Keep your fingers behind the probe barriers while using the device.
•
Never use the device to measure voltages that (may) exceed the max. input value for a
particular function.
•
Never touch wiring, connections or live circuits while the device is in use.
3. Maintenance
•
Disconnect all test leads from energised circuits prior to opening the housing.
•
Do not use the device unless the cover is in place and securely fastened.

qualified technician.
4. General Description
The DCM267 is a hand-held, battery-operated 3 ½ digital clamp meter for measuring DC and
AC voltages, AC current, resistance, frequency, temperature (°C & °F), diodes and continuity.
5. Description of the Front Panel
Jaws
They pick up the AC current flowing through the conductor.
Hold-button
Press this button to freeze the last reading and make the “H”-symbol appear on the display.
Press this button again to make the “H”-symbol disappear.
Function and Range Switch
Used to select functions and desired ranges as well as to (de)activate the meter.
Back light
Press the (
) “LIGHT”-button to activate the back light for
±
3 to 5 seconds.
Display
3 ½ digit LCD with 7 segments. Height : 18mm.
“VHz”-jack
This is the positive (+) input terminal for tension and frequency measurements. Connect the
red test lead to this input terminal.
“COM”-jack
This is the negative (-) input terminal for every type of measurement, with the exception of
current measurements. Connect the black test lead to this input terminal.
“
Ω
”-jack
This is the positive input terminal for resistance, diode and continuity measurements.
Connect the red test lead to this input terminal.
Temperature measuring socket
Connect a “K”-type thermocouple to this input terminal and contact the object to be measured
with the thermocouple.
Trigger
Press the lever to open the jaws. The jaws will close again when the lever is released.
