2.1 Function and range selector
A rotary switch is used to measurement Functions and Ranges. When the
switch is set to OFF position, the meter does not operate.
2.2 Transformer jaws
Pick up the AC current flowing through the conductor. Press the TRIGGER to
open the transformer jaws. When the finger press on the TRIGGER is
released, the jaws will close again.
2.3 Data hold
A push switch (Push ON, Push OFF. All ACA, ACV, DCV ranges with this
feature)
2.4 Input jacks
This meter has three input jacks that are protected against overload to the
limits.
During use connect the black test lead to COM jack and connect red test lead
to V Ωjack. The red test lead is depended on function selected.
The EXT jack is used for accept insulation tester unit EXT banana plugs, when
measurement insulation resistance.
3. Operating instruction
3.1 Measuring current
1. Set the rotary switch at desired AC range position. The transformer jaws pick
up the AC current flowing through the conductor.
2. When only the figure " 1" displayed, it indicates overrange situation and the
higher range has to be selected.
Wrong Correct

DCM266L VELLEMAN

3.2 Insulation test
(Option 500V insulation tester unit (not available in France and Benelux market))
1. Connect the insulation test unit V Ω, COM, EXT three bananaplugs to the
clamp meter V Ω, COM, EXT.
2. Set the rotary switch of the clamp meter at 2000MΩposition.
3. Set the insulation tester unit range switch to the 2000MΩposition.
4. Use the insulation tester unit of the test leads connect its L, E input connect to
being tested installation's. ( Test installation's must be power OFF.)
5. Set the insulation tester power switch to the ON position.
6. Depress the PUSH 500V push-push switch, the 500V on red LED lamp will
light. Clamp meter display reading is the insulation resistance value. If the
reading is below 19MΩ, change clamp meter and insulation tester unit to
20MΩrange, can be increase the accuracy.
7. If the insulation tester unit is not used, the power switch must shift to power
OFF position, and the test leads must leave the E, L input connect. That can
be increase battery life and prevent electrical shock hazard.
3.3 Measuring voltage
1. Connect the black test lead to the COM jack and the red test lead to the V Ω
jack.
2. Set the rotary switch at the desired DCV or ACV range position and connect
test leads across the source or load under measurement.
The polarity of the red lead connection will be indicated along with the voltage
value when making DC voltage measurement.
3. When only the figure " 1" is displayed, it indicates overrange situation and the
higher range has to be selected.
3.4 Measuring resistance
1. Connect the black test lead to the COM jack and the red test lead to the V Ω
jack.
2. Set the rotary switch at desired Ωposition and connect test leads across the
resistor under measurement.
NOTE :
1. If the resistance being measured exceeds the maximum value of the range
selected or the input is not connected, an overrange indication " 1" will be
displayed.
2. When checking in-circuit resistance, be sure the circuit under test has all
power removed and that all capacitors have been discharged fully.

DCM266L VELLEMAN
- 7 -
3.5 Continuity test
1. Connect the black test lead to the COM jack and the red test lead to the V Ω
jack. ( The polarity of the red lead is positive " +")
2. Set the rotary switch at position and connect test leads across two points of
the circuit under testing. If continuitiy exists ( i.e., resistance less than about
50Ω), built-in buzzer will sound.
4. Specifications
Accuracy is specified for a period of one year after calibration and at 18°C to
28°C (64°F to 82°F) with relative humidity to 80%.

6. Battery replacement
If the sign "BAT" appears on the LCD display, it indicates that battery should be
replaced. Remove the battery cover of case. Replace the exhausted battery with a
new one.
WARNING
Before attempting to open the battery cover, be sure that test leads have been
disconnected from measurement circuit to avoid electric shock hazard.
