimum measured value (see Peak hold function).
AC (TRUE RMS)/DC CURRENT MEASUREMENT
• Make sure no test leads are connected to the V··CAP·TEMP·HZ jack [11] or COM jack
[10].
• Set the rotary switch [3] in the desired range (
, or ). If the
current to be measured is unknown beforehand, set the range switch in the highest range
position and then reduce gradually until the ideal resolution is obtained.
• Use the mode button [5] to choose between AC and DC current.
• For DC current measurements, press the DCA zero button [7] once to reset the display to
zero for relative measurements (indicated with
in the display).
• Press the trigger [2] to open the jaws [1] of the clamp. Enclose a single conductor within
the clamp and release the trigger [2]. Enclosing multiple conductors at the same time will
result in faulty measurements. For accurate measurements, always keep the jaws closed
during measuring.
• Read the current value on the LCD display.
• Note that when measuring large currents, a buzzing sound may be heard coming from the
jaws. This is normal behaviour which does not influence the measurement accuracy.
RESISTANCE, AUDIBLE CONTINUITY and DIODE TEST
• Connect the red test lead to the V··CAP·TEMP·HZ jack [11] and the black lead to the
COM jack [10].
• Set the rotary switch [3] in the
position.
• Make sure there is no voltage on the circuit/component under test.
• For resistance test press the mode button [5] until the symbol appears (default) in the
display. Connect the test leads to the resistor to be measured and read the value in the
LCD display. Disconnect one side of the device under test to avoid interference from the
rest of the circuit.
• For continuity test, press the mode button [5] until the
symbol appears in the
display. Connect the test leads to the circuit to be measured and read the value in the
LCD display. When the resistance is <35, a continuity buzzer will sound.
Note:
test current: <1mA
• For diode/transistors/ semiconductors/… measurements, press the mode button [5] until
the
symbol appears in the display. During measurement, a current is sent through
the semiconductor junction and the voltage drop is measured. When the junction passes
the test, indicated forward voltage will be 0.4~0.9V while reverse voltage will indicate
“OL”. When the diode is short circuited, both readings will be ±0mV; when open, both
measurements will show “OL”.
Note:
CAPACITY TEST
forward DC current: 0.3mA typical, open circuit voltage: 1.5VDC
• Connect the red test lead to the V··CAP·TEMP·HZ jack [11] and the black lead to the
COM jack [10].
• Set the rotary switch [3] in the
00 (28/11/2008) 5 Velleman
position.

DCM268N
• Make sure there is no voltage on the circuit under test by discharging capacitors prior to
measurement.
• Connect the test leads to the capacitor to be measured and read the value in the LCD
display.
FREQUENCY measurement
• Connect the red test lead to the V··CAP·TEMP·HZ jack [11] and the black lead to the
COM jack [10].
• Set the rotary function switch [3] in the
position.
• Press and hold the mode button [5] for ±3 seconds until the frequency range is indicated
in the display.
• Connect the test leads to the circuit under test and read the value in the LCD display.
TEMPERATURE
• Set the rotary switch [3] in the
position. Select °C or °F with the mode select
button [5], the selection is indicated in the display.
• Insert the side of the temperature probe adapter marked with “+” in the
V··CAP·TEMP·HZ jack [11] and the other side (“-”) in the COM jack [10].
• If not done already, insert the K-type probe into the probe adapter (only one way
possible).
• Hold the probe head to the device under test for ±30s and read the temperature in the
LCD display.
• Do not change the rotary function switch when the thermocouple is connected to the
meter.
7. Battery
• When the low battery indication ( ) appears, replace the internal battery.
• Always disconnect test leads and set the rotary switch [3] in the
position when
replacing the battery. Do not us the device without batteries installed.
• The battery cover is located on the back of the device and is closed with one screw. Remove
the screw and open the battery compartment.
• Remove the battery and insert a new 9V battery following the polarity as indicated in the
battery holder. Only use a new battery of the same type and specifications.
• Reinstall the cover and secure it with the screw.
• Remove the battery when the device will not be used for a long time to avoid leakage.
• Do not recharge non-rechargeable batteries and do not throw in fire as they may explode.
WARNING: handle batteries with care, observe warnings on battery
casing. Dispose of batteries in accordance with local regulations.
